The 282837-6: It uses a screw-rising cage clamp termination — the screw tightens a clamp that pulls the wire against a current bar, giving a gas-tight connection that resists loosening from vibration. The green polyamide 6/6 housing carries a side interlocking feature so you can key several blocks together into a multi-position strip without extra brackets.
Sizing the Wire and the Termination Torque
The clamp accepts 16-28 AWG solid or stranded wire — the 16 AWG end is the practical limit for the 13.5 A rating without excessive temperature rise. The M3 screw has a specified torque of 0.68 Nm (6 Lb-In). Over-torquing can strip the brass threads or crack the nylon housing; under-torquing leaves a high-resistance joint that heats under load. The brass clamp and screw are nickel-plated to resist corrosion in humid cabinet environments.
Mating Orientation and Board Layout
The wire entry is horizontal with the board — the screw axis is parallel to the PCB, so the block sits low and the wires exit sideways. Through-hole mounting with 0.200" pitch means the PCB footprint needs a row of holes on that spacing; the side interlocking tabs let you align multiple blocks end-to-end without gaps. The single-level design keeps the board height minimal — useful when the terminal block sits near an enclosure lid.
