Fuses are relatively inexpensive and fairly simple devices. It is their behavior or function that is more complex than most people know. The fuse is considered the weak link in an electrical circuit because it is this vital component which will protect many meters of electric cable and/or costly equipment against faults. The element is the most important component of the fuse and the Limtiron® fuse’s element is made of copper, a high conductivity material. This fuse is a bolt mount, 5 second time-delay minimum at 500 percent rated current, 600 Vac or less voltage rating. |
- A great, economical solution for high fault circuits
- Copper element provides a minimum 5 second time-delay at 500% ampere rating
- 200,000 AIR complies with NEC Sections 110-9 and 230-65 in today’s large capacity systems
- Unique dimensions prevent accidental replacement by other fuse classes
- Glass melamine body and plated terminals provide superior reliability in harsh environments
- One year manufacturer warranty
Typical Applications:
- Large distribution switchboards
- Power Panel boards
- Large machinery disconnects
