What This 12-Position Terminal Block Delivers
The 1-796690-2: That current rating is the headline number for this class of screw-clamp block — it carries the full load of a power distribution point on the board, not a signal line. The wire termination uses a screw rising-cage clamp — an M3 screw torqued to 0.79 Nm (7.0 Lb-In) pulls the clamp up against the conductor. The clamp material is brass with tin plating; the screw is brass with nickel plating. The contact material is brass with tin plating. This is a field-proven termination for solid and stranded wire in panel and control cabinet wiring. The housing is polyamide (PA66) in green, a single-level design with 12 positions. The side interlocking feature (Interlocking (Side)) allows multiple blocks to be ganged together side-by-side to create a multi-position assembly — common in control panels where the circuit count exceeds 12 and a continuous terminal strip is desired.
Wiring and Torque: What the Screw-Clamp Specs Mean
The wire gauge range is 12-30 AWG — that covers most control-circuit and power-distribution wiring. The M3 screw with a specified torque of 0.79 Nm (7.0 Lb-In) is the correct setting for the rising cage clamp. Over-torquing strips the brass threads or damages the conductor; under-torquing leaves a high-resistance joint that heats under load. Use a calibrated torque driver set to that value. The screw is brass with nickel plating, which prevents galling during repeated terminations. The contact material is brass with tin plating, matching the clamp for galvanic compatibility.
