The Powervamp EC1 plug (400V, 32A) is an industrial IEC 60309-2 type aircraft ground power connector used to supply three-phase AC electrical power to compatible Powervamp equipment such as ground power units, chargers, and support systems.

It is rated for 400V AC, 32 amps, 3-phase + neutral + earth (5-pole configuration) and uses the standard 6H keying position, ensuring correct phase alignment and preventing mismating with incompatible systems. The red color coding indicates high-voltage (380–480V class) industrial power systems.

This plug is typically used on EC1 series ground support equipment connections, providing a robust and weather-resistant interface for temporary or permanent power distribution in aviation hangars, maintenance facilities, and ramp operations.

The connector features a rugged impact-resistant housing, internal strain relief, and screw-clamp terminals for secure wiring, making it suitable for repeated industrial use in demanding environments.
