Adjustable from 80 to 100 A, Trip Class 10, so it's sized for a motor that's pulling around that FLA range and needs a fast trip on a locked rotor (Class 10 means it trips in under 10 seconds at 7.2x the set current).
Mounts standalone — no DIN-rail clip on this one, so it's screw-fixed to the panel backplate. Dimensions are 140 mm deep, 70 mm wide, 120 mm tall — that 70 mm width is the same as the S3 contactor frame it mates with, so a panel laid out for a 3RT5046 contactor will take this relay without re-spacing. Side clearance to grounded parts needs 6 mm minimum.
The adjustable current range 80-100 A is the headline — set it to the motor's nameplate FLA, and the thermal bimetal element tracks the heating curve. The auxiliary contact circuit draws 1 A at 24 V, 0.22 A at 110 V, 2 A at 230 V — enough for a PLC input or a holding contact, not for direct motor switching.
