KC6-31Z 220-240VDC

The ABB KC6-31Z-05 Mini Contact Relay is a compact, 4-pole contactor relay designed for control and switching applications in residential, commercial, and light industrial environments. It is intended for switching control signals and small loads and is especially suited where space is limited and reliable operation is required. The device features a DC-operated coil with low power consumption, screw-type terminals for easy wiring, and robust construction for long operational life. Its noiseless, hum-free coil design and clear switching indication make it ideal for automation panels and control circuits with DC control voltages of 220-240 V.
