Heater contactors manage the duty cycle of heaters, by switching them on and off according to a variable pattern related to the heat demand. Heating systems are supplied with high voltage, typically 3kV DC or 1kV AC (supplied by a secondary winding of the main transformer).
This application requires a challenging combination of high thermal current and electrical durability. We offer a wide variety of designs to fit most installation requirements.
- High making and breaking capability
- Suitable for heavy-duty electrical and mechanical operating conditions
