Additional information to the DC operation
EN 60947-4-1 specifies the utilization of contactors for switching DC currents. Contactors supplied by EPM can operate in categories DC-1, DC-3, or DC-5 with a max. voltage of 250 V, while the types VH250D0 and VH440 can even operate with a max. DC voltage of 440 V. Three main poles must be series connected (see the wiring diagram) for DC operating voltages above 48 V.
