High Voltage Contactors
RXC20 Series
The RXC20 Series are hermetically sealed high voltage DC contactors in a compact form factor designed for medium-current DC power switching in demanding environments. Rated for continuous currents up to 200 A and system voltages up to 1,000 VDC, the RXC20 Series features a robust SPST normally open contact arrangement with a hermetic ceramic gas-filled seal for long life and resistance to moisture, dust, and contaminants. With high temperature performance and an IP69 ingress rating, these contactors are well suited for rugged DC power control applications where space and reliability are critical.

Datasheet notes
- Contactor may be used above Max Switching Voltage if the application does not require significant load breaking. Please contact Rincon Power to discuss in more detail.
- Attached cables and busbars directly to the main terminal pad using the recommended install torque. Do not use washers or other materials between the contactor and the conductor. This will ensure the lowest possible contact resistance.
- Avoid excessive coil voltages. Exceeding the ratings on the datasheet may result in high coil temperature and coil failure.
- Polarity Sensitive versions are marked +A1 and -A2 for the power terminals. For applications that require the contactor under load, please ensure current is flowing from the +A1 to the -A2 terminal when breaking/opening under load For Bi-Directional versions the direction of current does not matter when breaking under load.
