ESU buys and sells new & used Commercial Circuit Breakers in San Diego.
Electrical Supplies Unlimited (ESU) is your trusted source for high-quality commercial circuit breakers, serving businesses and contractors in need of reliable electrical components. While residential breakers are designed for lower voltage applications, such as homes and small buildings, commercial circuit breakers are built for higher capacity electrical systems, typically found in large offices, industrial buildings, and retail spaces. These breakers provide enhanced durability, greater fault protection, and the ability to handle higher electrical loads. 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 breakers can be difficult, especially when dealing with installations that require supporting hardware. These breakers are commonly installed on panel boards or switchgear cabinets, and since designs change over time, finding compatible hardware can be a challenge. To ensure you get the perfect match, we recommend providing pictures of your installed breakers along with measurements before visiting our store. This helps us identify the closest possible match and saves you time.
