Hubbell HBLDMY Double Connector

The Hubbell HBLDMY is a straight-blade double connector built for industrial power distribution. Its male-to-male configuration suits temporary feeds, generator tie-ins and heavy-duty equipment links where a secure 400 A connection is required.

Thermals and enclosure rating

The housing is moulded from thermoplastic elastomer rated for continuous operation from -40 °C to 75 °C. NEMA 12, 3R and 4X ratings confirm protection against dust, rain, sleet and hose-directed water without forced cooling.

Series 16 compatibility
