Screw Clamp Sliding Link and Shorting Terminal Blocks
The SCB family of DIN rail mounted sliding link terminal blocks and current transformer shorting terminal blocks are designed for modularity, reliability and safety. Wires are connected to the shorting type terminal block using the tested screw clamp wire termination technology. The sliding 2 or 4 position jumper is ideal for single and three phase circuits that are wired to a current transformer where it is necessary to short out the secondary winding during installation, maintenance or testing. Since current transformers should never be open-circuited when current can pass through it is necessary to use a specially designed terminal block such as the SCB series which performs both the open circuit and short circuit function in one device. The SCB series of sliding link terminal blocks perform its functions by:
Sliding link terminal blocks perform the function of opening the CT secondary circuit for test and maintenance purposes. Anti-loosening of the sliding link is accomplished with the locking screw.
Shorting jumper is used to short the secondary circuit of the current transformer for test and maintenance purposes. Anti-loosening of the jumper is accomplished with the screw which is part of the color coded test sockets
The diagrams below and the illustration show the components and shorting terminal blocks and jumpers in typical industrial power applications.

The bench-top DIN rail cutter from ASI quickly cuts all major types of DIN rail, comes with a steel rule measuring device for setting up multiple cuts of the same length and features a hardened steel cutting die for long life. It cuts the DIN rail clean so burrs are eliminated and the long actuation lever insures that anyone can cut the DIN rail. It is half the price of comparable DIN rail cutters now on the market.
