Description
The Westinghouse JB3175S is a robust 3-pole molded case circuit breaker designed for industrial and commercial electrical distribution systems. Rated at 175 amps continuous with a 600 VAC maximum voltage, it features an adjustable thermal-magnetic trip unit that provides overload and short-circuit protection, with magnetic trip settings ranging from 875 to 1750 amps. This model includes a 120 VAC shunt trip for remote tripping capabilities and a 1A-1B auxiliary switch rated at 480 VAC for status indication or interlocking. Ideal for applications in motor control centers, panelboards, and switchgear, it offers reliable protection against electrical faults while ensuring minimal downtime. Advantages include its compact design for easy installation, high interrupting capacity (typically 22 kA at 480V, based on similar models), and durability in harsh environments. Drawbacks may include obsolescence since Westinghouse breakers are now supported by Eaton, potentially limiting parts availability, and the need for periodic testing in used units. Compared to modern equivalents like Eaton's Series C, it provides cost-effective retrofitting for legacy systems but may lack advanced digital features.
