Why Choose the TE Connectivity 1SNA173453R2300 BJH18-3 Jumper Bar?

The TE Connectivity 1SNA173453R2300 is a BJH18-3 3-pole jumper bar designed to electrically interconnect consecutive compatible stud terminal blocks in industrial and railway electrical assemblies. Part of the established TE Connectivity Entrelec terminal block accessory range, it provides a practical method of distributing a common electrical potential across three neighbouring terminal positions.

The BJH18-3 is a perforated, non-assembled screw jumper bar featuring 18 mm spacing. It is designed for compatible Entrelec stud terminal blocks and is installed beneath the washer and nut of each terminal, providing a secure and space-efficient alternative to individual interconnection wires.

With its 3-pole configuration, the 1SNA173453R2300 bridges three consecutive terminal positions. It is particularly suited to compatible HD16/14.FF5.21 stud terminal block assemblies where 18 mm jumpering pitch is required using the appropriate spacer or circuit-separation arrangement.

Key Advantages

• Purpose-designed 3-pole jumper bar for stud terminal blocks.
• 18 mm spacing for compatible Entrelec terminal assemblies.
• Connects three consecutive terminal positions to a common potential.
• Perforated jumper construction enables straightforward screw-mounted installation.
• Reduces the need for separate interconnecting wires within electrical panels.
• Designed for compatible HD16/14.FF5.21 stud terminal block systems.

Key Features

• TE Connectivity Entrelec BJH series.
• BJH18-3 jumper bar type.
• 3-pole / 3-way configuration.
• 18 mm connection spacing.
• Perforated jumper bar without captive screws or washers.
• Designed to fit beneath the terminal washer and nut.
• Suitable for compatible stud terminal block assemblies.
• Product weight approximately 9.9 g.

Reliable Interconnection for Stud Terminal Blocks

Jumper bars provide an efficient way to electrically common adjacent terminal blocks without installing separate wire links between each terminal. This can simplify panel wiring, reduce installation time and maintain a cleaner, more consistent terminal assembly in industrial electrical equipment.

The TE Connectivity BJH18-3 is designed specifically for 18 mm pitch jumpering applications. The perforated bar is positioned beneath the washer and nut of each compatible stud terminal, creating a secure interconnection across three consecutive positions while retaining the modular construction of the terminal assembly.

Typical Applications

• Industrial control panel terminal assemblies.
• Railway electrical and control systems.
• Stud terminal block interconnections.
• Power distribution and switchgear assemblies.
• Machine building and OEM electrical systems.
• Common-potential distribution across consecutive terminals.
