The 45 mm width and 85 mm height fit the standard S0 footprint, and the 91 mm depth leaves room for wiring in a typical 200 mm deep enclosure. Side-by-side mounting is allowed with no additional gap, saving rail space.
Rated at 11 kW for AC-2 duty at 400 V, this contactor handles slip-ring motor starting and stopping. For reversing or plugging duty (AC-4), it's rated at 15.5 A at 400 V — that's the current it can interrupt during frequent reversals, which is the more demanding rating for applications like crane hoists or conveyor reversers. The AC-12 rating of 10 A covers resistive and solid-state loads in control circuits. For DC switching, the contactor is rated at 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the maximum currents it can break in DC circuits, where arcing is harder to extinguish than in AC. Type 2 coordination (no-weld) requires a 35 A gL/gG fuse upstream; Type 1 coordination (welding allowed but no fire risk) allows a 100 A gL/gG fuse.
Main circuit terminals are screw-type, accepting solid conductors from 2x 0.5 to 4 mm² and stranded from 2x 1 to 10 mm². AWG equivalents are 2x 16 to 12 solid and 2x 14 to 10 stranded, with a single 8 AWG maximum. The front of the contactor is IP20 (finger-safe), but the terminals themselves are IP00 — so live parts are exposed once the wiring compartment is open. The coil holds at 0.8 to 1.1 times the rated voltage at 50 Hz; below 0.8 x Us it drops out, which is standard for this class.
