Quad Breakers - Eaton Homeline Quad Breakers in San Diego from ESU

At ESU Inc., we keep a large inventory of breakers in stock, including single, double, and quad breakers. A breaker is an essential safety device designed to protect an electrical circuit from damage caused by overload or short circuit. A quad breaker, also called a quadplex breaker, is a four-pole breaker that fits into two slots on a panel, allowing you to save space while safely powering multiple circuits. Popular brands include the Eaton Quad, which offers durability and reliability, and the Homeline Quad, designed by Schneider Electric/Square D for compatibility with Homeline load centers.
