ABB S2C-A1U Safety Relay

ABB S2C-A1U is a UL489‑certified shunt‑trip safety relay that remotely trips ABB S200 U circuit breakers (and S200 UP) when its coil is energized. The single 12–60 V AC/DC coil accepts a voltage signal to latch and release, and the unit is designed for right‑side field mounting in control panels with the coil wired to the 12–60 V range; the 2CDS200908R0001 designation identifies the specific coil assembly. This device, part of ABB’s S2C family, provides a dedicated safety interlock function by energizing the coil to open the breaker contacts, enabling immediate isolation in safety circuits that require UL489 compliance. Intended for protection schemes in industrial controls, it is commonly used where remote tripping of S200 U/S200 UP breakers is required for safe machine shutdown.
