Hospital-Grade Locking Connector

The Hubbellock HBL23001HGB is a 20 A, 125 V AC locking connector built for hospital-grade applications. Its nylon housing and insulated body suit indoor dry locations where a secure, grounded connection is required. The straight-orientation, non-NEMA design accepts two-pole, three-wire grounding configurations for reliable power delivery in medical environments.

Bronze Contacts and Cord Grips

Bronze contacts are moulded into the nose to resist damage during repeated insertion and removal. Mechanical cord grips provide strain relief for cables ranging from .320 in to .660 in diameter. Pressure terminal screws accept #14 AWG to #12 AWG conductors, giving installers a straightforward screw-terminal wiring method without specialised tooling.

Rated for 20 A Continuous Duty

The connector operates continuously from -40 °C up to +75 °C, covering demanding indoor conditions. It carries UL listing and UL94 HB flammability rating with IP20 ingress protection. It does not serve applications requiring higher amperage, NEMA-standard pinouts, outdoor wet-location ratings or connector styles beyond the straight, locking interface described.

Questions about this item

When will the bronze contacts or nylon housing need replacement under normal hospital use?

Bronze contacts are molded into the nose for damage resistance; the nylon housing is rated for continuous operation up to 75 °C. Inspect periodically for discoloration, cracking or loose terminal screws and replace if any damage appears.

What limit appears first during sustained 20 A loading — conductor heating, terminal torque or housing temperature?

The connector is rated for continuous 20 A at 125 V AC with a maximum operating temperature of 75 °C; the housing temperature limit is reached before conductor or terminal limits under full load.

How warm does the nylon housing get and does it make any noise when powering equipment all day?

The housing operates silently; at full 20 A load it can reach the rated 75 °C maximum, so ensure adequate ventilation in the enclosure.
