Industrial KB220 Two Pole Heavy Duty Circuit Breaker

The Cutler Hammer Westinghouse industrial circuit breaker, Type KB, is a two-pole device rated at 200 amperes. Model KB220 identifies this unit as a 2-pole, 200 A breaker in the KB family, designed to provide overcurrent protection by interrupting current on two hot legs in industrial electrical installations. As a heavy-duty KB series breaker, it is built for rugged service in environments where reliable protection across both conductors is required. The KB line from Cutler-Hammer (Westinghouse) uses the Type KB form factor, offering a compact, two-pole solution that supports protection for two phases while delivering dependable performance under heavy-duty service conditions. This KB220 configuration is specifically the two-pole 200 A variant within the Type KB family for industrial applications that demand solid protection. Two-pole operation ensures simultaneous disconnection of both conductors during a fault, helping to provide safe isolation of affected circuits in demanding industrial settings. With a 200 A rating, this breaker accommodates high-current circuits while delivering reliable interrupting behavior in everyday heavy-duty service.
