Glass fuses have a low breaking capacity. It's easy to see when they're blown: the glass will be discolored and the filament broken. Replace yours today!

Ceramic fuses are high or low breaking capacity and can be used in many applications. Ceramic color can vary from a very light beige to dark gray.

Mersen ATM1


Mersen ATM Series Series

Ferraz Shawmut is Mersen. Mersen ATM Amp-Trap midget fuses can be used in a wide range of applications not covered by other midget fuses. Ratings of 30/35, 30/40 and 30/50 amperes are offered for specific applications such as capacitor protection. These ATM fuses must still be considered 30A fuses because of their dimensions, but are able to withstand much higher inrush currents and tougher duty cycles.
