Electrical Supplies Unlimited (ESU) is your trusted source for high-quality commercial circuit breakers, serving businesses and contractors in need of reliable electrical components.

At ESU, we carry a wide selection of commercial circuit breakers to meet the needs of your project, ensuring safety and compliance with electrical codes.
Commercial circuit breakers can be challenging to work with, especially when installations require specific supporting hardware. These breakers are typically mounted on panel boards or inside switchgear cabinets, and because equipment designs evolve over time, locating compatible hardware can be tricky. To ensure you get the best match for your system, Electrical Supplies Unlimited recommends bringing photos and measurements of your installed breakers before visiting our San Diego store.
