Hubbell HBL26420 Industrial locking receptacle with Hubbellock configuration

Industrial locking receptacle for high-current power connections

The Hubbell HBL26420 is an industrial-grade Hubbellock® locking receptacle engineered for high-current power distribution in demanding electrical environments. Designed for 60 amp, 600 volt AC applications, this receptacle supports multi-phase systems requiring secure mechanical engagement and reliable electrical continuity.

Hubbellock industrial receptacle construction and configuration

This model features a non-NEMA, 3-pole 4-wire grounding configuration suitable for specialized industrial power systems. The long housing is manufactured from cast aluminum, providing mechanical durability and resistance to impact in industrial settings. A metallic lift cover protects the receptacle interface when not in use, while the phenolic interior supports electrical insulation and structural stability.

Screw terminals are provided for conductor termination, accommodating solid or stranded copper conductors within the specified wire range. Terminal identification is marked in accordance with UL 498 requirements to support correct field wiring and inspection practices.

Secure power connection through the Hubbellock locking interface

The Hubbellock locking design enables positive engagement between plug and receptacle, reducing the risk of accidental disconnection under load or vibration. This interface supports controlled connection and disconnection in industrial workflows and is certified for current interrupting at full rated current.

Electrical, environmental, and compliance characteristics

The HBL26420 is rated for 60A at 600V AC and withstands a minimum dielectric voltage of 2,000V. Environmental suitability includes IP44 moisture resistance when properly installed and a flammability rating of UL 94 V0. The device is listed to UL standards and certified to CSA standards, supporting use in regulated industrial electrical installations.
