PB-1, PB-2 - fuse disconnectors
Application:
Fuse switch disconnector with fuse insert is designed for protecting against short circuits of transformators and capacitor’s batteries. The main purpose is the protection of distributive devices against the dynamic and heat action of high short circuit currents by limiting the peak current and cutting the power supply in few milliseconds.
Advantages:
- simple design
- small size
- easy to mount
- ability to use typical fuse-links
Construction:
Fuse switch disconnectors are made of electroinsulating plate. The contacts clips are mounted to the plate and they provide mounting the fuse-link. The contact clip consist of three elements: compression spring, contact spring and the terminal.
