1sna179620r1400 – bjm 12 4 poles
TE Connectivity 1SNA179620R1400 BJM12.4 is a 4-pole, 12 mm pitch screw-mounted cross-connection jumper bar rated at 76 A for compatible Entrelec SNA terminal blocks.
Why Choose the TE Connectivity 1SNA179620R1400 BJM12.4 Jumper Bar?
The TE Connectivity 1SNA179620R1400, also identified as the BJM12.4, is a 4-pole cross-connection jumper bar designed for compatible Entrelec SNA screw terminal blocks. It provides a reliable way to electrically bridge four adjacent terminal positions, simplifying common-potential distribution and reducing individual wiring inside industrial control panels.
The BJM12.4 is designed around a 12 mm modular pitch and is associated with compatible terminal blocks including the M16/12 family. Its screw-mounted construction provides a secure mechanical and electrical connection and makes it suitable for modular DIN rail terminal assemblies used in machinery, automation and power distribution systems.
With 4 bridged contacts and a 76 A rated current, the 1SNA179620R1400 is suited to higher-current cross-connection applications within its compatible terminal system. The jumper is non-insulated and is intended for installation inside appropriately protected electrical equipment.
