It is the connector used to build the mains feed cable into lighting fixtures, amplifiers, LED screens and powered loudspeakers that have a blue power-in chassis socket; the grey HP-3-FG is the matching power-out version for linking onward. It is rated 25 A at 250 V AC, with brass/silver screw contacts, a PA66 GF30 glass-filled thermoplastic housing, IP54 protection, UL94 V-0 flammability, UL recognition E339831, a typical cable retention force of 200 N and a cable outer diameter range of 5 to 15 mm. Operating temperature is -25 to +75 °C. It is not a true-mains (TRUE1) connector, so it should not be connected or disconnected under load.
