The SHP3B160G05 is a Siemens Sentron series molded case circuit breaker, rated for 1600 amps at 600 volts with 3 poles, designed for main and feeder protection in industrial plants, commercial buildings, and switchgear. With a high interrupting rating of 65kA@480V, it can safely interrupt the large fault currents found on high-capacity power systems. This is an older Siemens design that is still used in many existing installations, which makes it a useful part for keeping those systems running.
The SHP3B160G05 uses a digital solid-state electronic trip unit instead of a thermal-magnetic one, which gives it precise, repeatable protection. The trip unit provides long-time, instantaneous, and ground fault protection (LIG): long-time protection handles sustained overloads, instantaneous protection responds to short circuits, and ground fault protection detects current leaking to ground, which helps protect equipment and reduce the risk of fires. These functions together make the breaker a strong choice for large feeders and main services where ground fault protection is required.
Mechanically, the SHP3B160G05 is a bolt-on breaker in a molded case, and it is sold without lugs, so the correct lugs must be ordered to match the cable or bus size. At about 71 pounds, it is a large, heavy-duty breaker, so it is worth confirming that it fits your switchgear or enclosure before ordering. This makes the SHP3B160G05 a practical choice for contractors and maintenance teams who need to replace a Siemens SHP breaker in an older system, where a current replacement may not be available.
