Hubbell HBL400FY Single Pole Connector

This Hubbell HBL400FY connector is a female single pole device rated for 400 amps and built for temporary power distribution. It suits entertainment, theme park, carnival and film production crews who need reliable, tool-free connections in demanding environments. The yellow housing and Series 15 or 16 compatibility make it easy to identify and integrate into existing temporary power systems.

Sustained Load Behaviour

The connector uses an extra-long non-conductive inner sleeve and a high-strength retaining screw to lock contacts securely inside the insulated sleeve. This design resists loosening under vibration and continuous current flow typical of multi-day events or permanent temporary installations. No special tools are required for assembly or disassembly, so maintenance crews can inspect and reseat contacts quickly between shows without downtime.

400 Amp 3R 4X Rating Decides Fit

The single specification that determines suitability is the 400 amp, NEMA 3R and 4X rated female configuration with cable range 2/0 to 4/0. Buyers who need a lower amperage rating, a male counterpart, or a different environmental rating cannot use this part. Verify the ampacity and ingress protection match your distribution plan before ordering.

Questions about this item

Does the HBL400FY connector generate noticeable heat or noise when supplying power continuously?

The connector is a passive single-pole device with no moving parts or electronics, so it produces no noise and negligible heat during continuous operation.

What cable size must I already have for the HBL400FY to terminate correctly?

The connector accepts 2/0 to 4/0 cable, and the insulated sleeve includes cut-off points for a secure fit on those conductors.

Will the HBL400FY mate with older Series 15 plugs already in my inventory?

Yes, the turn-and-lock symbol and Series 15/16 design allow it to mate with existing Series 15 single-pole plugs without special tools.
