Panel-Mount Barrier Block for Fixed Power Wiring
The 1546306-4: It accepts wire from 12 AWG down to 22 AWG, terminated by nickel-plated steel screws onto a closed bottom — the screw clamps directly on the stripped conductor, not a through-hole bus bar. A flange on each end lets you bolt the block to a chassis or enclosure panel for a fixed, non-pluggable power distribution point.
Wire Range and Termination — What Fits Under the Screw
The 12-22 AWG range covers both the incoming power feed and the control or tap circuits. The closed bottom means the stripped wire sits on the housing floor, and the screw bears down on the conductor.
Mounting and Environment — Where This Block Goes
The flange on each end takes a screw (not included) to bolt the block to a panel, chassis, or DIN-rail adapter plate. The UL94 V-0 rating means the thermoplastic housing will not sustain a flame inside the equipment.
