Hubbell HBL420IS Quad Surge Receptacle 20A 125V Ivory

Indoor Commercial Surge Receptacle

The Hubbell HBL420IS is a surface-mount quad receptacle rated for 20A at 125V AC. It provides four NEMA 5-20R straight-blade outlets with MOV-based surge suppression for indoor dry locations. The polycarbonate housing carries a UL94 V-2 flammability rating and brass contacts. UL Listed to UL498 and CSA Certified to C22.2 No.42, it suits commercial environments needing multiple protected outlets.

Build Integration Requirements

The device mounts on a surface and accepts #12 AWG copper conductors via terminal screws. Its two-pole, three-wire grounding configuration fits standard commercial wiring practices. The quad layout consolidates four protected outlets into a single gang space, freeing wall area otherwise occupied by separate surge strips. LED status indicators allow visual confirmation of protection status without additional test equipment.

Sustained Load Behaviour

Each protection mode is rated at 80 joules and 6500A, delivering up to 240 joules per mode across the circuit. The MOV components clamp transient voltages continuously during extended operation rather than only during brief spikes. The receptacle maintains its 20A, 125V rating under continuous load while the surge network remains active, and the LED indicators signal if the suppression capability degrades over time.
