Hubbell HBLDMO 400 A double connector

This Hubbell HBLDMO double connector provides a male-to-male link rated for 400 amps at 600 volts AC or DC. The thermoplastic elastomer housing is coloured orange and carries NEMA 12, 3R and 4X enclosure ratings for harsh environments. It is designed for single-pole power distribution where a reliable high-current joint is required.

Sustained-load performance

Brass contacts maintain conductivity at the full 400 A rating across an operating range of -40 °C to 75 °C. The NEMA 4X rating ensures the connection resists water ingress and corrosion during continuous outdoor or wash-down duty. Thermal stability is preserved without derating within the stated temperature limits.

Upgrade path and fit

The connector mates with Series 16 components, replacing lower-rated or non-NEMA-rated links in existing installations. The jump is justified when a circuit demands 400 A capacity combined with NEMA 12, 3R and 4X environmental protection. It does not suit applications requiring female contacts or a different series interface.

Questions about this item

How much heat can the HBLDMO double connector handle when it runs continuously at its 400 A rating?

The connector is rated for a maximum operating temperature of 75 °C and a minimum of -40 °C, so it will stay within its thermal limits during continuous 400 A use.

What cable or series must I already have for this male-to-male connector to work?

It is designed to mate with Series 16 devices, so you need a Series 16 cable or receptacle to complete the connection.

Will the orange thermoplastic housing survive outdoors next to older NEMA-rated gear?

Yes, the housing carries NEMA 12, 3R and 4X enclosure ratings, making it suitable for wet, dusty or corrosive environments alongside legacy equipment.
