Heavy Duty IEC 60309 Industrial Power Extension Cord (3 / 4 / 5 Pin)
Heavy Duty IEC 60309 Industrial Power Extension Cord | 3/4/5 Pin, IP44/IP67 CE Certified
Our IEC 60309 heavy-duty industrial extension cord follows international IEC 60309 standard for industrial pin-and-sleeve connectors. We offer 3-pin, 4-pin and 5-pin versions to match single-phase and three-phase power requirements.
- 3 Pin (2P+E): Single phase 230V, for common industrial single-phase equipment
- 4 Pin (3P+E): 3-phase 400V, 3 live wires + earth
- 5 Pin (3P+N+E): 3-phase 400V, 3 live wires + neutral + earth
Available in 16A and 32A ratings, the industrial connectors feature a secure locking system. Once plugged in, the lock mechanism stops accidental pull-out, guaranteeing stable power supply even under vibration and rough handling. IP44 splash-proof or IP67 fully waterproof options are selectable for different working environments.
The cable adopts H07RN-F heavy rubber jacket, abrasion-resistant, oil-resistant, UV-resistant and flexible at low temperatures. 100% pure copper conductors deliver low resistance and stable power transmission under full load. High impact resistant nylon connector housing resists shock, dust and corrosion. All units carry CE certification and pass strict factory electrical testing before shipment.
