JB2-02/J is a jumper bar hardware option designed for use with A2 and LP2 series single row terminal blocks. This 2-pole jumper provides electrical connection between adjacent terminal positions, featuring a height of 0.33" (8.4mm). The jumper is compatible with terminal blocks rated for 30A at 300V (A2) or 150V (LP2), with wire range of #12-22 AWG Cu and operating temperature range of -40°C to 105°C. It is commonly used in applications requiring multiple terminals to share a common electrical connection, simplifying wiring and improving reliability in PCB-mounted terminal block assemblies.
