Product Description

The MERSEN ATDR Series Fuse (MPN ATDR1/4) is a 250 mA, 600 V AC time-delay cylindrical fuse with a dual-element design and melamine body. It is non-indicating, measures 13/32 in x 1 1/2 in, and is intended for branch circuit protection. This fuse is compatible with the USCC fuse block series.

Frequently Asked Questions

What is the MERSEN ATDR1/4 fuse used for?

The MERSEN ATDR1/4 is a 250 mA, 600 V AC time-delay cylindrical fuse designed for branch circuit protection. Its dual-element construction handles temporary inrush currents without nuisance opening, making it suitable for motor and transformer circuits in industrial control panels and power distribution.

What are the specifications of the MERSEN ATDR1/4 fuse?

The MERSEN ATDR1/4 fuse is rated 250 mA at 600 V AC, with a time-delay characteristic and dual-element design. It has a melamine body, is non-indicating, measures 13/32 in x 1 1/2 in, and is compatible with the USCC fuse block series. It is part of the ATDR series for branch circuit protection.

Where to buy MERSEN ATDR1/4 fuses worldwide?

3G Electric supplies the MERSEN ATDR1/4 fuse worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this ATDR series time-delay fuse for branch circuit protection.

How to select the right MERSEN ATDR fuse for branch circuit protection?

To select the correct MERSEN ATDR fuse, match the voltage rating (600 V AC) and current rating (250 mA for ATDR1/4) to your circuit requirements. Ensure the fuse block is compatible with the USCC series. The time-delay dual-element design handles motor start-ups; verify the interrupting rating meets system fault current.
