Сетевой ETI Snow Switch SC-40C

The SC–40C Satellite Contactor answers the need for cost-effective modular snow melting heater control. One or more SC–40Cs, when used with an APS–4C Control Panel acting as the master control, allow for modular snow melting system design. There is no limit to the number of SC–40Cs that can be interfaced in a single system. This approach reduces front end design, hardware, and installation costs while providing a number of useful features that would be otherwise too expensive and complex to implement. The SC–40C provides the same advanced patented and patent pending Ground Fault Equipment Protection (GFEP) as required by the USA and Canadian National Electric codes that are found on the APS–4C. Upon sensing a ground fault condition, an SC–40C inhibits operation of its contractor until manually reset. Circuits without a ground fault continue to operate normally thus partitioning defective heaters.
