For AC-4 reversing or inching duty at 400 V, the rated operational current is 8.5 A — a lower figure that reflects the increased switching stress of plugging and jogging. The coil operates on 50/60 Hz with an operating range of 0.85 to 1.1 times rated voltage at 50 Hz and 0.8 to 1.1 at 60 Hz, so it holds in during brownout conditions down to roughly 85% of nominal.
Termination and wiring constraints
Both main and auxiliary circuits use screw-type terminals. The main contacts accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) — so you can double up smaller conductors for daisy-chaining, but a single 4 mm² is the max per clamp. AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12. The auxiliary contacts share the same wire range.
Short-circuit coordination and protection
These values matter when designing a panel for selectivity — the upstream fuse must clear a fault before the contactor welds.
The product carries a substance prohibition date of 01.07.2006, which aligns with the original RoHS directive. For current RoHS/REACH declarations, the manufacturer provides compliance documentation with each shipment.
