Capacitor discharge contactor 230V LC1DFKP7

Capacitor switching contactor LC1DFKP7 is designed for efficient switching of 3-phase capacitor banks with a power of up to 12.5kVAR at 400V and a frequency of 50Hz (or 21kVAR at 690V). The device operates at AC 230V, both at 50 and 60Hz. The contactor construction includes three normally closed main contacts and two normally open and one normally closed auxiliary contacts, providing flexibility in control circuit configuration.

The use of instantaneous auxiliary contacts (1NO + 2NC) in combination with early make poles and damping resistors mounted on the front limits inrush currents when switching capacitors on. This translates to increased durability and reliability of the entire system. The contactor is designed for frequent switching – up to 240 cycles per hour – while
