Rated for 7.5 kW at both 500 V and 690 V, this contactor handles the common European 400 V three-phase motor curve with headroom. The AC-2 rating at 400 V is 5.5 kW, and the AC-4 rating at 400 V is 12.5 A — the latter matters for reversing or inching duty where the contactor makes and breaks full load current.
Width is 45 mm, height 85 mm, depth 90 mm — the S0 footprint. Main current circuit uses screw-type terminals accepting 2x (0.25 to 2.5 mm²) solid, 2x (1 to 2.5 mm²) stranded, or up to 2x 10 mm². AWG equivalents are 2x (16 to 12) solid, 2x (14 to 10) stranded, or 1x 8. Strip and torque per Siemens standard — no special tooling required.
Short-circuit coordination and protection
For type 1 coordination (contactor may need replacement but the circuit is cleared), the fuse rating is gL/gG 63 A. These values govern the short-circuit protection selection for the motor branch circuit.
