Protects a circuit against current overloads
Did you know?
WebbThey are often called “circuit breakers for equipment” (CBEs). While both UL 489 breakers and UL 1077 devices protect against both shorts and overloads, UL 1077 devices tend to concentrate more on overloads - largely because they are always down stream of a UL 489 breaker. Short circuits and overloads put different demands on circuit breakers. WebbIf short-circuit should occur, the magnetic action of the circuit breaker will detect the instantaneous values of current and trip the circuit breaker. Fuses usually are not suitable for the protection against overloads , because if sized to provide overload protection , they would blow when the motor starts due to high motor inrush current , although they can …
