The TERASAKI 93.0.926, also known as the ATR-20A, is an electronic trip relay specifically engineered for use with Terasaki’s TemPower 2 series of Air Circuit Breakers (ACBs). This crucial component serves as the brain of the circuit breaker, providing reliable and precise overcurrent protection. It offers adjustable settings for Long-time (overload), Short-time, and Instantaneous protection functions, allowing users to fine-tune the breaker’s response to electrical faults. The ATR-20A ensures the safety and integrity of electrical systems by accurately detecting and tripping the breaker during overcurrent conditions, thereby preventing damage to valuable equipment and minimizing downtime in industrial and commercial applications.
