Key Features
Fast-Acting Overcurrent Protection
A fast-acting fuse is designed to interrupt excessive current without the intentional delay of a time-delay fuse. Choose this characteristic only when it meets the protected equipment manufacturer’s requirements.
Compact 5 × 20 mm Format
The miniature cartridge size is suitable for compatible fuse holders and equipment. Confirm both the length and diameter before ordering a replacement.
Transparent Glass Construction
The glass body allows visual inspection of the fuse element, although visual appearance alone cannot establish whether a fuse is electrically functional.
Typical Applications
Depending on its confirmed electrical ratings, a 5 × 20 mm glass fuse may be used in:
– Electronic equipment
– Instrumentation and measuring devices
– Compatible power supplies
– Electrical control circuits
– Appliances and other equipment designed for miniature cartridge fuses
