ABB 1SDA066406R1 UVR-C XT2-XT4 W 220-240Vac-220-250Vdc Undervoltage Release Withdrawable Tmax XT

The ABB UVR-C XT2-XT4 W 220-240Vac-220-250Vdc (SKU: 1SDA066406R1) is a withdrawable undervoltage release accessory designed for use with ABB Tmax XT2 and XT4 series moulded case circuit breakers. Rated for 220–240 V AC and 220–250 V DC control supply, this compact 0.12 kg release trips the breaker automatically when the supply voltage drops below the set threshold, safeguarding motors, control panels, and critical industrial loads against the damaging effects of undervoltage conditions.
