Siemens SJD69300NGT is a 3‑pole molded‑case circuit breaker rated for 300 A at up to 600 V, suitable for protecting feeders and motor circuits in industrial power distribution. As part of the blue‑label SJD6 family, the NG T suffix indicates an LSIG trip profile—long‑time, short‑time/instantaneous, and ground‑fault protection. This compact MCCB is commonly installed in control panels and distribution boards where reliable overcurrent protection is required.
