Why Choose the TE Connectivity BJDP4 1SNA174781R2500 Cross-Spacing Jumper?
The TE Connectivity BJDP4 1SNA174781R2500 is an industrial cross-spacing jumper designed to electrically bridge compatible terminal blocks with different terminal spacings. Part of the established TE Connectivity Entrelec SNA screw-clamp terminal range, the BJDP4 provides a convenient solution for creating common electrical connections between adjacent terminals where conventional same-pitch jumper bars cannot be used.
Designed as a universal screw jumper bar kit No. IV, the BJDP4 can connect two consecutive compatible terminal blocks with different spacings. This makes it particularly useful in control panels containing mixed terminal sizes, including installations where terminal spacing changes between adjacent blocks. The jumper is specified for a rated main-circuit current of 50 A.
The 1SNA174781R2500 is compatible with a range of Entrelec terminal blocks including D1.5/6.ADO, D4/6.ADO, M2.5/6 and M4/6 variants. Its compact design, approximately 5 g net weight and two-terminal bridging configuration make it a practical accessory for industrial automation, machinery and electrical distribution panels.

Flexible Bridging Between Different Terminal Spacings
Cross-spacing jumpers provide an efficient method of distributing electrical potential between adjacent terminal blocks that do not share the same pitch. This is particularly valuable in industrial panels containing different terminal sizes, where a conventional fixed-spacing jumper may not provide the required connection.
The BJDP4 is designed as a universal screw jumper solution for compatible Entrelec terminal blocks. By providing a dedicated electrical bridge between two consecutive terminals with different spacings, it helps panel builders maintain clean, modular wiring while reducing the need for additional external conductors. Installation of cross-spacing jumpers on applicable terminal arrangements may require the terminal partition to be cut according to the manufacturer's accessory instructions.
Typical Applications
- Bridging terminal blocks with different terminal spacings.
- Industrial electrical control panels.
- Common-potential and power distribution circuits.
- Machine-building and OEM electrical systems.
- Automation and process-control cabinets.
- Maintenance and expansion of compatible Entrelec SNA terminal installations.
