Westinghouse 315C043G15 is a 2-pole molded case circuit breaker from the MA Series, designed to provide thermal-magnetic protection with long-time and instantaneous (LI) trip functions for branch circuits. Rated for 600V AC and 800A continuous current, it delivers a 30kA interrupting capacity at 480V AC for robust fault clearing in single-phase systems. The unit weighs 47 lb and features a bolt-on connection for secure panel mounting, with a compact molded case construction suited for industrial environments. This breaker complies with UL489 standards and National Electrical Code requirements for branch circuit protection in the United States and Canada. Typical applications include motor control centers, HVAC equipment, programmable logic controllers (PLCs), distributed control systems (DCS), and instrumentation panels.
