High Voltage Contactors
REC15 Series
The REC15 Series are epoxy-sealed high voltage DC contactors designed for compact, cost-effective DC power switching applications. Rated for continuous currents up to 150 A and system voltages up to 1,000 VDC, the REC15 Series delivers dependable DC switching performance in a widely adopted cylindrical form factor. Available with bi-directional main contacts and optional SPST-NO auxiliary contacts for position feedback, the REC15 Series contactors are suitable for production OEM applications where balanced performance and value are prioritized. The epoxy-sealed construction provides reliable protection for standard operating environments, making the REC15 Series an effective solution for battery power subsystems, industrial DC switching, and auxiliary power control.

Datasheet notes
- Bi-directional version is designed for maximum fault interrupt. As a result, no polarity sensitive version is required.
- For Bi-Directional versions the direction of current does not matter when breaking under load.
- The auxiliary contacts are connected internally via an armature on the main contact plunger. As the main contacts close, they automatically cause the auxiliary contacts to close.
- 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.
