Product Description

The MERSEN A70Q Series Semiconductor Fuse (MPN A70Q60-4) is a fast-acting bolt-on fuse rated at 60 A, 700 V AC, and 650 V DC. This AC/DC voltage-type fuse is designed for semiconductor protection in industrial equipment.

Frequently Asked Questions

What is the MERSEN A70Q60-4 semiconductor fuse used for?

The MERSEN A70Q60-4 is a fast-acting bolt-on fuse used to protect semiconductor devices such as diodes, thyristors, and IGBTs in industrial power equipment. It is commonly applied in drives, inverters, and power supplies where rapid overcurrent interruption is critical to prevent damage to sensitive components.

What are the specifications of the MERSEN A70Q60-4 fuse?

The MERSEN A70Q60-4 is a 60 A, fast-acting semiconductor fuse from the A70Q series. It has an AC voltage rating of 700 V and a DC voltage rating of 650 V, making it suitable for AC/DC applications. The bolt-on design ensures secure mounting in industrial fuse holders.

Where to buy the MERSEN A70Q60-4 fuse worldwide?

You can source the MERSEN A70Q60-4 fuse from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide competitive pricing and reliable sourcing for this fast-acting fuse.

How to select the correct MERSEN A70Q60-4 fuse for an application?

To select the correct MERSEN A70Q60-4 fuse, verify that the system voltage does not exceed 700 V AC or 650 V DC and that the continuous current is at or below 60 A. Ensure the bolt-on mounting matches your fuse holder. For semiconductor protection, confirm the fast-acting characteristic matches the inrush current profile of your equipment.
