1sna178026r2700 – 3 deck jumper bar 4 pole

Why Choose the TE Connectivity 1SNA178026R2700 BJD6-4 Jumper Bar?

The TE Connectivity 1SNA178026R2700, also identified as the BJD6-4, is a 4-pole jumper bar designed for cross-connecting compatible Entrelec SNA series terminal blocks. It provides an efficient method of electrically bridging four consecutive terminal positions, reducing separate wiring and helping create compact, organised terminal assemblies in industrial control panels.

The BJD6-4 is designed for compatible D2.5/6.D series multi-level terminal blocks, including D2.5/6.D, D2.5/6.DA, D2.5/6.DAL, D2.5/6.DL and D2.5/6.DP variants. Its perforated screw-jumper construction incorporates captive screws and spacers, allowing unnecessary positions to be removed where the required bridging arrangement calls for it.

Featuring 4 poles, a 6 mm pitch and a 22 A main-circuit rated current, the 1SNA178026R2700 provides a dependable cross-connection solution for multi-level terminal assemblies. Its compact format is well suited to industrial automation, machinery and electrical distribution systems where efficient potential distribution is required.

Key Advantages

• 4-pole jumper bar for cross-connecting four consecutive terminal positions.

• Perforated construction with captive screws and spacers supports flexible bridging arrangements.
• Reduces individual wiring and simplifies industrial control-panel assembly.

Key Features

• TE Connectivity Entrelec SNA series terminal block accessory.
• BJD6-4 4-pole jumper bar.
• 6 mm terminal spacing.
• 22 A main-circuit rated current.
• 4 connected terminal positions.

Efficient Cross-Connection for Multi-Level Terminal Blocks

Multi-level terminal blocks allow several circuits to be accommodated within a compact DIN rail footprint. Purpose-designed jumper bars such as the BJD6-4 enable adjacent terminal positions to share a common electrical potential without requiring individual bridging conductors, helping reduce wiring time and panel complexity.

The 1SNA178026R2700 uses a perforated jumper-bar arrangement with captive screws and spacers. Unnecessary screws and spacers can be removed to configure the required connection pattern, providing flexibility for control, signal and power distribution within compatible Entrelec SNA terminal assemblies.

Typical Applications

• Multi-level and triple-deck terminal block assemblies.
• Industrial control panels and switchboards.
• PLC and automation control cabinets.
• Sensor and actuator wiring systems.
• Machine-building electrical installations.
• Common-potential power, control and signal distribution.
