No auxiliary contact blocks are included — the kit carries zero instantaneous auxiliary contacts and zero NC main contacts, so if your circuit needs a mirror contact or a feedback signal, that block is ordered separately.
The AC-3 motor rating is 5.5 kW at 690 V and 4.5 kW at 500 V — that's the figure that governs motor switching on a 690 V line. At 400 V AC-3 the rating is implied by the 4.5 kW at 500 V and 5.5 kW at 690 V; the AC-4 rating at 400 V is explicitly 8.5 A, which covers reversing or inching duty where the contactor makes and breaks stalled-rotor current. For resistive loads (AC-1), the contactor is rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. The AC-12 maximum operating current is 10 A, which applies to control-circuit loads like PLC outputs or relay coils. Type 2 coordination requires 25 A. The contactor is rated for 50 Hz; the operating factor at 50 Hz is 0.8 to 1.1. Mechanical endurance is 10 million cycles typical.
Terminal wiring — what fits
Main-circuit screw terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded conductors: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents: 2x (16 to 12), 2x (14 to 10), 1x 8. Strip length and torque values are per the terminal marking on the contactor.
