Eaton Cutler-Hammer QC2040N 2 Pole Circuit Breaker

The Eaton Cutler-Hammer QC2040N 2 Pole Circuit Breaker is a 40-amp, 240-volt protective device designed to guard two-pole circuits in electrical panels by interrupting fault currents and preventing overheating of conductors. Identified by the QC2040N model designation, this breaker belongs to the Cutler-Hammer QC series and provides reliable overcurrent protection for 240V branch circuits in compatible Eaton panel boards. Its 2-pole design protects both hot legs of a 240V circuit, enabling a single device to safeguard the entire circuit path and simplifying wiring within panels that support QC-type breakers. Use this breaker in panels that accept QC-series devices to ensure proper fit and performance for 40A, 240V circuits, and verify that the enclosure and conductor sizes meet local electrical codes. Key specs: model QC2040N; configuration 2-pole; rating 40 A; voltage 240 V.
