Product Description

The MERSEN A4BY Series Class L Time-Delay Bolt-On Fuse (MPN A4BY1600) is a 1.6 kA, 600 V AC, 300 V DC industrial fuse with a bolt-on body. This time-delay fuse is designed for overcurrent protection in electrical circuits.

Frequently Asked Questions

What is the MERSEN A4BY1600 fuse used for?

The MERSEN A4BY1600 is a Class L time-delay bolt-on fuse rated 1.6 kA, 600 V AC, 300 V DC. It provides overcurrent protection in industrial electrical circuits, such as feeders, switchboards, and motor control centers, where high interrupting capacity and delayed response to inrush currents are required.

What are the specifications of the MERSEN A4BY1600 fuse?

The MERSEN A4BY1600 is a Class L, A4BY Series, bolt-on body, time-delay fuse. Key specs: 1.6 kA current rating, 600 V AC, 300 V DC. It is designed for high-current industrial overcurrent protection with a bolt-on mounting style for secure installation in fuse holders or disconnects.

Where to buy the MERSEN A4BY1600 fuse worldwide?

3G Electric supplies the MERSEN A4BY1600 fuse to customers worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this Class L time-delay fuse.

How to select the correct MERSEN A4BY1600 fuse for an application?

To select the MERSEN A4BY1600, verify your circuit voltage (600 V AC or 300 V DC max) and continuous current (1.6 kA). Ensure the bolt-on body matches your fuse holder. The time-delay characteristic handles motor inrush; confirm coordination with upstream and downstream protective devices per NEC or IEC guidelines.
