Panel Wiring Terminal Block, 2 Positions, 5.08 mm Pitch
The 1776493-2: This is a single-level block — each position terminates one wire, and the 2-position count matches the most common starting point for a multi-pole terminal strip. Rated 10 A at 300 V, the block handles control-circuit power and signal wiring typical in panel building, lighting ballasts, and building automation. The 14-22 AWG wire range accepts solid or stranded copper — the leaf-spring wire guard under the M2.6 screw prevents conductor damage during termination. Specified torque is 0.4 Nm (3.5 Lb-In), giving a repeatable clamp force that field techs can verify with a torque driver.
Interlocking Side Feature for Multi-Pole Ganging
The Interlocking (Side) feature lets you mechanically link multiple 1776493-2 blocks side-by-side to form a wider terminal strip without a separate jumper or bracket. Each 2-position block snaps into the next, creating a continuous assembly that shares the same pitch and board footprint. This is a practical detail for a 4-, 6-, or 8-position run on a PCB — you order the 2-position blocks and gang them, rather than sourcing a single wide part.
Wire termination is screw - leaf spring, wire guard — the screw bears on a stainless steel leaf spring that presses the wire against the current bar, with a wire guard to prevent the screw from twisting or damaging strands. The clamp material is steel, stainless; the screw is steel, galvanized - chromate plated. Contact material is brass - copper tin plated, adequate for the 10 A rating and the expected number of re-terminations in a panel environment.
