CU Series Double Pole DC Contactors

The CU1215/06 is a double-pole NO contactor for DC (unidirectional). It has a rated insulation voltage of 3,000 V and conventional thermal current of 1000 A.

The CU range expands Schaltbau’s array of new and innovative switchgear in the power category up to 1000 A. The switchgear ensures low-wear and reliable switching of high loads, while the double coil drive reduces the power consumption in holding operation.

Power contactors of the CU range are suitable for use in photovoltaic systems (in the DC circuit of central inverters) as well as in power supply and battery systems, such as for UPS systems.
