AMP-TRAP
®
ATM
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).
