Why Choose the TE Connectivity 1SNA179621R0100 BJM12 5-Pole Jumper Bar?
The TE Connectivity 1SNA179621R0100, also identified as the BJM12, is a 5-pole cross-connection jumper bar designed for compatible Entrelec SNA screw terminal blocks. It provides a simple and reliable way to electrically bridge five adjacent terminal positions, reducing individual wiring and supporting neat common-potential distribution in industrial control panels.
Designed for the SNA screw terminal system, the BJM12 uses a 12 mm modular pitch and connects 5 terminals through a single transverse connector. Its non-insulated construction is intended for installation inside suitably protected electrical assemblies where secure screw-terminal cross-connections are required.
With a rated current of 76 A and a rated voltage of 800 V, the 1SNA179621R0100 is suitable for demanding industrial distribution and automation applications. Its compact cross-connection format helps simplify panel wiring while maintaining dependable electrical continuity between compatible terminal blocks.
