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).
Features/Benefits:
• 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
