The ETI SC-40C 600 Volt 3-Phase Satellite Contactors are designed to be used along with the ETI APS-4C snow and ice melting control to allow for a modular snow melting system design. There is no limit to the number of SC-40 contactors that can be interfaced into a single snow and ice melting system. Modular power control of automatic snow melting systems No limit to the number of SC-40 contactors that can be interfaced into a single system Staged heater operation for high power quality Energy management computer (EMC) interface Accommodates MI, constant wattage and self limiting heaters Advanced patented and patent pending Ground Fault Equipment Protection (GFEP) as required by the USA and Canadian National Electric codes 10 hour adjustable heater hold-on timer to ensure complete melting C-UL-US
The SC-40C satellite contactors do not directly use snow and ice sensors but rather the contactors are notified of snow conditions by the master ETI APS snow and ice melting controller.
