Main circuit terminals accept 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or up to 2x (0.75–4 mm²) solid/stranded. AWG equivalents: 2x (20–16), 2x (18–14), 1x 12. Terminals are IP20 finger-safe.
Duty ratings and coordination
AC-12 rating at 10 A covers resistive loads like heaters. AC-2 at 400 V delivers 4 kW for slip-ring motors; AC-4 at 400 V handles 8.5 A for reversing or inching duty. For type 2 coordination, use a gL/gG fuse rated 20 A; type 1 coordination allows up to 35 A. Coil operates at 50/60 Hz with a voltage tolerance of 0.8–1.1 at 50 Hz and 0.85–1.1 at 60 Hz. Rated control supply voltage is 110 V at both frequencies.
Environmental limits
Storage temperature range exceeds the operating window — that limit governs handling, not running.
