At 5.00 mm, it is wider than a typical signal-level block (3.5 mm or 2.54 mm), which means it is sized for power termination where creepage and wire-bending radius matter.
Wiring and Termination: Screw-Rising Cage Clamp
Wire termination is a screw-rising cage clamp — the screw lifts a clamping plate inside the housing to pinch the stripped conductor against the bus bar. Accepts 16-30 AWG.
Rated 13.5 A per position at 300 V. The 13.5 A figure is the per-contact limit at the rated temperature rise — derate above 105°C ambient.
Ganging and Panel Layout: Side Interlocking
The side interlocking feature lets you snap multiple 282884-3 blocks together into a multi-position assembly without a separate jumper bar or DIN-rail adapter. The interlocking tabs on the housing align the blocks and keep the pitch consistent across the gang. This is useful when your BOM calls for a 6-position or 9-position block and you want to stock a single 3-position variant. The green housing colour is a visual identifier — Buchanan terminal blocks in green are typically the standard unmarked version, as opposed to grey or black for specific wiring schemes.
