High Voltage Contactors

RXC15 Series

Name: RXC15 Series high voltage DC contactor
Brand: Rincon Power
SKU: RXC15

The RXC15 Series are hermetically sealed high voltage DC contactors designed for medium-current power switching in harsh and demanding environments. Rated for continuous currents up to 225 A and system voltages up to 1,000 VDC, the RXC15 Series features integrated coil economization and auxiliary contact options for efficient operation and reliable position feedback. The hermetic seal provides protection against moisture, dust, and contaminants, making these contactors well suited for mobile, industrial, and off-road applications including heavy trucks, buses, marine equipment, and industrial machinery.

Datasheet notes

Dual coil economizer design: Pickup Voltage must be applied as a pulse. Do not ramp voltage.
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.
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.
Avoid excessive coil voltages. Exceeding the ratings on the datasheet may result in high coil temperature and coil failure.
Integrated coil suppression limits back EMF to 150 V.
Polarity Sensitive versions are marked + and - for the power terminals. For applications that require the contactor to switch under load, please ensure current is flowing from the + to the - terminal when breaking/opening under load For Bi-Directional versions the direction of current does not matter when breaking under load.
M5 mounting fasteners are compatible with thru-hole mounting applications. Ensure that the fastener shoulders overlap the compression inserts extending to the plastic shoulders of housing. Use a flat washer if necessary. Recommended installation torque: [3.4 - 4.6 Nm] - Based on stainless fasteners.
M4 fasteners are recommended for applications requiring precise alignment with corresponding threaded mounting features. Ensure that the fastener shoulders overlap the compression inserts extending to the plastic shoulders of housing. Use a flat washer if necessary. Recommended installation torque: [1.8 - 2.5 Nm] - Based on stainless fasteners.
