Why Contractors Specify Eaton

Bussmann fuses are one of the most widely stocked fuse brands in HVAC wholesale distribution with HVAC-specific time-delay fuse types for compressor startup inrush protection. Eaton safety switches cover the amperage ratings specified by most residential and commercial HVAC equipment manufacturers.

How to Choose an Eaton Product

For fuses, match the fuse type and amperage to the equipment nameplate MOCP specification; use a dual-element time-delay fuse for compressor circuits. For safety switches, match the switch amperage to the equipment nameplate disconnect specification.
