Light Archon Aegis 20A Single-Pole Circuit Breaker
Reviewed pricing, lead time, freight, and final configuration are confirmed during quote review before order release.
Light Archon Aegis breakers put the everyday 20 A single-pole slot on one platform in the industry-standard 1 in. plug-on format. Protection levels run from the standard thermal magnetic unit to a tandem two-circuit unit, an AFCI unit, and a dual function AF/GF unit, so one line item covers the full branch circuit schedule. Every unit is quote-first: add it to your quote list and the trade desk confirms panel fit before release.
The standard unit trips to the center position on overload or fault current, so a tripped handle reads at a glance. The tandem unit fits two 20 A circuits in one pole space where the panel label permits it. AFCI and dual function units add arc fault and combined arc plus ground fault protection for the dwelling circuits the NEC calls out. Interrupt rating is 10 kA across the line, and terminations accept #14-4 AWG Cu/Al conductors at 60 C or 75 C.

Frequently Asked Questions
What panels does this fit?
It fits Light Archon LC series and industry-standard 1 in. bolt/plug-on load centers - verify panel compatibility at quote review.
Which protection level do I need?
Standard units cover most branch circuits. The NEC calls for AFCI protection in most dwelling living areas and combined AF/GF units where the plan calls for both arc and ground fault protection on one circuit. Your electrician and the trade desk confirm the schedule at quote review.
Can I use the tandem unit anywhere in the panel?
No. Tandem units belong only in slots the panel label lists as tandem-permitted. The panel schedule is checked at quote review.
How is this sold?
