Why Choose the TE Connectivity SC-JB8-5 Short Circuit Bridge?
The TE Connectivity SC-JB8-5 (1SNK900655R0000) is a yellow 3 / 5-pole short circuit bridge designed as a conducting accessory for compatible ENTRELEC SNK Series terminal block assemblies. It provides a practical means of electrically bridging multiple terminal positions, making it suitable for common-potential distribution and circuit interconnection in industrial control panels, machinery and automation equipment.
Designed around an 8 mm terminal spacing, the SC-JB8-5 provides selectable 3- or 5-pole bridging capability. Its compact construction allows several adjacent terminal positions to be interconnected efficiently, helping simplify panel wiring and reduce the need for individual jumper wires.
The bridge has an IEC current rating of 5 A and a maximum contact current rating of 5 A. Its yellow polyamide housing provides clear visual identification, while an operating temperature range of -55 to 110 °C and IP20 protection support reliable use in industrial electrical environments.
