It trips on 110...127 V AC or 110...125 V DC. Active lifecycle status, no last-time-buy notice. On the AC side, the lower bound of 110 V accommodates a sagging 120 V control bus under load; the 127 V ceiling covers a nominal 120 V +10 % tolerance. On the DC side, 110-125 V covers standard station battery ranges. The release is IEC-listed, which means it meets the performance and safety requirements of the International Electrotechnical Commission — the default standard for global panel builds outside North America (where UL 489 also applies, and the order code KT3S4 covers the UL/CSA variant). This release mounts into the breaker's accessory slot on the Tmax T1, T2, or T3 frame — no additional DIN-rail space needed. The coil draws from the control circuit, not the main power path, so it's wired separately through the breaker's auxiliary terminal block. Verify the free-wheel diode polarity on the DC side before energizing; reversed polarity on a DC shunt release can weld the plunger.","metaTitle":"ABB 1SDA053681R1 SOR-C Shunt Release, 110-127V AC/DC, for Tm","metaDescription":"ABB 1SDA053681R1 SOR-C shunt release for Tmax T1-T3.
