Mars 16025 220V Potential Relay

Description

Mars 16025 220V Potential Relay Overview

The Mars 16025 is a 220V potential relay engineered for reliable single-phase compressor motor starting in HVAC and refrigeration systems. Potential relays play a critical role in compressor protection by dropping the start capacitor out of the circuit once the motor reaches its designed operating speed — reducing electrical stress, extending capacitor life, and improving overall system efficiency.

How a Potential Relay Works

During motor startup, the start capacitor provides the extra torque needed to bring the compressor up to speed. As back-EMF (electromotive force) rises across the start winding, the potential relay coil energizes and opens its normally closed contacts, removing the start capacitor from the circuit. This seamless transition protects both the capacitor and the compressor motor from sustained high-current draw.
