Hubbell HBLNCBK 400 A Single Pole Connector

The Hubbell HBLNCBK is a single pole connector rated for 400 A at 600 V AC or 250 V DC. It uses a nylon body with a black non-metallic cover and a single pin terminal that assembles without special tools. The device meets cUL and UL requirements and suits NEMA Type 12, 3R and 4X enclosures.

Suited for temporary power distribution

Electricians running temporary feeds who need a weather resistant, tool free connection compatible with UL1691 standard connectors will find this connector fits the application. Installers who require multi pin configurations, higher voltage ratings or metallic housing should look at other products.

Deciding specification is the 400 A single pin

The connector delivers a 400 A single pin connection at 600 V AC with a nylon non metallic cover that meets NEMA Type 12, 3R and 4X requirements. This rating determines whether the device matches the load and enclosure class of the temporary power system.

Questions about this item

How do I install the Hubbell HBLNCBK connector and what step do people often miss?

No special tools are required for assembly or disassembly; the step often missed is confirming the single pin terminal is fully seated before closing the non-metallic cover.

What maintenance or replacement will the Hubbell HBLNCBK connector need over time?

Inspect the nylon housing and non-metallic cover for cracks or UV degradation; replace the connector if the weather-resistant rating is compromised or the single pin shows pitting.

What is the first limit reached on the Hubbell HBLNCBK connector under sustained 400 A load?

The 600 V AC / 250 V DC voltage rating and the 400 A ampere rating define the electrical limits; sustained operation must stay within both values to meet UL1691 and cUL requirements.
