The TERASAKI 986034702 is an Under Voltage Trip (UVT) coil, also known as an Undervoltage Release (UVR), engineered as a critical accessory for the Terasaki TemPower 2 series of Air Circuit Breakers (ACBs). This component provides essential protection by continuously monitoring the control circuit voltage. If the voltage drops below a specified threshold (typically 35-70% of the rated voltage), the UVT coil automatically trips the circuit breaker, safeguarding connected equipment from potential damage caused by undervoltage conditions. It also prevents the breaker from being closed until the voltage returns to a safe and stable level (typically above 85% of the rated voltage). This genuine Terasaki part ensures reliable performance and enhances the safety and operational integrity of your electrical distribution system.
