The coil pulls 3.5 VA at both 50 and 60 Hz, so the control transformer sizing is the same regardless of your line frequency. The coil itself is spring-type terminals, which means no screw clamping — strip the wire, push it in, done. That saves time on the panel build, but if your shop standard is screw terminals, the wireman will notice the difference. Keep 10 mm clearance upwards, downwards, and sideways, and 20 mm forwards for the arcing zone (arcing time 10-20 ms).
Wiring and auxiliary contacts
Main contact wiring accepts solid conductors 2.5 to 16 mm² and stranded 6 to 70 mm². The auxiliary switch is included — you get 10 normally open and 2 normally closed main contacts, plus the auxiliary block is built in. For the coil control wiring, it takes 2x (0.5 to 2.5 mm²) solid or stranded.
