It's rated for AC-3 duty up to 440 V at 16 A, which means it handles motor switching (starting, stopping, reversing) for loads like conveyors, pumps, or small fans. The 48 VAC coil keeps control voltage low for safety. Three power poles, all normally open, plus one normally open auxiliary contact for feedback or holding circuits.
Key specs that matter for fit
Mechanically, it's 90 mm wide, 58 mm tall, and 57 mm deep — a compact footprint for a reversing contactor, fitting standard DIN-rail enclosures. It's rated for operation up to 2000 m altitude without derating, and the storage temperature range is -50 to 80 °C. The contactor is also rated for AC-4 utilization (inching, plugging), though at a lower current — the AC-3 16 A figure is the one you'll size the motor circuit by.
