It is rated for 50 A at ≤415 V, with a 48 V coil.
The AC-1 rating of 50 A at ≤415 V governs resistive loads — heaters, incandescent lighting, or resistive banks. That is not a motor-switching rating; for inductive motor loads (AC-3), this contactor would derate significantly. The 48 V coil is a control-circuit voltage, common in older panel designs or low-voltage control schemes. The 4P (4NO) configuration gives four normally-open power poles, which suits single-phase or three-phase resistive circuits where all poles switch simultaneously. Operating altitude is 3000 m, and the protective treatment is TH (pollution degree 3) per IEC 60068 (cite:,).
Mechanical and environmental robustness
The contactor is rated for vibration: 1.5 Gn (5–300 Hz) when open, 3 Gn when closed. Shock ratings: 10 Gn for 11 ms when closed, 6 Gn for 11 ms when open (cite:). These figures mean it holds its contacts under moderate industrial vibration — suitable for panel-mounted use near pumps or conveyors, but not extreme high-G environments.
