1SDA066406R1 ABB - UVR-C XT2-XT4 W 220-240VAC-220-250VDC

The 1SDA066406R1 ABB - UVR-C XT2-XT4 W 220-240Vac-220-250Vdc is an undervoltage release (UVR) designed for use with ABB's XT2 and XT4 series withdrawable circuit breakers. This device provides protection against voltage drops, ensuring that the circuit breaker trips when the voltage falls below a predetermined level. The UVR-C is wired for operation within a voltage range of 220 to 240V AC and 220 to 250V DC, offering flexibility in various power systems. It is crucial for maintaining the safety and integrity of electrical systems by preventing equipment from operating under insufficient voltage conditions. This undervoltage release mechanism enhances the reliability of the circuit breaker by automatically disconnecting the circuit during voltage sags or failures. Its compatibility with withdrawable circuit breakers simplifies installation and maintenance procedures. The UVR-C unit promptly responds to voltage fluctuations, minimizing potential damage to connected loads. By integrating this UVR, electrical systems gain an additional layer of protection against voltage-related issues. This device is essential for applications where maintaining a stable voltage supply is critical for operational safety and efficiency. The ABB UVR-C ensures that the circuit breaker operates reliably under a wide range of voltage conditions, preventing unexpected equipment failures.
