Product Description

The MERSEN ATQ Series is a time-delay cylindrical fuse, specifically a midget fuse rated at 250 mA and 500 V AC. Measuring 13/32 in x 1 1/2 in, this non-indicating fuse (MPN ATQ1/4) provides overcurrent protection for industrial equipment.

Frequently Asked Questions

What is the MERSEN ATQ Series fuse used for?

The MERSEN ATQ Series time-delay midget fuse (MPN ATQ1/4) provides overcurrent protection for industrial equipment. Its 250 mA, 500 V AC rating suits control circuits, transformers, and motor starters where temporary inrush currents occur. The non-indicating design requires testing to confirm operation.

What are the specifications of the MERSEN ATQ1/4 fuse?

The MERSEN ATQ1/4 is a 250 mA, 500 V AC time-delay midget fuse from the ATQ Series. It measures 13/32 in x 1 1/2 in and is non-indicating. The cylindrical body fits standard midget fuse holders. MERSEN designs these fuses for reliable overcurrent protection in industrial circuits.

Where to buy MERSEN ATQ1/4 fuses worldwide?

3G Electric supplies MERSEN ATQ1/4 fuses worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time. We source genuine MERSEN ATQ Series fuses for industrial overcurrent protection needs.

How to select the correct MERSEN ATQ fuse for an application?

Select the MERSEN ATQ fuse based on voltage (500 V AC max), current rating (250 mA for ATQ1/4), and time-delay characteristics. Ensure the fuse holder accommodates the 13/32 in x 1 1/2 in midget size. For motor or transformer protection, verify the inrush current duration does not exceed the fuse's time-delay curve.
