QC50 - 50Amp Circuit Breaker Description
QC50 - 50Amp Circuit Breaker
The QC50 is a 50-amp, 2-pole plug-on thermal-magnetic circuit breaker designed for use in your compatible QC series panels. This aftermarket replacement fits the same mounting location as the original QC50 and carries a 120/240VAC rating with a 10k A I.C. interrupting capacity.
Its thermal-magnetic trip unit responds to both overloads and short circuits, providing branch-circuit protection in residential and light-commercial electrical systems. The plug-on design allows the breaker to install in compatible load centers without modifying the existing panel. Before replacing any circuit breaker, verify that the panel requires a QC-type breaker with matching electrical ratings.
