      DC Switches

      HOMA manufactures DC switches for a variety of DC applications. These can operate under voltages of up to 3.000V DC. The HOMA product range includes switches and switching combinations with positive and negative contacts. HOMA switches are being used for many years in applications that have to operate under high temperatures and continue to conduct and switch high voltages. By using silver contacts and therefore having low ohmic losses, HOMA switches improve the energy balance and reduce energy losses. DC switches can reach switching periods of under 16 milliseconds.

      Medium-frequency contactors up to a maximum of 24000A / 3.000V

      Capacitor contactors up to a maximum of 1.000A / 3.000V < 10kHz

      High current switches (off Load)

      Cut-off and changeover switches up to a maximum of 50.000A / 3.000V / 0-150kHz

      Air- and water-cooled commutators and pole-reversal contactor up to a maximum of 25.000A

      Command units to control recurring switching operations

      Contact installations for galvanic-technology in the form of air- and water-cooled prism or sliding contacts up to a maximum of 20.000A




      HOMA High Current Technology develops and manufactures AC and DC bar mounted contactors for motor starter applications, foundries and steel furnaces, solar and wind turbines, railway, battery test devices, ripple control systems, rolling mills and cranes since more than 60 years.


      HOMA is a system supplier for renowned manufacturers. Beside manufacturing contactors as a component, HOMA is capable to develop, manufacture and install turnkey solutions for complex requirements including supply of control cabinets and power electronics. HOMA DC Switches are used in the starter industry as Shorting Switches, Disconnectors.
