Siemens SJD69200G Molded Case Circuit Breaker

Siemens SJD69200G is a 200 A, three‑pole, 600 V AC molded‑case circuit breaker from the Sentron JD frame family, designed for main feeder protection in industrial and commercial electrical distributions. This bolt‑on device uses an electronic trip unit (ETU) with Sensitrip technology, delivering Long‑Time, Instantaneous, and Ground‑Fault (LIG) protection for reliable short‑circuit interruption. It offers an interrupting capacity of 25 kAIC at 600 V and 35 kAIC at 480 V, depending on the system voltage, and complies with UL 489 / IEC 60947‑2 standards. Line and load side lugs are TA2J6500, with a wire range of 3/0 AWG to 500 kcmil copper or 4/0 AWG to 500 kcmil aluminum. The breaker is JD frame, 40°C rated, and configured for bolt‑on mounting. Its compact footprint is about 7.5 in wide by 11 in high by 4 in deep and it weighs roughly 20 lb, making it suitable for use in distribution panels, motor control centers, and service entrances where robust protection for 3‑phase circuits is required.
