Why this breaker matters

When protecting critical branch circuits, you need a breaker that responds accurately to overloads and short circuits while staying securely connected in the panel. The QOB360’s bolt-on construction minimizes movement that can loosen connections over time, and the thermal-magnetic trip mechanism provides predictable behavior during fault events. This means you get faster fault clearance, reduced arcing risks, and longer equipment life for your panelboard or load center.
