Circuit Breakers & Protection

Single-pole, 2-pole and tandem circuit breakers from 15 A to 100 A, GFCI breakers and loadcenter parts from Square D, Eaton, Connecticut Electric and Siemens. Part of our lighting and electrical supplies; see the lighting and electrical buying guide.

Breakers are listed by brand and type, amperage and poles. A breaker has to match the panel it goes in, such as Square D HomeLine, GE Q-Line, or Zinsco and UBIP replacements from Connecticut Electric, so check the panel label before ordering. GFCI breakers, loadcenters and hubs are listed alongside. See Electrical Boxes, Conduit & Fittings.
