Product Description

The MERSEN GSF Series is a time-delay cylindrical fuse rated at 2 A and 250 V AC, with a non-indicating 5 mm x 20 mm body. It is equivalent to the S505, 477, and GSF fuse series and carries the manufacturer part number GSF2.

Frequently Asked Questions

What is the MERSEN GSF2 fuse used for?

The MERSEN GSF2 is a 2 A, 250 V AC time-delay cylindrical fuse used to protect circuits against overcurrents while tolerating temporary inrush spikes. It is commonly applied in industrial control panels, power supplies, and instrumentation where reliable, delayed-opening protection is required.

What are the specifications of the MERSEN GSF2 fuse?

The MERSEN GSF2 is rated 2 A at 250 V AC, with a time-delay characteristic and a non-indicating 5 mm x 20 mm body. It belongs to the GSF series and is equivalent to S505, 477, and GSF fuse series. The manufacturer part number is GSF2.

Where to buy MERSEN GSF2 fuses worldwide?
