C137, C163 and C164 Single Pole DC Contactors

The C137, C163 and C164 are single pole DC contactors suitable for carrying direct currents in the range of 40 amps to 140 amps for all common battery voltages of up to 110 volts.

The battery contactors are available as single pole make contacts with magnetic blowout or as single pole changeover contacts with an additional galvanically isolated break contact.

The contactors are suitable for switching small or medium loads and for use with all kinds of electric vehicles in material handling. Coming with double-break contacts, the DC changeover and reversing contactors are designed for switching resistive, capacitive and inductive loads.
