MARS 19167 Potential Relay

The MARS 19167 Potential Relay (Model 167) is a precision-engineered motor starting component designed for heavy-duty HVACR applications. This 420V potential relay features a specific pickup voltage range of 300V to 328V and a dropout voltage of 60V to 121V, ensuring accurate capacitor cutout once the motor reaches sufficient speed. Built with a 35 Amp contact rating and a 50/60 Hz universal frequency range, it provides reliable switching for high-torque compressors and motors.

Designed as a universal potential relay replacement, the 19167 incorporates a universal break-off bracket and 1/4 inch quick-connect terminals for seamless integration into existing control panels. Its Class B insulation and non-positional capability allow for flexible mounting configurations without compromising the electromagnetic integrity of the coil. This relay is a direct professional-grade solution for technicians requiring high-voltage coil performance and consistent motor start assist functionality in demanding environments.

• Precise Voltage Calibration: Ensures accurate 300-328V pickup to prevent premature capacitor engagement or excessive motor winding heat.
• Universal Compatibility: Replaces thousands of OEM models, reducing inventory needs for common service calls.
• High Amperage Capacity: The 35A contact rating accommodates 1/3 HP motors and standard refrigeration compressors.
• Durable Construction: Rated for 420 VAC continuous coil operation with enhanced Class B insulation for long-term cycle reliability.
