Main Circuit Breakers

The main breaker controls and protects all the power coming into your load center. A replacement must be a model listed on your panel's label: main breakers are specific to the panel brand, type and amp rating.

  • Square D QO panels: QOM100VH, QOM125VH, QOM2100VH, QOM2150VH, QOM2200VH bolt-on mains
  • Eaton CH panels: CSR2100N, CSR2125N, CSR2150N, CSR2175N, CSR2200N
  • Siemens: EQ9685 200 amp main breaker kit
  • Square D PowerPacT: QDL22200
  • Eaton: CCV2200 and BW2200 200 amp bolt-on mains

To find the right part, you'll need the panel model from the label inside the door and the amp rating printed on the existing main breaker. Send us a photo and we'll confirm the match.

Safety: the lugs feeding a main breaker stay energized even with the breaker off. Main breaker replacement should be done by a licensed electrician, with the utility disconnecting power first.
