Overview

The Mersen ATM30/40 Amp-Trap® fuse is a fast-acting midget fuse designed for supplemental protection of small motors, transformers, and circuits with high inrush currents. Rated for 600 volts AC and DC, this fuse delivers a 100kA interrupting rating, enabling reliable performance in demanding applications beyond standard midget fuses. The 30/40 ampere rating is engineered for capacitor protection, where it withstands significantly higher inrush currents and tougher duty cycles while maintaining the 30A dimensional profile. The ATM30/40 is not intended for branch circuit protection. With dimensions of 1 1/2" x 13/32" (10mm x 38mm), this fuse is UL listed to Standard 248-14 and CSA certified to Standard C22.2 No. 248.14. It is also DC listed to UL Standard 248-14. Compatible with Mersen's UltraSafe™ fuse holders, the ATM30/40 ensures enhanced safety and ease of use. Its fast-acting nature provides quick response to overcurrent events, safeguarding sensitive equipment. The 600VDC rating makes it suitable for photovoltaic and solar applications.
