£10.20
The TE Connectivity PC8-R4 1SNA400724R0300 is a 4-pole jumper bar from the ENTRELEC SNA terminal block range, designed to electrically bridge compatible terminal blocks and distribute a common potential across multiple connection points. It provides a compact and purpose-designed alternative to installing individual linking wires within DIN rail terminal assemblies.
Designed around 8 mm terminal spacing, the PC8-R4 has a maximum contact current rating of 70 A. Its four-pole configuration is particularly useful where a smaller group of adjacent terminals needs to be commoned while retaining an organised and serviceable panel layout.
The PC8-R4 features a black construction, weighs approximately 4.5 g and is specified for operation from -55 to +110 °C. As an original TE Connectivity ENTRELEC conducting accessory, it is engineered for integration with appropriate SNA terminal block assemblies.
Jumper bars simplify terminal-strip wiring by electrically connecting selected adjacent terminals without requiring separate conductors between every connection point. This can reduce wiring effort, improve panel organisation and make common-potential distribution easier to identify during commissioning and maintenance.
The PC8-R4 is specifically configured with 4 poles and 8 mm spacing. Its 70 A maximum contact current rating and broad operating-temperature range make it a robust bridging accessory for compatible ENTRELEC SNA terminal assemblies in industrial electrical installations.
