Jumpers

Jumpers use the terminal block wire openings. Multi-pole jumpers can be cut into a smaller number of poles. Many 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.

Center Jumpers — Screw Type

These center jumpers are insulated and are available in 2-…50-pole configurations. They mount with screws into the screw type terminal blocks.

Note:The following rules apply when going across different potentials with jumpers cut out.
1. Always de-rate to 400V
2. Always use a partition plate where a cut jumper strip may leave a live end exposed

Center Jumpers — Screwless Type

These center jumpers are insulated and are available in 2-…50-pole configurations. They mount without screws into the both Spring-Clamp terminal blocks and some screw terminal blocks.

Note:When using multiple screwless jumpers in 1492-J3, 1492-J2Q, or 1492-J4 terminal blocks, the following rules apply when going across different potentials with jumpers cut out.
1. When using all 3 channels, or 2 side-by-side channels, de-rate to 125V
2. When using 2 outside channels (leaving the center channel open), de-rate to 400V
3. Always use a partition plate where a cut jumper strip may leave a live end exposed

Center Jumper Covers

Center jumper covers can be used as an extruded marking surface for circuit identification.
