Its AC-3 utilisation category at 400 V delivers 50 A switching capacity — that's the rating that governs motor starting and stopping under full load, not just the resistive AC-1 curve. The 415 V AC coil is a wide-range type, so it holds in across a sagging line without dropping out prematurely.
Compliance and environmental limits
