ATM Fast-Acting Midget Fuses

Amp-Trap® midget fast-acting ATM fuses are rated 600 volts AC and DC, with a

100kA interrupting rating. These ratings give the ATM a wide range of applications

not covered by other midget fuses. In addition, 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. (Not for Branch

Circuit Protection).
