TERASAKI TemPower - Model 2 ACB -Advanced Air Circuit Breakers for Critical Installations

Air circuit breakers are critical components in ensuring the safety and protection of electrical installations. These devices are designed with a short-time withstand rating that matches their service breaking capacity, which guarantees optimal discrimination and selectivity. This feature allows for time-delayed short-circuit protection even at maximum prospective short-circuit currents. Key features include adjustable time-delayed overcurrent protection, short-circuit protection, and instantaneous protection, as well as adjustable time-delayed ground fault protection. These breakers are essential for increasing the reliability and lifespan of mission-critical installations by offering practical methods for safeguarding against faults. The advanced protection relay, AGR-31BR-PG, provides an LCD energy monitor with various adjustable curves such as standard inverse, very inverse, and extreme inverse, along with ground fault and fault indication contacts. These features make air circuit breakers indispensable for enhancing the endurance and protection of complex and vital electrical systems.
