Technical Parameters Parameter / Feature Specification / Detail Series / Model AF110‑30‑11 (3‑pole contactor) Poles (Main Contacts) 3 main poles, normally‑open (3 NO) Auxiliary Contacts 1 NO + 1 NC (or per variant) auxiliary contact block Main Circuit Rated Voltage Up to 690 V AC (some versions up to 1000 V AC, depending on coordination) Control (Coil) Voltage Range Wide-range: e.g. 100–250 V AC or DC (many variants) — suitable for 50/60 Hz supply or DC control circuits Utilization / Application Motor control, general-purpose power switching, 3‑phase load switching, industrial machinery, HVAC, pumps, compressors, etc. Rated Operational Current / Load Capacity Rated for heavy loads (frame AF110) — suitable for high current and high-power circuits (see application rating table per motor / load type) Insulation / Surge & Impulse Ratings Insulation voltage ~1000 V; impulse withstand voltage U_imp ~8 kV (suitable for industrial environment) Operating Temperature & Environment Ambient range (depending on coil and mounting) typically from –40 °C to +70 °C (without overload relay), broader storage range; designed for industrial environments. Standards & Compliance Compliant with IEC 60947‑1 / IEC 60947‑4‑1 (for AC contactors), and typical national/international standards for motor and power contactors. Mounting / Installation Standard DIN‑rail or panel / busbar mounting; screw‑type main and auxiliary terminals; supports solid, stranded, or lug-type cables per connection guidelines. Typical Uses Three-phase motor start/stop control; power-circuit switching; industrial machine control; HVAC, pumps/compressors; general power distribution switching where robust contactor is needed.
