Crane Rail Heating Control Panels

Thermal-Flex crane rail heating 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 control functions for crane rail heaters.

The two essential control functions are turning on and off the heating cable, 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 a control point.  Other functions are offered for specific applications.

Thermal-Flex crane rail heating control panels are available from single circuit to multiple circuit configurations.  Optional control panel accessories include a variety of sensing devices permitting the heating elements to be remotely activated.
