1SNA205500R1000 – PCMS-4-RD

Why Choose the TE Connectivity 1SNA205500R1000 PCMS-4-RD Red 4-Pole Comb Jumper?

The TE Connectivity 1SNA205500R1000, also known as the PCMS-4-RD, is a red 4-pole comb-type jumper designed for compatible Entrelec terminal block assemblies. It provides a purpose-designed method of electrically connecting four adjacent terminal blocks, allowing them to share a common electrical potential without installing individual jumper wires between each position.

Part of the PCMS comb jumper range, the 1SNA205500R1000 is the red four-pole version of a modular cross-connection system capable of bridging compatible terminal blocks. Its four-pole configuration makes it particularly useful where a common supply, signal or other electrical potential needs to be distributed across four adjacent connection points within an industrial control panel.

The PCMS-4-RD features red UL94 V-0 insulating material, providing clear visual identification of the bridged potential while supporting professional panel construction. Supplied in a standard pack of 20 pieces, it is a practical terminal accessory for automation equipment, interface assemblies, machinery and industrial electrical cabinets.

Key Advantages

• Provides simultaneous electrical cross-connection across four compatible terminal blocks.
• Red colour provides clear visual identification within terminal assemblies.
• Reduces the need for individual jumper conductors between adjacent terminals.
• Helps simplify common-potential distribution in industrial control panels.

Efficient Four-Pole Cross-Connection with PCMS Comb Jumpers

PCMS comb jumpers are designed to electrically connect multiple compatible terminal blocks without requiring separate jumper wires between each position. The PCMS family includes different pole counts and colour variants, allowing panel builders to select a jumper that matches both the required number of connections and the desired visual identification. The PCMS-4-RD provides a dedicated four-pole red cross-connection.

Using a purpose-designed comb jumper can reduce wiring effort and help produce a cleaner, more organised terminal assembly. The red colour also makes the cross-connection easier to identify during installation, inspection and maintenance, making the 1SNA205500R1000 particularly useful in industrial control panels and automation systems where clear potential identification is important.

Typical Applications

• Industrial electrical control panels.
• Four-pole common-potential distribution.
• Cross-connection of compatible Entrelec terminal blocks.
• PLC and automation interface panels.
• Machine building and OEM electrical systems.
• Factory automation equipment.
• Process control and instrumentation cabinets.
• Terminal assemblies requiring colour-coded multi-pole bridging.
