Product Description

The MERSEN SLR Series Fast-Acting Fuse (MPN SLR3) is a cylindrical-body fuse rated at 3 A and 300 V AC. It features integrated insulating caps and is designed for fast-acting overcurrent protection in industrial electrical circuits.

Frequently Asked Questions

What is the MERSEN SLR3 fuse used for?

The MERSEN SLR3 fast-acting fuse provides overcurrent protection in industrial electrical circuits. Its 3 A, 300 V AC rating and integrated insulating caps make it suitable for control panels, power supplies, and equipment requiring rapid response to short circuits or overloads.

What are the specifications of the MERSEN SLR3 fuse?

The MERSEN SLR3 is a cylindrical-body, fast-acting fuse rated at 3 A and 300 V AC. It is part of the SLR series (MPN SLR3) and includes integrated insulating caps for safe handling. The body style is cylindrical, designed for standard fuse holders.

Where to buy MERSEN SLR3 fuses worldwide?
