Bussmann MDL-40 Small-Dimension Time-Delay Fuse, Eaton Bussmann Series

Bussmann MDL-40 Small-Dimension Time-Delay Fuse, Eaton Bussmann Series

The Bussmann MDL-40 is a time-delay fuse from the Eaton Bussmann series, built in a small-dimension form factor for use in compact panelboards, enclosures, and control cabinets where space is at a premium. As a time-delay device, the MDL-40 is designed to ride through brief, harmless current surges—such as the inrush associated with motor starting or transformer energization—without nuisance opening, while still responding promptly to sustained overload conditions to help protect downstream wiring and equipment. Carrying the Eaton Bussmann name, the MDL-40 gives electrical contractors and maintenance teams a familiar, dependable option when specifying overcurrent protection for small-format fuse applications. Fuses in the Eaton Bussmann series are commonly specified by electrical professionals for consistent, code-compliant overcurrent protection across a wide range of applications.
