Industrial Locking Connector 20A 125V 250V 480V

The Hubbellock HBL23002GB is a non-NEMA locking connector rated for 20 A at 125 V AC, 250 V DC and 480 V AC. It uses a two-pole three-wire layout with bronze contacts moulded into an impact-resistant nylon body. The device accepts 16 AWG to 12 AWG stranded copper wire and cable diameters from .320" to .660". It is built for industrial power-distribution tasks where secure locking connections are required.

Wiring and Installation Checks

Verify that your supply voltage matches one of the rated levels and that the circuit is protected for 20 A. Confirm the conductors are stranded copper within the 16 AWG to 12 AWG range and that the outer cable diameter falls between .320" and .660". The screw terminals follow UL 498 identification; ensure your wiring scheme aligns with those markings. The three-piece strain-relief clamp must be assembled correctly to maintain the IP30 rating.

Thermal and Environmental Limits

The connector is rated for continuous operation from -40 °C to +75 °C without derating. Its thermoset interior and nylon housing carry a UL HB flammability classification. Bronze contacts resist damage during repeated mating cycles. The IP30 rating provides limited protection against dust ingress but is not a water-tight seal. No active cooling or forced airflow is required in normal use.
