Screw-type terminals on the main circuit accept stranded conductors up to 2x 25 mm², and the auxiliary circuit accepts solid wire from 0.5 mm² up to 4 mm². That covers most control wiring in a 400 V panel — no need for ferrule adapters on the main power legs. The contactor is rated for side-by-side mounting with no derating, which saves rail space when grouping multiple contactors in a motor control centre.
The contactor is rated for 50/60 Hz operation with a voltage tolerance of 0.8...1.1 x rated at 50 Hz and 0.85...1.1 at 60 Hz. Arcing time sits at 10...15 ms, with an AC pickup/dropout time of 7...20 ms. Maximum switching rates vary by duty: 1200 cycles/hour at AC-1 (resistive), 1000 at AC-3, 750 at AC-2, and 250 at AC-4 (plugging/inching). The auxiliary contact block — rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V — covers control-circuit signalling and interlocking without an add-on module for most applications.
