It is rated for AC-1 utilisation category — resistive load switching — at 32 A up to 415 V, with a 220 V coil. The 4-pole arrangement with mixed NO/NC contacts makes it suited for applications needing both normally-open and normally-closed power paths in a single device, such as resistive heater banks or lighting circuits where one pole handles the load and another provides a status interlock.
The AC-1 rating of 32 A at ≤415 V is the key selection parameter — this contactor is designed for resistive loads (heaters, incandescent lighting) where inrush current is minimal. It is not rated for motor starting (AC-3) or inductive loads; using it on a motor circuit would exceed its switching capability. The 4-pole configuration with 2NO+2NC means it can simultaneously switch two load circuits and provide two auxiliary interlock signals, all in one 45 mm wide package. The DIN rail mounting support (45 mm width, 74 mm height, 80 mm depth) fits standard enclosure rail — no special adapter needed.
Standards and environmental rating
IP2X finger protection on the enclosure.
Mechanical robustness and switching timing
The contactor is rated for vibration: 1.5 Gn from 5 to 300 Hz when open, 3 Gn when closed. Shock resistance: 7 Gn for 11 ms open, 10 Gn for 11 ms closed.
