ABB 1SDA014138R1 Shunt Trip Opening Release BB3

The ABB 1SDA014138R1 is a 110 V shunt opening release designed to remotely trip ABB SACE Isomax breakers in the S6 and S7 families. As an auxiliary device, the release energizes to open the breaker, providing remote opening functionality for safety interlocks, control schemes, or emergency-disconnect scenarios in industrial power distribution and motor control centers. The part is explicitly identified as a Shunt Opening Release (SOR) for Isomax S6/S7, with a 110 V control voltage required to initiate the opening sequence. This accessory is intended to be mounted on compatible Isomax frames and works with the breaker’s trip mechanism to ensure a defined opening event upon energization. Typical applications include remote tripping from a central control system or protective-relay signals where rapid circuit isolation is necessary to protect equipment or personnel. Verify compatibility with the specific Isomax device and voltage configuration in your installation documentation before procurement and installation.
