BA511 Moulded case circuit breakers
BA511 moulded case circuit breakers and switch-disconnectors are intended for protecting electrical equipment from 10 A to 1000 A and are sometimes used also for switching. They are suited to less demanding operations. These are delivered from the factory fully assembled in accordance with the order’s specifications. These circuit breakers can be used to replace some older circuit breakers (J2UX or J21U, for example) without needing to modify the switchgear.
