4A 250V Glass Fuse 6x30 mm

 6x30 glass fuses are medium-sized cylindrical fuses used to provide protection in electrical circuits against overcurrent conditions. They are named after their dimensions: 6 mm diameter and 30 mm length. Thanks to the clear glass body, the fuse’s status can be easily visually inspected. The internal melting wire or strip breaks the circuit by melting when the current exceeds a specified limit, protecting the devices from damage.

General Features:
