Light Archon Vanguard 100A 2-Pole Circuit Breaker
Reviewed pricing, lead time, freight, and final configuration are confirmed during quote review before order release.
The Light Archon Vanguard 100A 2-pole breaker anchors heavy feeder and main-class duty in the industry-standard 1 in. plug-on format. It backfeeds or protects 100 A of 120/240V service in two pole spaces, serving subpanel feeders and main positions in load centers listed for it. Quote-first: add it to your quote list and the trade desk confirms panel fit before release.
The thermal magnetic trip unit carries a common trip across both poles and a 10 kA interrupt rating. The plug-on connection lands the breaker on the bus without mounting hardware, and the two-space footprint keeps subpanel feeder layouts compact. Typical work: feeding a detached garage or shop subpanel, protecting a 100 A service section, or replacing a feeder position during a panel refresh, always with the load center listing and conductor sizing checked by your electrician.
