The patented SC-40C Satellite Contactor is a power control peripheral for a APS-4C Snow Switch and similar Environmental Technology, Inc. products. The APS-4C Snow Switch operates the SC-40Cs whenever its contactor operates. That is, during snow and for the hold-on time thereafter.

The integral ground fault circuit interrupter (GFCI) along with a test/reset facility ensure safety along with NEC and local code compliance. Partitioning heater loads for multiple SC-40Cs prevents the nuisance GFCI tripping that is often unavoidable when controlling a large system with a single contactor. The selftest facility operates heaters for one minute with a duty cycle limited to 33% for safer heater testing during the summer months.

An APS-4C operates up to ten SC-40Cs. The size and location of the heaters determines the number of SC-40Cs required. The APS-4C and its SC-40Cs can be separated by up to 1,000ft (305m).

Supply voltage options include 277 volt single-phase, 208-240 volts 3 phase, or 277/480 volt 3 phase, with a contactor rating of 50 amps per pole. For installation simplicity, SC–40C control wiring is NEC Class 2.

The SC-40C’s non-metallic enclosure is rated for protected NEMA 3R locations in the temperature range of -40˚ to 160˚F (-40˚ to 60˚C).
