High Voltage Contactors
RXC61 Series
The RXC61 Series are hermetically sealed high voltage DC contactors designed for high-current power switching in demanding applications. Rated for continuous currents up to 600 A and system voltages up to 1,500 VDC, the RXC61 Series features bi-directional switching, integrated coil economization, and mechanically linked auxiliary contacts for reliable position feedback. Designed and assembled in the USA, these contactors are ideal for energy storage systems, electric vehicle battery systems, charging infrastructure, AI data center backup power systems, humanoid robotics, AGV’s, and industrial DC power control.

Datasheet notes
- Integrated coil suppression limits back-EMF to 0 V. External diodes or suppressors do not affect operation.
- Contactor may be used above Max Switching Voltage if the application does not require significant load breaking. Please contact Rincon Power for more details.
- Attach cables and busbars directly to the main terminal pad using the recommended install torque. Do not use washers or other materials between the contactor power terminals and the conductor.
- Dual coil economizer design: Pickup Voltage must be applied as a pulse. Do not ramp voltage.
- Rigid busbar structures have the potential to induce stress into the device and can damage the hermetic seal. When using busbars, it is important to design compliance into the bus bar structure via the use of flexible laminated busbars and or by means of incorporating adjustability in adjacent bolted interfaces.
