Series 16 male connector for temporary power

The Hubbell HBL400MBN is a single-pole male connector built for temporary electrical power distribution. It accepts cable sizes from 2/0 to 4/0 AWG and uses a taper-nose design with double set-screw terminals for secure wire retention. The thermoplastic elastomer housing carries an Insulgrip-style profile for easier handling in field conditions. This connector is suited for industrial and event-power applications requiring quick, reliable hook-ups.

NEMA 3R, 4X, 12 enclosure with UL1691 listing

The housing meets NEMA Type 3R, 4X and 12 requirements, providing protection against rain, hose-directed water, dust and non-corrosive coolants. It carries a UL94 HB flammability rating and is listed under UL1691 for single-pole locking-type separable connectors. Brass cam contacts handle up to 400 A at 600 V AC or 250 V DC without overheating in normal service. No fan or active cooling is involved, so operation is silent.

400 A, 600 V AC rating on 2/0–4/0 cable

The decisive specification is the 400-ampere, 600-volt AC rating on cables from 2/0 to 4/0 AWG; if your load or cable size falls outside this range the connector is not suitable. It mates with Series 15, Series 16 and Insulgrip devices, so compatibility with existing cam-lock inventories must be verified before purchase. The double set-screw terminal requires proper torque tools for installation. Buyers needing higher ampacity or different voltage classes must select another device.

Questions about this item

How do I install the double set screw terminal on this Series 16 male connector, and what step is often missed?

Strip the 2/0 to 4/0 cable to the correct length, insert fully into the brass single cam contact, then tighten both set screws evenly to secure the connection.

What maintenance or replacement will this connector need after extended use in temporary power distribution?

Inspect the thermoplastic elastomer housing and Insulgrip® style contacts for wear, cracking, or corrosion; replace the unit if the double set screws no longer hold cable firmly.

What limit appears first when this 400 A connector runs continuously at full load?

The 600 V AC or 250 V DC voltage rating and UL94 HB flammability threshold define the sustained-use envelope; do not exceed the 400 A amperage rating.
