1sna176738r0300 – jumper bjmi5d-4pole ip20

Why Choose the TE Connectivity 1SNA176738R0300 BJMI5D-4 Jumper Bar?

The TE Connectivity 1SNA176738R0300, also identified as the BJMI5D-4, is a 4-pole insulated screw jumper bar designed for cross-connecting compatible Entrelec SNA series double-deck terminal blocks. It provides a compact and efficient method of distributing a common electrical potential across adjacent terminal positions while reducing the amount of individual panel wiring required.

Designed for compatible MA2.5/5.D1 and MA2.5/5.D2 terminal blocks, the BJMI5D-4 features a perforated jumper bar with captive screws and spacers. Unnecessary screws and spacers can be removed where required, providing flexibility when configuring cross-connections within modular terminal assemblies.

The jumper provides 4 poles, a 5 mm pitch and a 24 A rated main-circuit current. With IP20 protection when assembled, it is well suited to industrial control panels, automation cabinets and electrical distribution systems where reliable terminal block cross-connection is required.

Key Advantages

• 4-pole jumper bar for efficient cross-connection of adjacent terminal blocks.
• 5 mm pitch matched to compatible SNA double-deck terminals.
• 24 A rated main-circuit current for dependable electrical distribution.
• IP20 protection when correctly assembled.
• Captive screws and spacers simplify installation and handling.
• Perforated construction allows unwanted screw and spacer positions to be removed as required.

Key Features

• TE Connectivity Entrelec SNA series terminal block accessory.
• BJMI5D-4 4-pole jumper bar.
• 5 mm terminal spacing.
• 24 A rated current.
• IP20 degree of protection at the main terminals when assembled.
• Perforated jumper with captive screws and spacers.
• Designed for consecutive terminal block cross-connections.
• Compatible with MA2.5/5.D1 and MA2.5/5.D2 terminal families.

Efficient Cross-Connection for Double-Deck Terminal Blocks

Terminal block jumper bars eliminate the need for separate conductors between terminals that must share the same electrical potential. By connecting several neighbouring terminal positions with one purpose-designed accessory, the BJMI5D-4 helps reduce wiring time, simplify panel layouts and maintain an organised terminal assembly.

The 1SNA176738R0300 is specifically designed for compatible SNA double-deck terminal blocks. Its four-pole configuration and captive screw system provide a secure mechanical and electrical connection, while the removable screw and spacer arrangement gives panel builders additional flexibility when creating the required cross-connection pattern.

Typical Applications

• Industrial control panels and switchboards.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Double-deck terminal block assemblies.
• Common-potential power and signal distribution.
• Process control and instrumentation panels.
