Eaton CHN220GF Miniature Circuit Breaker

The Eaton CHN220GF is a two-pole miniature circuit breaker from the NSB CHN family, rated 20 A at 240 V AC for 1‑phase circuits. With a 2P configuration, it protects both conductors of a 240 V single‑phase line and interrupts current during overload or short circuits, helping prevent wiring damage and equipment failure. It operates at 50/60 Hz, suitable for standard power systems that supply 240 V single‑phase loads. As part of Eaton's CHN NSB line, the CHN220GF provides overcurrent protection for branch circuits in 240 V single‑phase installations up to 20 A. The CHN220GF designation identifies its exact rating within the CHN series, facilitating correct identification and replacement in existing installations.
