Why Choose the TE Connectivity BJMI31.2 2-Pole Jumper Bar 1SNA206053R0700?
The TE Connectivity 1SNA206053R0700, type BJMI31.2, is a heavy-duty 2-pole screw jumper bar designed for compatible ENTRELEC screw-clamp terminal block assemblies. With a 31 mm spacing, it provides a purpose-designed method of electrically bridging two adjacent high-current terminal positions without using a separate interconnecting conductor.
The BJMI31.2 is specified for a substantial 309 A IEC current rating, making it suitable for high-current terminal installations where reliable common-potential distribution is required. Its screw-mounted construction provides a secure electrical connection within the associated terminal system and supports organised, space-efficient panel wiring.
Designed for compatible high-current ENTRELEC terminal blocks including the D150/31 and D10/ZS150 families, the 1SNA206053R0700 has an individual weight of approximately 120 g. The jumper is supplied individually and forms part of the established TE Connectivity / ENTRELEC range of professional terminal block accessories.

Heavy-Duty Two-Pole Bridging for High-Current Terminal Blocks
High-current terminal assemblies often require adjacent connection points to share a common electrical potential. A correctly matched screw jumper bar provides a direct and compact method of making this connection, avoiding the additional space and preparation required for a separate cable link while maintaining an organised terminal installation.
The TE Connectivity BJMI31.2 is engineered specifically for this purpose, providing two-pole bridging at 31 mm spacing with an IEC rating of 309 A. Its screw-mounted construction and specified 3 N·m ± 0.4 N·m tightening torque support a secure connection within compatible ENTRELEC high-current terminal assemblies.
Typical Applications
- High-current industrial terminal block assemblies.
- D150/31 and D10/ZS150 compatible terminal installations.
- Industrial power distribution panels.
- Switchgear and controlgear assemblies.
- Machine and equipment power distribution.
- Electrical control cabinets.
- Common-potential distribution between two high-current terminals.
- Industrial installations requiring heavy-duty terminal bridging.
