Air-break contactors and combinations of switches to deal with normal to complicated switching activities for all types of electrical loads.

HOMA Contactors and Switches - Switching


Sliding contacts, air-break contactors and air- or water-cooled high current switches for galvanic interruption of circuits without a control current for technical or safety reasons.

HOMA Contactors and Switches - Isolating


Different types of commutators to select different sources or for an alternative supply of the electrical load circuit.

HOMA Contactors and Switches - Distributing


Commutators and pole-reversal contactor including associated control systems, reversing contactors etc. for process-related reversion of the electrical current or rotational direction; braking contactors for switch-off for drives that simultaneously trigger dynamic braking systems.

HOMA Contactors and Switches - Controlling


Starting contactor / rotor-short circuit contactor, as well as starting coupling contactor / cascade coupling contactor for large machinery in association with subsynchronous static Kramer systems; capacitor contactors for balancing or compensating inductive electrical loads. Starting, damping and discharge resistors.
