10-position plug for Buchanan terminal blocks
The 1-1776263-0: Rated 10 A at 300 V, it accepts 16-24 AWG (0.2-1.4 mm²) wire terminated via a screw clamp with leaf spring and wire guard; the tin-plated brass contacts suit moderate-cycle industrial service.
Side-interlocking for multi-level builds
The 1-1776263-0 carries a side-interlocking feature that allows multiple plugs to be keyed together side-by-side, building a wider multi-circuit assembly while keeping each 10-position block individually serviceable.
