Plug In Breakers Bolt On Breakers & Twin Breakers in San Diego from ESU

At ESU Inc., we stock all types of breakers to meet a wide range of applications. A plug-in breaker is designed for quick installation, sliding directly into a panel without the need for additional hardware. A bolt-on breaker offers a more secure connection by fastening directly to the bus bar with a bolt, making it ideal for commercial-grade systems. A twin breaker, also called a tandem breaker, allows two circuits to fit into a single breaker slot, saving valuable space in the electrical panel. No matter your project, we have the right breaker solution in stock—ready to keep your systems safe, efficient, and up to code.
