With the new 3VT circuit breakers, Siemens offers an economic solution for the entire power range from 10 A to 1,600 A – the smart solution to protect plants, capacitors, transformers, generators and motors.Both for infrastructure applications as well as in the area of industrial switchgear technology, 3VT circuit breakers can be used as incoming and outgoing circuit breakers to distribute power in low-voltage switchgear. Available in several design variations, the modular circuit breakers are highly user-friendly, while also offering a high degree of safety and reliability.
The compact design of SENTRON VL family of Moulded Case Circuit Breakers (MCCB) coupled with their excellent features make things easier in the world of electrical distribution. Designed with minimum parts and maximum modularity, the new SENTRON VL range of Moulded Case Circuit Breaker (MCCB) offers two choices of trip units – “Thermo magnetic” trip unit and “Microprocessor” trip unit. The thermo magnetic (TM) range offers adjustable overload protection and is available from 20A to 630A.
The microprocessor (ETU) range in addition to wide band overload protection, offers the option of time selective short circuit protection and is available from 63A to 1600A. The incoming and outgoing side of the circuit breaker can be selected as desired. The SENTRON VL range of circuit breakers conform to the latest standards (IS 13 947 and IEC 60 947) and have been designed to protect cables, motors, transformers, wiring bus bars, as well as other plant equipment against thermal overload and short circuits.
Limit switches are used to determine the position of moving machine parts, doors or objects and to convert these positions into electrical signals forfurther processing in the control circuit. Special executions of SICONT 3SE3 limit switches are offered to suit various applications requiring ringcable lug termination. Construction:
Special 3SE3 limit switches are designed to enable easy termination of ring cable lugs
All contact blocks have a black moulded plastic housing, in which the fixed contacts areaccomodated
The moving contacts are located on the plastic slider (spring loaded) which performs double breakoperation
An extension plunger is also provided. These limit switches are available with 2 or 3 contacts.
Construction: The 3LAO switches are available in size 2 for 25 Amps. and size 6 for 63 Amps. They are made up of uniform switching packet assembly to form a stack. Each packet consists of 2 sets of contacts whose moving contacts are operated by moulded plastic cams when the operating shaft is turned.
The stacking of similar packets renders it possible to build switches for practically all types of small drives, offering at the same time a uniform appearance. This and their compactness make them ideal for installation on machine tools. The 3LAO switches are ordinarily supplied with either black moulded plastic ball handles or machine handles.
The 3LD2 main control and EMERGENCY-STOP switches represent safety-oriented switching devices which can be employed in multiple applications in accordance with the EN 60204 machine directive. They are suitable for switching main and auxiliary circuits as well as three-phase motors and other consumers in maintenance or repair cases. Highlights:
The bi metal overload relays type 3UA5/6 & 3UC5/6 relays are indigenously manufactured and bring to the users a whole range of benefits, which are a direct result of extensive R & D efforts in design, materials and manufacturing technology. They also incorporate additional features/benefits as a result of feedback from the users of our3UA19 relays. 3UA5 and 3UA5 are triple pole adjustable bi metal overload relays with built in single phasing protection. In conjunction with contactors and other motor control equipment, they provide accurate and reliable protection to motors against overload and single phasing as per 'Class 10A', in conformance to IEC 947-1-4 and IS 13947-4-1. They also offer protection against unbalanced voltages.

As a culture Siemens has always endeavoured to introduce innovative products worldwide. The Electrical Installation R&;D team has now raised the bar with the introduction of Betagard 5SL Miniature Circuit Breaker. Manufactured and designed at the Siemens Aurangabad facility, Betagard 5SL – Inspiring Safety, sets a new benchmark for protection.
Loaded with numerous features, Betagard 5SL is the only patented MCB with a unique SLR (Slide Latch-Release) feature for tool free removal of MCB from DIN rail. It also allows single MCB removal from a bus mounted assembly of MCBs. Betagard 5SL MCB is ergonomically designed and allows user-friendly switching. ON-OFF Status is easily recognizable thanks to the color coded switching position indicator on its attractive grey lever. With highly effective touch protection against accidental contact, Betagard 5SL range is available in current rating upto 63A in B and C characteristics.
Siemens introduces the new generation 3RP electronic timers to meet the various control timing requirements of industry. These timers comply withIEC 60 947-5-1IEC 61 000-6-2/EN 50 081-1 (EMC) Carry CE marking.
During installations, when the conventional HRC Fuses are mounted on the fuse bases or Switch Dis connector Fuse Units in panels as in Fuse Rails above certain height, it is very difficult to identify the status of the fuse link whether healthy or blown. This necessitates requirement of additional front indication.The combination indicator Fuse has two indicators as against one indicator in conventional fuses.One indicator is on top cover plate similar to conventional fuses and other indicator is at the centre of the ceramic body of the fuse link.This helps in clear identification of status of fuse even from front side.
Special attention has to be paid to the interaction between man and machine.Fault sources and system disturbances must be signaled reliably – and as early as possible and if things do get critical – the top priority is to safely and quickly stop machines and bring systems offline.
Our extensive range of 3SB5 commanding and Signaling devices is designed to meet the challenge. Push button actuators, selector actuators, key actuators, compact & modular indicators… our 3SB5 pilot devices let you handle every situation confidently. Application:
The 3SB5 range of pilot devices is eminently suitable for installation in any control and auxiliary circuit, AC or DC.Packed with user-oriented features, the 3BS5 push buttons and lamps are a practical state-of-the-art answer to the Indian customer‘s search for higher contact reliability, increased operator safety, reduced labour input (faster mounting and wiring), electronics compatibility and compactness plus IP65/67 degree of protection. The availability of 2 separate models – the rear wire connection type for panel mounting application and the ultra-compact front wire connection type for push button stations with removable covers render the 3SB5 devices ideal for panels, control desks, control stations, machine tools, etc.
Circuit Breakers today are no longer simple switching and protecting devices with ON/OFF and trip indications. Users today are looking at circuit breakers as a device, which integrates switching, protection, metering, and power management including quality of power from remote locations. Modern power systems are also characterized by the methods used to network circuit breakers - both with each other and with other components.
Siemens offers SENTRON WL family, which have a lot more to offer than even the so-called“the new circuit breaker” in the market. In future, it will not only be possible to carry out diagnosis and maintenance procedures remotely on the Internet, but real-time information about system mal-functions and alarm signals will be made available immediately to operating staff through SMS and mobile phones.
3TF power contactors are suitable for switching and controlling squirrel cage and slip-ring motors as well as other AC loads, such as solenoids, capacitors, lighting loads, heating loads and transformer loads.
SICOP contactors and bi-relays have been tested for type-2 coordination at IQ = 50kA, 415V, 50Hz as per IS:13947, for both fuse protected as well as fuseless motor feeders. We also offer special application specific contactor.
Siemens low voltage HRC fuses of BS type have been developed for industrial applications.
Due to the special design, they provide high rupturing capacity combined with low temperature rise under normal load conditions. The quick acting characteristics of the fuses ensure that under the worst fault conditions, cut off occurs before the peak value of fault current is reached. This ultimately reduces the electromagnetic stress and fire risk, thus avoiding premature failure of the downstream equipment.
