Product Profile of On Load Switch Fuse Changeover [open Execution]

Crystal electric co. Pvt. Ltd. Is an iso 9001: 2000 certified company is the manufacturer and exporter of switch gears. Crystal electric co. Pvt. Ltd. Manufactures and exports on load switch fuse changeover. Switch fuse changeovers are manually operated 4 pole switch fuse with compact design for application in low voltage distribution circuits and motor circuits. These are used at places where continuity of supply is necessary which is maintained by switching to an alternate source of supply from main supply and vice versa. Switch fuse changeovers are fitted with hrc fuses in load circuit.

Salient features
1. unique modular construction comprising on load changeover switch with hrc fuses in load circuit.
2. four breaks per pole resulting in faster quenching of arc.
3. while breaking the circuit, guaranteed sufficient air sectioning clearance.
4. protection against over currents & short circuit fault of high rupturing capacity up to 80 ka.
5. compact & standardized sizes for range 63a-800 - an ideal for switch board manufacturers.
6. strong endurance & resistance to heat [trivialized].
7. 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.
8. phase barriers provided between each phase terminal and hrc fuses. 9. auxiliary contacts up to 2 no & 2 nc for signalization & interlocking. 10. the molded body`s raw material is glass fiber reinforced polyester smc which has high mechanical & dielectric strength. 11. strong & ergonomic operating handle with door interlock & padlock facility. 12. utilization category - ac 23 a.
