OJ7/J is an over-barrier jumper connector designed for use with Magnum LP3000 series single-row terminal blocks. This jumper is specifically configured to bridge adjacent poles within the terminal block assembly, enabling simplified wire management and reducing the need for external jumper wires. The OJ7/J operates within the LP3000 series electrical ratings of 30A at 150V, with a center spacing of 0.437 inches (11.10 mm) and compatibility with #12-22 AWG wire ranges. The jumper is molded from black UL-rated 94V0 thermoplastic material, matching the base terminal block construction for consistent performance and reliability. This component is commonly used in industrial control panels, power distribution systems, and electronic equipment where compact, reliable interconnections between adjacent terminal positions are required.
