Detailed Description

The YU E1.2..E6.2-XT7-XT7M accessory is an undervoltage release module designed for ABB SACE Emax 2 and Tmax XT circuit breakers, covering frame sizes E1.2 through E6.2.

It operates with a control voltage of 220 to 240 V, in both AC and DC systems, meaning it can trigger breaker opening when the auxiliary voltage drops below this level.

Identified by product code 1SDA073700R1, this module conforms to IEC standards and serves as a safety and protection accessory in low-voltage switchgear.

The module is compact and lightweight (approx. 0.15 kg) and is typically specified with details like packaging and certifications in manufacturer datasheets.
