1sna291324r2000 – 4 pole screwless jumper bar

Why Choose the TE Connectivity 1SNA291324R2000 BJDL10-4 Screwless Jumper Bar?

The TE Connectivity 1SNA291324R2000, type BJDL10-4, is an insulated 4-pole screwless jumper bar designed for reliable common-potential bridging between compatible Entrelec spring clamp terminal blocks. Part of the established SNA terminal block accessory system, this cross-connector provides a convenient way to electrically interconnect four adjacent terminal positions in industrial control panels, machinery and automation installations.

The BJDL10-4 uses a screwless plug-in mounting system with positive locking, helping simplify terminal strip assembly while maintaining a secure electrical connection. Its pre-cut pole configuration eliminates the need to create individual wire links between adjacent terminals, reducing wiring time and helping maintain an organised, space-efficient panel layout.

Designed around a 10 mm spacing, the BJDL10-4 is rated at 24 A and is suitable for compatible DB2.5/10.4L, DH2.5/10.4L, DR2.5/10.4L and DS2.5/10.4L terminal blocks. Its orange insulated construction provides clear visual identification, while the installed terminal arrangement provides IP20 protection at the main terminals.

Reliable Potential Distribution for Industrial Terminal Assemblies

Jumper bars provide an efficient method of distributing a common electrical potential across multiple adjacent terminal blocks. The BJDL10-4 electrically bridges four compatible terminal positions, reducing the need for separate conductor links and helping simplify the construction, inspection and maintenance of terminal strips.

The screwless plug-in design combines straightforward installation with positive locking for a secure assembly. Used with compatible Entrelec spring terminal blocks, the BJDL10-4 provides a clean and integrated solution for distributing power, control voltage or common signal potentials throughout industrial electrical systems.
