Switch Heater Control Panels
Thermal-Flex 200 and 400 Series Switch Heater Control Panels are a standardized component assembly of contactors, ground break equipment, circuit breakers, transformers, relays, fuses and other devices mounted on steel back panel-boards to provide specified control functions for 200 and 400 volt range A.C. switch heaters.
The two essential control functions are turning on and off the switch heater and ground fault protection. Other functions include local heater on, ground fault indication, circuit flow for remote control, and circuitry for indicating tripped ground fault at control point. Other functions are provided as required for specific applications.
