Siemens SO1ED60 U Circuit Breaker 3-Phase Panel Mount

Siemens Sentron S01ED60 U shunt-trip accessory for ED-frame molded‑case circuit breakers provides a 120 VAC actuation coil that enables remote tripping for emergency shutdown, interlock, or automation fault‑response scenarios. Designed for left‑pole mounting on 125 A ED‑frame devices, it attaches to the associated breaker to add a dedicated trip actuator without replacing the main unit. The unit measures approximately 3 in. long by 6 in. wide by 7 in. high, suitable for panel installations where remote activation of protection is required. As part of the ED‑Frame family, the S01ED60 U complements standard protection by providing an independent trip path that can be integrated with control systems, PLCs, or safety interlocks in commercial and industrial electrical installations.
