UVR T1-T2-T3 110...127VAC-110...125VDC ABB - 1SDA051347R1

The ABB 1SDA051347R1 is an undervoltage release (UVR) designed for Tmax T series circuit breakers, specifically T1, T2, and T3 models. This device provides protection against voltage drops, ensuring that the circuit breaker trips when the voltage falls below a certain threshold. It is compatible with both AC and DC power sources, operating within a voltage range of 110 to 127Vac and 110 to 125Vdc. The UVR unit is wired for easy integration into existing systems. By monitoring the voltage level, the UVR prevents equipment damage and ensures safe operation. When an undervoltage condition is detected, the UVR automatically trips the circuit breaker, disconnecting the power supply. This helps to avoid potential hazards and maintain the integrity of the electrical system. The ABB 1SDA051347R1 undervoltage release is a reliable and essential component for safeguarding electrical circuits and equipment. Its dual compatibility with AC and DC voltages makes it versatile for various applications. This device enhances the safety and reliability of electrical installations by providing crucial undervoltage protection.
