Medimum and low voltage circuit breakers are commonly separated into the following groups based upon the type of material used to make the frames or cases: Molded case, (MCCB) the most common low voltage type; Insulated case, (ICCB) the intermediate voltage and amperage sizes A two-pole miniature circuit breaker. Four one-pole miniature circuit breakers. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Circuit Breaker Frame Type Maximum Voltage Rating Number ofPoles Cont.

With a huge inventory of used and reconditioned units in stock, we can most easily find what you need. TEY-frame GE molded case circuit breakers are rated up to 125A and interrupt excessive current flows to protect devices from electrical damage. They're typically used with GE light panels, motor control centers, and panelboards. Their current-carrying parts, mechanisms, and trip devices are contained in a molded case. Circuit breakers are divided into types based on their instantaneous tripping current. This is the minimum current at which the circuit breaker will discontinue the flow of electricity, or trip. It does this to protect devices plugged into the circuit from sudden rises in levels of current.

Four one-pole miniature circuit breakers. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Power frequency tests are kept on a new circuit breaker; the test voltage changes with a circuit breaker rated voltage. The test voltage with a frequency between 15-100Hz is applied as follows. (1) between poles with circuit breaker closed (2) between pole and earth with circuit breaker open, and (3) across terminals with circuit breaker open. This type of circuit breaker can be classified as either a manually- or electrically-operated circuit breaker. When a large air circuit breaker is closed, the operating mechanism is latched. As the circuit breaker is closed, a set of tripping springs, or coils, are compressed, and the circuit breaker may then be tripped by means of a trip latch.
