Temperature-controlling-devices
Features
Temperature controlling devices feature magnetic contactors to handle loads which exceed power handling capabilities of line voltage thermostats. Heavy duty copper contacts carry heavy duty currents at line voltages. Holding coils are rated for line voltage but can be furnished for other voltages when specified.
