Hubbell HBLDMBK Double Connector

The Hubbell HBLDMBK is a gender-reversing single-pole connector rated for 600V AC and 600V DC with a 400 A current rating. Its thermoplastic elastomer housing carries NEMA 12, 3R and 4X enclosure ratings and operates from -40 °C to 75 °C. The black unit measures 4.65 in high by 1.54 in wide and weighs 0.71 lb. It is compatible with Series 16 devices.

Suited for high-current power distribution

Electrical contractors and maintenance teams running temporary or permanent high-amperage feeds will find the 400 A rating and reversing male-male configuration useful. Installations that require a lower current rating, a different voltage class or a female contact arrangement should look at other connector styles.

Verify series compatibility and environmental fit

Confirm that the mating devices are Series 16 types before ordering. Check that the NEMA 12, 3R and 4X ratings satisfy the enclosure requirements of the installation site. Ensure the operating temperature range of -40 °C to 75 °C covers the expected ambient conditions.

Questions about this item

What Series 16 cable assemblies must I already have to connect with this male-male double connector?

You need Series 16 single-pole cable assemblies with matching 400 A, 600 V ratings to plug into each end of the gender-reversing connector.

Will the NEMA 12, 3R and 4X ratings on this connector match the enclosures on my existing Series 16 plugs?

Yes, the connector carries the same NEMA 12, 3R and 4X ratings, so it maintains the ingress protection of your current Series 16 devices.

How can I confirm the brass contacts are seated correctly after mating the two Series 16 cables?

Push each cable until the locking latch clicks, then verify the connection by measuring continuity across the 400 A circuit with a multimeter.
