BCH 3 pole range of MCCB having ampere rating from 16 Amp to 630 Amp are available in three compact frame sizes – 100A, 250A & 630A.

BCH MCCB comes with high ultimate short circuit breaking capacity (Icu) & service short circuit breaking capacity (Ics) starting from 10 KA to 50 KA.

BCH MCCB offers protection flexibility with two type of trip units

• Thermal Magnetic Release
• Microprocessor Release ( LSIG)

Tested for 50°C Ambience

• We understand Indian conditions well, so the entire range of Resilient MCCB is tested for rated performance at 50°C.
• With every 5 Degree C dip in temperature, breaker can be uprated upto 4% depending on the rating.

Excellent Electrical / Mechanical Life

• Electrical life upto 10000 cycles and Mechanical life upto 25000 cycles, Resilient MCCBs are designed for longer life and reliability.

High Performance Compact Size

• Resilient MCCB offers 50 kA Short circuit breaking capacity in smallest frame size of 75 X 130 X 60 mm (WxHxD).

Outstanding Current Limiting Performance

• Owing to a salient U shaped terminal and fast acting mechanism, Resilient MCCB offers excellent current limiting performance
• Designed for a very low level of let through energy, Resilient MCCBs provides not only safety of installation but also reduces stress on downstream equipments

Flexibility of Installation

• Resilient MCCBs can be installed in any orientation i.e. vertical as well as horizontal orientation.

Line Load Interchangeability

• The entire range of Resilient MCCB is suitable for line load interchangeability, with unmarked terminals

Thermal Flexibility

• Adjustable overload protection : Upto 70 % to 100 % with Thermal Magnetic Release, 40% to 100% with Microprocessor Release (LSIG)

Unbeatable Flexibility of Accessory Mounting

• Resilient MCCB is one of its kind to have flexibility to install UV & Shunt Release together at a time for Frame 1 & Frame 2.
• Universal accessory mounting for UV Release, Shunt Release, Trip Alarm & Auxiliary switch for Frame 1 & Frame2.
• All accessories can be field fitted, with no need for dismounting breaker.

International Standards

• Entire range of Resilient MCCB is tested and certified as per IS / IEC 60947-2.
• Resilient MCCB also carries CE mark.

Suitability for Isolation

• Resilient Range of MCCB is suitable for positive isolation.
• Ensures complete safety of operator and installation.

Isolation of Accessories

• Internal accessory mounting chamber is isolated from main mechanism for safety of installation.
• Accessory must be mounted in TRIP condition.
• Rotary handle is lockable in OFF condition to prevent any unintended interventions to ensure operator safety.

Safety of Installation- Finger proof terminal.

Constructional features- The Resilient MCCB is meticulously designed to incorporate necessary design features for superlative performance

• Unique Design for Controlled exhaust of ARC to minimize safety perimeter & ground surface
• Inherent Contact System Design to provide wiping effect between Contacts for self-cleaning action
• Use of special ABLATIVE material generates gases to suppress ARC PLASMA & Quench ARC
• Maximized Contact Repulsion forces with U-Shape design for high ARC interruption capacity
• Bimetal senses Overload protection
• Electro Magnet senses Short Circuit Protection
