It carries an AC-3 rating of 12 A at up to 440 V, with a 440 V AC coil — the utilisation category that governs its real-world motor-switching capability, not just the resistive AC-1 curve. The contactor is certified to EN/IEC 60947-1, -4-1, and -5-1, plus the corresponding GB/T standards, and passes the 850 °C glow-wire test per IEC 60695-2-1. It carries IP2X finger protection and TH protective treatment for pollution degree 3 environments.
The 1.5 ms non-overlap time between NC and NO contacts on both energisation and de-energisation ensures break-before-make operation in safety-related control circuits. Rated for operation up to 3000 m without derating, and ambient temperatures from -20 to 70 °C at the coil (with a -60 to 80 °C storage range). The vibration and shock ratings — 1.5 Gn open, 3 Gn closed, and 7/10 Gn shock — confirm it holds contact under moderate industrial mechanical stress.
