Hubbell HBL1223RKL 3-Way Locking Dimmer Switch

This 20 A, 120/277 V AC switch provides maintained three-way control for lighting or fan circuits in commercial and industrial settings. The stainless steel barrel key locking mechanism prevents unauthorised operation while the impact-resistant body withstands harsh environments. Screw terminals accept 14 to 10 AWG conductors for secure back or side wiring.

Sustained-load behaviour of the 20 A switching

The switch is rated for continuous 20 A resistive, inductive and 1 1/2 hp motor loads at the listed voltages. UL listing confirms the device meets temperature-rise and endurance requirements for prolonged operation without nuisance tripping or contact degradation. The locking actuator maintains its position under vibration so the circuit state remains stable over long duty cycles.

Installation checks before ordering

Verify the existing wall box accommodates a single-gang locking switch with screw-terminal wiring. Confirm the supply voltage is 120 V or 277 V AC and that the connected load does not exceed 20 A or 1 1/2 hp. Ensure conductors are solid or stranded copper within the 14 to 10 AWG range for proper terminal engagement.

Questions about this item

Does the 20 A barrel-key switch generate audible noise or heat when the lighting circuit runs continuously?

The HBL1223RKL is a mechanical locking switch with no moving parts that produce sound or measurable heat during normal operation at its 20 A rating.

What wiring components must already be present for the 1223 switch to install and function?

A compatible back or side-wired box, 14 to 10 AWG conductors, a 120/277 V AC supply, and a matching 3-way companion switch are required for installation.

Will the 1223 locking dimmer work alongside existing 120/277 V toggles on the same multi-way circuit?

Yes, the 3-way switch is UL Listed for 120/277 V AC circuits and operates with standard companion switches on the same voltage.
