Siemens S01JLD6 U 120 Relay

Siemens S01JLD6 is a Sentron shunt-trip accessory for molded‑case circuit breakers in the JD/LD/LMD family, providing remote-trip capability via a 120 V AC control circuit. It is designed for right-pole mounting on JD/LD/LMD frames, with connection options including pigtail leads (as listed by major distributors) and alternate wire-lead configurations, to simplify integration with existing control wiring. This 120 VAC shunt-trip accessory is intended to be used with Siemens Sentron molded‑case breakers to enable remote shutdown in safety-critical applications such as industrial control panels, motor control centers, and distribution boards. When the control voltage is applied, the shunt-trip mechanism energizes to trip the breaker, isolating power quickly without requiring manual operation and allowing protective interlock schemes to respond to external signals, alarms, or logic. The S01JLD6 designation distinguishes this model from variants that pair a shunt trip with an auxiliary contact or other options within the same JD/LD/LMD family.
