Single Pole Connector for Temporary Power

The Hubbell HBLNCGN single pole connector is built for temporary electrical power distribution. Rated at 400 A AC and 600 V AC or 250 V DC, it suits high current applications. The non-metallic nylon cover meets NEMA 12, 3R and 4X enclosure ratings. cUL and UL listing confirms compliance with recognised safety standards.

Nylon Cover and Series 16 Compatibility

The green nylon housing provides weather resistance for outdoor or damp environments. A protective cover shields the contact when the connector is not engaged. It fits Series 16 devices and is UL 1691 compatible for standardised pin connections. The single pin terminal accepts large conductors used in temporary distribution systems.

Limits of the Single Pin Interface

The single pin design carries one phase or conductor per connector, so multi-phase circuits require multiple units. Current capacity is fixed at the 400 A rating and cannot be exceeded by the connector itself. Voltage is limited to the stated 600 V AC and 250 V DC maximums. The non-metallic cover is not rated for continuous submersion or hazardous locations beyond the listed NEMA classes.

Questions about this item

What current does the 600 V AC rating cap in practice?

The connector is rated for 400 A AC at 600 V AC, so the voltage rating caps the usable current at 400 amps.

What physical space does the Series 16 non-metallic cover need to mount?

It fits Series 16 panel cut-outs and uses the standard Series 16 mounting pattern with the nylon cover adding minimal depth.

How is the single pin terminal installed, and what step is often missed?

Insert the pin fully into the terminal sleeve, tighten the set screw to the specified torque, then snap the protective cover closed to meet NEMA 4X sealing.
