Reliable Protection for Electrical Distribution Systems
The Mersen BTIA55V20 operates by interrupting excessive electrical current before it can cause serious damage to cables, switchgear or connected equipment. During an overload or short circuit, the internal fuse element disconnects the affected circuit and limits the amount of damaging fault energy allowed to pass.
Its gG operating characteristic provides protection across the complete current range, making the fuse suitable for panel builders, electrical contractors and maintenance engineers working with industrial machinery, control equipment and commercial power distribution systems.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- Low-voltage switchgear.
- Fuse switches and switch disconnectors.
- Industrial machinery and automation equipment.
- Cable, conductor and equipment protection.
