Product ID:2CDE160000R0901

Catalog Description:Priority Switch

Long Description:

Priority switches are used in installations where existing conductor cross-sections or the size of the power supply connection do not permit simultaneous operation of two powerful consumers (e.g. storage heater ａnd heat exchanger). Priority switches disconnect the long-term consumer (storage heater) as long as the short-term consumer (heat exchanger) is switched on. The current coil of the priority switch is connected in series with the short-term consumer. When the consumer is switched on, the contact of the priority switch disconnects e.g. the contactor of the heating system.
