1SDA066408R1 ABB - UVR-C XT2-XT4 W 480-525 VAC

The 1SDA066408R1 is an undervoltage release (UVR) designed for ABB Tmax XT series circuit breakers, specifically the XT2 and XT4 models. This UVR is wired for withdrawable (W) type circuit breakers, ensuring compatibility with systems where the breaker needs to be easily removed for maintenance or replacement. It provides protection against voltage drops, automatically tripping the circuit breaker when the voltage falls below a certain threshold. This prevents damage to connected equipment and ensures safety in electrical systems. The UVR-C XT2-XT4 W 480-525 Vac is designed to operate within a voltage range of 480 to 525 Vac. It enhances the reliability and safety of electrical installations by providing an automatic disconnection mechanism in case of undervoltage conditions. This device is crucial for maintaining stable power supply and protecting sensitive equipment from voltage fluctuations. Its withdrawable design simplifies maintenance and reduces downtime. The undervoltage release mechanism ensures that the circuit breaker trips when the voltage drops below the set threshold, preventing potential damage to connected equipment. This feature is essential for maintaining the integrity and safety of electrical systems.
