HVAC Fuses and HVAC Breakers in San Diego from ESU
At ESU Inc., we supply essential components for every project, including HVAC fuses and HVAC breakers. HVAC fuses are designed to protect heating and cooling systems by breaking the circuit if the current becomes too strong, helping prevent costly equipment damage. HVAC breakers serve a similar purpose but can be reset after tripping, providing reliable protection against electrical overloads. Whether you need standard replacements or specific models, we carry a wide selection to keep your HVAC systems running safely and efficiently.
Our inventory features most of the major brands trusted in the industry, including General Electric, Hammond Power, ITE Siemens, Cutler Hammer, Square D, FPE Federal Pacific, Pushmatic, Zinsco, Crouse Hinds, Challenger, Westinghouse, Sylvania, and Bryant.
