3-Pole, UL489 DIN Rail-Mount Miniature Circuit Breakers

6 products
Three-pole miniature circuit breakers protect three circuits from current overloads at the same time. They're UL489 listed for use as branch circuit protection or as supplementary protection from damage caused by short circuits. These circuit breakers follow trip curves to determine when they will interrupt the current. If the current exceeds a device's rating up to a certain factor, the circuit breaker will have a delayed trip to prevent nuisance tripping. If the current exceeds the device's rating at or above that factor, it will immediately trip. They're mounted on standard 35mm DIN rail in low-voltage electrical applications such as control panels, motor control centers, and panelboards.
Curve Type

B-Curve, 3-Pole UL489 DIN Rail-Mount Miniature Circuit Breakers

B-Curve, 3-Pole UL489 DIN Rail-Mount Miniature Circuit Breakers
B-curve three-pole miniature circuit breakers trip instantaneously when the current load exceeds three to five times the rating of the device. These breakers mount on standard 35mm DIN rail and are UL489 listed for use as branch circuit protection or as supplementary protection from damage caused by overcurrents. They protect three circuits at the same time and are used when protection against low-level short circuit faults is desired, such as in PLC wiring, lighting, and appliances.
