It's rated for AC-3 and AC-4 duty, meaning it's built for starting and plug-reversing squirrel-cage motors — the AC-3 figure of 16 A at 440 V is the one that governs motor switching, not the resistive AC-1 rating. The coil pulls in at 127 V AC, which is common in North American control transformers stepping down from 480 V.
Fit and integration notes
It measures 90 mm wide by 58 mm high by 57 mm deep — that 57 mm depth is the dimension to watch when you're laying out the DIN rail against the gland plate or a shallow enclosure door. It's rated for -25 to 50 °C ambient operation, which covers most indoor panel conditions but not a hot rooftop cabinet in direct sun.
