Features of SC-40C 277-480 Volt 3-Phase Satellite Contactor

The ETI SC-40C 277-480 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.

Application Information

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.
