Top Pick Eaton / Cutler-Hammer CHF240 – 40A 2 Pole Miniature Circuit Breaker

Built to handle heavier residential loads, this 40-amp device safeguards critical circuits against overloads and short circuits. The signature trip flag mechanism provides clear visual feedback, allowing electricians to quickly spot tripped lines. It snaps into any standard Eaton or Cutler-Hammer Type CH panelboard. This model serves as a modern replacement for the older CH240. With a 10kAIC rating and HACR certification, it effectively supports dedicated heating and air conditioning systems.
