MARS 19007 Relay

The MARS 19007 is a trade-standard 68 potential relay designed for high-reliability motor starting in refrigeration and HVAC applications. Engineered for direct service substitution, the MARS 19007 is technically identical to the 90-68 potential relay, offering a 502V continuous coil voltage rating that handles demanding electrical environments. As a non-positional relay, it provides maximum mounting flexibility, which is critical when working in tight compressor compartments where vertical orientation isn't always feasible.

This universal replacement potential relay features a wide calibration range with a pick-up voltage of 325-345V and a drop-out voltage of 135V, ensuring precise control of the start capacitor circuit. Each unit includes a universal break-off bracket to match existing mounting footprints and a QC-6 kit to convert screw-type terminals to push-on connections in the field. For technicians performing compressor troubleshooting, this cULus listed component is a necessary HVAC service part for restoring capacitor start induction run (CSIR) and capacitor start capacitor run (CSCR) motor functionality across thousands of OEM models.

• Universal Compatibility: Interchanges with MARS 68, 90-68, and several GE 3ARR3 series relays to reduce truck stock.
• Installation Versatility: The non-positional design and snap-off bracket allow for seamless integration in any orientation.
• Field Conversion: Includes a QC-6 kit allowing you to switch between screw-on and push-on terminal styles on-site.
• High Voltage Threshold: Rated for a 502V hold voltage, providing a robust buffer for transient voltage spikes in commercial systems.

Is the 19007 a direct replacement for the RBM 90-68?
Yes, the MARS 19007 is the technical equivalent and direct replacement for the 90-68 and Packard PR9068 models.

Can this relay be mounted horizontally?
Yes, this is a non-positional potential relay, meaning it will operate accurately regardless of its mounting angle.

What is the maximum contact rating?
The contacts are rated for 35 amps at 277 VAC, making it suitable for a wide range of fractional and integral horsepower compressors.
