1SDA054880R1 ABB - UVR T4-T5-T6 24...30 VAC/DC

The 1SDA054880R1 is an undervoltage release (UVR) designed for use with ABB T4, T5, and T6 series circuit breakers. This device provides protection against undervoltage conditions, ensuring that the circuit breaker trips when the voltage drops below a specified threshold. The UVR operates within a voltage range of 24 to 30 Vac/dc, making it suitable for various power systems. It is an essential component for maintaining the safety and reliability of electrical installations. When an undervoltage event occurs, the UVR triggers the circuit breaker to open, preventing damage to connected equipment. This helps to avoid potential hazards and ensures the continued operation of critical systems. The 1SDA054880R1 UVR is easy to install and integrate with compatible ABB circuit breakers. It offers a compact design and reliable performance, making it a valuable addition to any electrical protection system. Its robust construction ensures durability and long-term operation in demanding environments. This UVR enhances the overall safety and efficiency of electrical distribution networks.
