It carries a rated operational current of 16 A at up to 440 V in AC-1 utilisation category, with a 220 V AC 50 Hz control coil. The 4 NO pole configuration means all four contacts are normally open, making it a straight fit for switching a resistive load bank or heater circuit where no auxiliary contacts are needed.
The AC-1 category per IEC 60947-4-1 means the contacts are rated for making and breaking currents at unity power factor, so the thermal capacity of the contacts governs the rating, not the arc-quenching capability needed for motor starting. For motor loads you would need an AC-3 rated contactor; this part is specified for resistive loads only. The 220 V AC 50 Hz coil is a wide-range AC control circuit, with a pickup range of 0.7 to 1.25 Uc and a dropout range of 0.3 to 0.6 Uc across -5 to 55 °C. That means it reliably pulls in at 154 V and drops out below 132 V, giving a clean margin for brownout conditions on the control transformer.
Mounts on either a DIN rail or a plate, with a 45 mm width footprint that fits standard 4-module spacing on a DIN rail. The IP20 finger-safe enclosure is fine for enclosed panels but not for washdown environments. Screw clamp terminals accept 1 to 4 mm² flexible or solid wire on the power circuit, and 1 to 4 mm² on the control circuit — standard for panel wiring with ferrule or direct termination.
Certified to EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents. The TH protective treatment per IEC 60068-2-30 means the contactor is treated for tropical humidity environments — useful if the panel ships to a coastal or high-humidity site.
