Jumper center screw type 3pole grey

Jumpers use the terminal block wire openings. Multi-pole jumpers can be cut into a smaller number of poles. Jumpers carry 100% of rated terminal block current. The back of IEC style jumpers are insulated with plastic. An adjacent partition plate provides the necessary electrical spacings between adjacent jumpers or between exposed ends of cut jumpers. These center jumpers are insulated and are available in 2 to 50 pole configurations. They mount with screws into the screw type terminal blocks.
