It is a 4-pole (4P) device rated for AC-7A and AC-7B utilisation categories, meaning it handles both resistive and lightly inductive loads — typical for contactor-duty applications like fan coils, pumps under 1 kW, and resistive heating banks. The control circuit is 110 V AC at 60 Hz, with a drop-out range of 0.2...0.75 Uc and an operating range of 0.85...1.1 Uc at 50 Hz.
The continuous thermal current (Ith) is 16 A at 50 Hz for the power circuit, with an average impedance of 2.5 mOhm, so the contactor is sized for a 16 A feeder. The associated fuse rating is 16 A gL at ≤ 440 V for the power circuit, which coordinates with the contactor's short-circuit withstand. Mechanical durability is 1,000,000 cycles; electrical durability is 100,000 cycles for both AC-7A and AC-7B duty — this is the wear life under rated load, not the mechanical cycle count.
Clip-on mounting on standard DIN rail (35 mm per EN 60715). The contactor occupies 2 modules of 18 mm width each (36 mm total), so it fits a standard 18 mm pitch DIN-rail terminal block layout. Height is 85 mm, depth 62.5 mm — shallow enough for most 100 mm deep enclosures. Screw-clamp terminals on both control and power circuits: control accepts up to 2 x 2.5 mm² flexible without cable end; power accepts up to 2 x 6 mm² flexible without cable end. Tightening torque is 0.8 N.m for both circuits. IP20 protection (in enclosure per VDE 0106) means it is not sealed against dust ingress — install in a panel with at least IP40 enclosure.
