MARS 16025 Relay

The MARS 16025 Potential Relay is a heavy-duty motor starting component engineered for high-demand HVACR applications. Specifically designed for 220V systems, this relay features a 35 Amp contact rating and is rated for motors up to 1/3 HP at 60 Hz. As a direct replacement potential relay for numerous OEM parts, the 16025 is built to handle the rigorous duty cycles of condenser fan motors and compressor start circuits. It operates with a precision-calibrated relay pick-up voltage range of 239 to 268 Volts and a drop-out voltage of 60 to 135 Volts, ensuring the start capacitor is reliably removed from the circuit once the motor reaches optimal operational speed. The unit facilitates an efficient HVAC motor start circuit integration with its integrated tab-type bracket and universal quick-connect terminals. This MARS 220V potential relay is a critical HVAC replacement part for technicians requiring a non-positional, UL-listed, and CSA-certified solution that interfaces seamlessly with existing wiring configurations and provides a maximum hold voltage of 500 Volts.

• Broad Compatibility: Serves as a 1:1 drop-in replacement for GE 3ARR3J4A4 and various Trane RLY series components.
• Heavy-Duty Construction: Features a high 35 Amp contact rating and 500V hold voltage for industrial-grade durability.
• Universal Mounting: Includes an integrated tab-style bracket on a plastic cover for flexible installation in tight control boxes.
• Technical Precision: Accurately manages start capacitor cutout based on back-EMF, protecting the motor from sustained high-torque starts.

What is the difference between pick-up and drop-out voltage on this relay?
Pick-up voltage (239-268V) is the threshold where the coil energizes to open the contacts and disconnect the start capacitor. Drop-out voltage (60-135V) is the level where the relay de-energizes to reset the circuit for the next start cycle.

Can I use the MARS 16025 to replace a GE 3ARR3J4A4?
Yes, the 16025 is specifically cross-referenced as a GE 3ARR3J4A4 replacement with identical mounting points and electrical specifications.

Does this relay require a specific mounting position?
This model is non-positional, meaning it can be mounted in any orientation without affecting the internal calibration of the potential-sensing coil.
