Overview
The Hubbell HBL7485 is a heavy-duty industrial midget twist-lock plug rated for 15A at 125/250V AC. Designed for use with portable equipment and industrial cord sets, this 3-pole 3-wire non-grounding connector features screw terminals and a male plug configuration that mates with NEMA ML-3R receptacles.
