Cutler Hammer QCGF2040 is a molded case circuit breaker designed for providing reliable overcurrent protection in industrial and commercial electrical systems. It features a 40A current rating and a 240V AC voltage rating, housed within a compact, durable two-pole feed-thru configuration. The breaker utilizes a thermal-magnetic trip mechanism for both long-time and instantaneous (LI) protection functions, ensuring coordination for overloads and short circuits, and it is constructed to accept wire sizes from AWG 14 to AWG 4 for both aluminum and copper conductors. Compliant with industry standards, it offers an interrupting capacity of 10kA at 120V and is typically applied in panelboards, switchboards, and motor control centers for single-phase power distribution.
