Why Choose the TE Connectivity BJS5D-20 1SNA177651R0500 20-Pole Jumper Bar?
The TE Connectivity BJS5D-20 1SNA177651R0500 is a 20-pole jumper bar designed for electrical bridging across compatible Entrelec SNA double-deck terminal blocks. With a 5 mm spacing, this conducting accessory provides an efficient method of distributing a common electrical potential across multiple adjacent terminal positions in high-density industrial control and automation assemblies.
Designed for compatible MA2.5/5.D1 and MA2.5/5.D2 terminal blocks, the BJS5D-20 provides bridging across up to 20 terminal positions. The jumper is supplied as a perforated bar without captive screws or spacers and is installed using the appropriate fastening kits, giving panel builders flexibility when configuring the required common-potential connections.
The 1SNA177651R0500 has a rated main-circuit current of 24 A, a 5 mm pitch and a net weight of approximately 3 g. Its compatibility with Entrelec double-deck terminals makes it particularly useful for compact control cabinets where high connection density and efficient potential distribution are required.

High-Density Bridging for Double-Deck Terminal Blocks
Double-deck terminal blocks provide two connection levels within a compact footprint, making them particularly useful where control-panel space is limited. When multiple terminals need to share a common electrical potential, a dedicated jumper bar can reduce external wiring and provide a more organised method of distributing the required connection across the terminal assembly.
The BJS5D-20 provides up to 20 bridged positions at 5 mm spacing for compatible MA2.5/5.D1 and MA2.5/5.D2 terminals. With a 24 A rated current and screw-mounted perforated construction, it provides a practical solution for common-potential distribution in new installations and modifications to existing Entrelec SNA terminal assemblies.
Typical Applications
- Common-potential bridging across compatible double-deck terminal blocks.
- MA2.5/5.D1 and MA2.5/5.D2 terminal assemblies.
- High-density industrial electrical control panels.
- Automation and process-control cabinets.
- Machine-building and OEM electrical systems.
- Maintenance, modification and expansion of compatible Entrelec SNA installations.
