Why Choose the TE Connectivity 1SNA176739R0400 BJMI5D-5 Jumper Bar?
The TE Connectivity 1SNA176739R0400, also identified as the BJMI5D-5, is an insulated 5-pole screw-in jumper bar designed for cross-connecting compatible Entrelec SNA series terminal blocks. It enables five adjacent terminal positions to share a common electrical potential, reducing individual wiring and helping create compact, organised terminal assemblies.
Designed specifically for compatible MA2.5/5.D1 and MA2.5/5.D2 double-deck terminal blocks, the BJMI5D-5 forms part of the SNA screw-clamp terminal accessory system. Its pre-assembled screw connection provides a secure electrical bridge while simplifying installation in industrial control panels and automation equipment.
The BJMI5D-5 provides a 5 mm pitch, 24 A rated current and IP20 protection when correctly assembled. Its insulated, touch-protected construction makes it a dependable accessory for power, control and signal distribution applications using compatible SNA terminal blocks.
