ABB Tmax XT Circuit Breaker Accessory Under Voltage Release 48VAC/DC 1SDA069064R1 UVR XT1..XT4 48VAC/DC

ABB 1SDA069064R1 UVR XT1..XT4 48VAC/DC is a Circuit Breaker Accessory specifically engineered for Tmax XT series motor circuit breakers. This under voltage release (UVR) device allows the circuit breaker to automatically open in response to under voltage conditions including power failures or significant voltage drops.

The UVR ensures compliance with international standards by reliably triggering breaker opening when supply voltage falls between 70% and 35% of the nominal rated voltage (Un). Following a trip, the circuit breaker can only be reclosed once the voltage recovers above 85% of Un, providing enhanced protection and controlled operation. When the UVR unit is de-energized, neither the circuit breaker nor the main contacts can be closed, increasing operational safety in emergency or fault conditions.

Designed for seamless integration, the accessory operates at a rated voltage of 48 VAC/DC and is suitable for Tmax XT1, XT2, XT3, and XT4 series breakers. Installation is straightforward thanks to its compact dimensions: 60mm height, 110mm width, and 140mm depth. Its construction adheres to IEC 60947-2 standards and the environmental requirements of the RoHS directive, ensuring both performance and safety in electrical distribution systems.

Manufactured in Italy with premium quality assurance, this ABB accessory enhances the functionality and safety of electrical panels and industrial installations by providing reliable under voltage release capabilities.

The under voltage release triggers breaker opening between 70% to 35% of rated voltage. Allows breaker reclosing once voltage exceeds 85% of rated voltage. Ensures breaker and main contacts cannot close when UVR not energized.

Operates at rated AC/DC voltage of 48V. Compatible with Tmax XT1, XT2, XT3, and XT4 model breakers. Complies with IEC 60947-2 standards and RoHS directive. Compact design for easy fitting in electrical panels. Manufactured in Italy with strict quality controls.

Ideal for industrial, commercial, and electrical automation applications requiring enhanced circuit breaker protection and remote emergency opening features. Browse more ABB circuit breaker accessories at EnvMart for comprehensive electrical control solutions.
