QC20 - 20Amp Circuit Breaker Description
QC20 - 20Amp Circuit Breaker
The QC20 is a 20 Amp, 2-pole, Type QC plug-on thermal-magnetic circuit breaker intended for you to use in compatible electrical panels that accept QC-style breakers. It provides overcurrent and short-circuit protection on 120/240VAC branch circuits and installs in the existing QC20 breaker position. This product is a new aftermarket replacement made specifically to match the form, fit, and function of the original QC20. No changes to the compatible panel are required when you're replacing an existing QC20. With a 10k A.I.C. interrupting rating and a thermal-magnetic trip mechanism, it is suitable for maintaining existing electrical distribution systems where a QC20 replacement is needed. The breaker is built with durable electrical components for long service life when installed in the proper application.
