Siemens SHJD69200 Electronic LI Circuit Breaker

Siemens SHJD69200 is a 3‑pole Sentron Molded Case Circuit Breaker from the SHJD6‑A family, equipped with a Sensitrip III electronic trip unit (LI: Long‑Time and Instantaneous) that uses true RMS current sensing to deliver precise protection for 3‑phase, 3‑wire systems up to 600 V. Rated for 200 A, this bolt‑on device supports short‑circuit interruption of up to 35 kAIC at 600 V and 65 kAIC at 480 V, with lugs not included to allow flexible mounting in switchboards or panel assemblies. The digital trip unit continuously monitors load current and fault conditions, enabling predictable, fast tripping decisions and reducing nuisance trips compared with purely mechanical breakers, a characteristic benefit of the Sensitrip III platform. Intended for industrial applications, SHJD69200 is well suited to protect feeders, motors, and distribution circuits in power panels, motor control centers, and automation cabinets; it is UL 489 listed and designed for robust operation in demanding environments. Being part of the Sentron line, SHJD69200 integrates with other Siemens protection devices to support coordinated protection across panels and equipment.
