Plug In Miniature Circuit Breakers
Miniature circuit breakers are designed for cutting off an electrical circuit to provide protection during overload and faulty conditions. These units can be plugged in into a compatible distribution board. Raptor Supplies offers a wide range of these plug-in circuit breakers from brands like Challenger, Eaton, FPE, General Electric, Murray, Siemens and Square D. Square D miniature circuit breakers (MCBs) feature a thermal-magnetic trip unit, calibrated at 40 Degrees C, providing both time-delay and instantaneous current limiting functions. These breakers are equipped with a Visi-Trip indicator to display the tripped status and are available in 1, 2 and 3 pole options with a maximum interrupting capacity of 5kA at 480 VDC. Eaton plug-on miniature circuit breakers are suitable for interrupting short circuit occurrences in a branch circuit and feeder systems. They are snapped in one place and inserted in sections of panelboards that are then connected directly with the built-in bus bars, thus reducing the additional need of pigtail wires.
