Product Profile of On Load Changeover Switches [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 changeover switches. On load changeover switches are manually operated 4 pole switches with compact designed for application in low voltage distribution circuits and motor circuits. These are used at places where continuity of supply is necessary which maintained by switching to an alternate source of supply from main supply & vice versa. Salient features 1. all current carrying parts are of special grade e.T.P copper and with silver electroplated. 2. no load / line restriction-the shorting link can be connected on either side to facilitate interchangeability of line and load. 3. while breaking the circuit, guaranteed sufficient air sectioning clearance. 4. protection against over currents & short circuit fault of high rupturing capacity 80 ka. 5. compact & standardized sizes for range 63a-800a - ideal for switch board manufacturers. 6. strong endurance & resistance to heat [trivialized]. 7. flag indicator for three stable positions [ i - o - ll ] & possible switching from one to the other on load, there by fulfilling the role of switching device with protection from two modes of supply, one from electricity board and other by stand by source i.E. Generator and providing backup protection.

8. the switches are available in open execution as well as in fabricated enclosure with thick steel sheet duly phosphating with seven tank processes and finished with powder coating.
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. phase barriers between each phase terminal.
12. mounting is possible in horizontal and vertical position.
13. strong & ergonomic operating handle with door interlock & padlock facility.
14. utilization category - ac 23 a
