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).

FEATURES/BENEFIT S:

•

For supplemental protection of small motors and transformers

•

Extended ratings for special protection of capacitors and circuits

with high inrush currents

•

600VDC ratings for a wide variety of applications including

photovoltaic and solar applications.

•

Can be used with UltraSafe™ fuse holders

•

1 1/2" x 13/32" (10mm x 38mm) dimensions
