Crystal Electric Co. Private Limited

We supply Off Load Side Handle Change over Switches, which are ideal for off load applications. Developed in conformation with international quality standard, our range prevents the accidental opening of the changeover switch in "on" position. We also offer customization on our range as per the specification detained by clients.
   
Features:

• High endurance
• Heat resistance
• Compact design
• High mechanical and dielectric strength

We provide On Load Changeover Switches (Compact Version), which are basically a 4 pole switch and are manually operated.  Developed in compliance with IEC-947-3IS: 13947 Part (I&III) – 1993 and IEC: 664 quality standards, these switches saves the space in panel boards resulting in low costing of panel boards. Our range includes two On Load Switch Disconnectors that are joined together and are mechanically interlocked with common outgoing. These compact designed On Load Changeover Switches are mainly used in low voltage distribution circuits and motor circuits and at places where continuity of supply is required for switching from main supply to an alternate source of supply and vice versa.

Moreover, our range is capable of making, carrying & breaking currents under normal circuit conditions, which may include operating under overload conditions and also carrying currents under specified abnormal circuit conditions.

Features:

• Compact & Standardised sizes for range 63 A - 3150 A as compared to leading indigenous makes, thus saves panel space & cost.
• While breaking the circuit, guaranteed sufficient air sectioning clearance.
• Protection against over currents & short circuit fault of high rupturing capacity upto 80 KA.
• Strong endurance & resistance to heat (Tropicalised).
• Phase barriers between each phase terminal.
• Flag indicator for three stable positions i.e. (I-O-II) & possible switching from one source to the other, on load, thereby fulfilling the role of switching device with interlocking protection for two modes of supply, one from electricity board & other from standby source i.e. generator and providing back up.
• The shorting link can be connected on either side to facilitate interchangeability of line and load.
• Auxiliary contacts up to 2 NO & 2 NC for signalisation & interlocking.
• The moulded body's raw material is glass fiber reinforced polyester (SMC), having high mechanical & dielectric strength.
• Strong & ergonomic operating handle with door interlock & padlock facility.
• Utilization category -AC 23 A.

Our range of On Load Switch Fuse Changeover (Open Execution) are used at places where continuity of supply is essential that is maintained by switching to an alternate source of supply from main supply and vice versa. Fitted with HRC fuses in load circuit, our range of fuse changeover meets the requirement of IEC: 947-3, IEC: 664 and IS: 13947 Part (I&III) – 1993 quality standards. These are manually operated and are capable of making, carrying & breaking currents under normal circuit conditions, which may include operating under over load conditions and also carrying currents under specified abnormal circuit conditions, such as short circuit for a specified time. Our compact designed 4 pole switch fuse finds application in low voltage distribution circuits and motor circuits. Features: Unique modular construction comprising On Load Changeover Switch with HRC fuses in load circuit Four breaks per pole resulting in faster quenching of arc. While breaking the circuit, guaranteed sufficient air sectioning clearance. Protection against over currents & short circuit fault of high rupturing capacity upto 80 KA. Compact & Standardized sizes for range 63A-800 A ideal for switch board manufacturers. Strong endurance & resistance to heat (Tropicalised) Flag indicator for three stable positions (I-0-II) & possible switching from one source to the other, on load, thereby fulfilling the role of switching device with interlocking protection for two modes of supply, one from electricity board & other from standby source i.e. generator and providing back up. Phase barriers provided between each phase terminal and HRC fuses. Large terminal area suitable for aluminum/copper busbar and cables.
