Terminal Block Accessories

A variety of accessories adds to the versatility of terminal blocks. They expand terminal block capabilities and facilitate circuit maintenance.

DIN Terminal Block

Example

Application

DIN Rail

Figure 29.

Enables snap-in/snap-out component mounting. Available in 35 mm, 32 mm, and 15 mm widths. Steel or aluminum, Slotted or solid.

End Stop

Figure 30.

Holds blocks and prevents them from shifting position or sliding off the rail.

End Plate

Figure 31.

Covers exposed contact block side or end block of an assembly. Should also be used when a change in block sizes occurs. Has exact same shape/contour as block.

Partition Plate

Figure 32.

Attached to block. Snap-in version available. Provides electrical and visual separation of adjacent terminal blocks and bridges. Also used between blocks of different polarity or voltages.

Cross Connectors

Figure 33.

Connect adjacent terminal blocks. Available in various pole configurations with or without insulation.

Rapid Mounting Tool

Figure 34.

Picks up ten blocks at one time, greatly reducing installation time.

Dead Front Cover

Figure 35.

A protective insulated cover on a terminal block that prevents shocks or shorts. Regulation VDE 0113 requires a cover on all main line blocks that remain live after main switch is off. The covers are removable only with a tool.

Switchable Connecting Link

Figure 36.

Provides easy, temporary connection of two adjacent blocks for maintenance and testing. The link screws directly into the current carrying bar.

Marking Tags

Figure 37.

Enable fast and easy identification of terminations. These easy-to-read labels mount on the side or top face of the terminal block body.

Jumper Comb

Figure 38.

Provides common connection of adjacent blocks. Individual jumper connections may be removed to skip over terminal blocks. The jumper comb is inserted with the wire into the wire cage. Comb jumpers are available in insulated and uninsulated form.

Test Plug

Figure 39.

Provides an electrical connection that permits accurate testing of circuits when necessary. A socket mounts in top of terminal block, providing a receptacle for the test plug.

Plotter

Figure 40.

Provides the end user the capability to custom mark blank tags for identifying terminal blocks, connectors wires and switching devices.

Ferrules

Figure 41.

Are used to capture the stranded ends of wire to provide protection to the wire and an electrically sound connection with all types of clamping bodies.
