The 2350397-2: It carries a UL rating of 16 A at 300 V, which sets the power ceiling for industrial control panels, lighting, and HVAC equipment where a compact 2-circuit plug is needed. The free-hanging in-line mount and 180° wire entry mean it plugs directly into a mating header or receptacle without panel cutouts. The screwless push-in spring termination accepts 12-26 AWG solid or stranded wire with a 12-13 mm strip length, making field wiring fast — no screwdriver torque, just push the stripped wire into the spring cage.
Why the 16 A / 300 V Rating Matters for Your BOM
At 16 A and 300 V UL, this plug handles typical power distribution for a single-phase load or a pair of signal lines with a common return. The 5.00 mm pitch keeps creepage and clearance sufficient for 300 V in a pollution degree 2 environment — a common requirement for industrial control cabinets. The push-button actuated retention latches on the non-wire side lock the plug into the mating header, preventing disconnection under vibration — a real advantage in machinery with constant cycling.
Termination and Wire Compatibility
The screwless leg spring push-in mechanism accepts wire from 12 AWG (3.31 mm²) down to 26 AWG (0.13 mm²). Strip length is a tight 12-13 mm — consistent stripping is critical for the spring to grip the conductor, not the insulation. The single-level design keeps wiring tidy: each of the 2 positions per level is accessed from the same side.
