SHP3B160

The SHP3B160 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 SHP3B160 uses a digital solid-state electronic trip unit instead of a thermal-magnetic one, which gives it precise, repeatable protection against overloads and short circuits. Solid-state trip units measure current electronically, so the breaker’s response is consistent and does not depend as heavily on temperature as a thermal element does. This makes the breaker a strong choice for large feeders and main services where dependable protection matters. Mechanically, the SHP3B160 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 roughly 70 pounds, it is a large, heavy-duty breaker, so it is worth confirming that it fits your switchgear or enclosure, and checking the trip functions against your equipment, before ordering. This makes the SHP3B160 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.
