ABB 1SDA066399R1 UVR-C wired undervoltage release for SACE Tmax XT1–XT4 fixed and plug-in circuit breakers. Rated for 220–240 V AC and 220–250 V DC, it provides undervoltage release functionality for compatible Tmax XT circuit breakers.
The ABB 1SDA066399R1 UVR-C is a wired undervoltage release designed as an electrical accessory for ABB SACE Tmax XT molded-case circuit breakers.
The unit is designed for XT1, XT2, XT3 and XT4 fixed and plug-in circuit breakers and operates at a rated voltage of 220–240 V AC or 220–250 V DC. ABB classifies the product as an Undervoltage Release (UVR) within its electrical and auxiliary-contact accessories.
An undervoltage release is used as part of a circuit breaker's control and protection arrangement, allowing the breaker mechanism to respond when the supply/control voltage falls below the required operating condition.
The wired configuration makes the 1SDA066399R1 suitable for integration with compatible Tmax XT circuit-breaker installations in industrial electrical distribution, control panels, commercial facilities and infrastructure applications.
