Eaton CHCAF120PN Miniature Circuit Breaker Type CHCAF120PN

Eaton NSB CHCAF120PN Miniature Circuit Breaker is a CH-series, single-pole MCB designed to protect a single circuit in 240-volt electrical installations, delivering rapid interruption of fault current while occupying a compact form factor that helps maximize panel density. The CHCAF120PN is rated for 20 A and operates at 50/60 Hz, indicating its suitability for installation in regions with either 50 Hz or 60 Hz mains, and the CH designation identifies this unit as part of Eaton's standardized CH family of protective devices. This part is uniquely identified by the model number CHCAF120PN within the NSB product lineup, supporting precise ordering, replacement, and documentation in maintenance records and electrical schematics. As a protective device, it is intended to interrupt current under overcurrent conditions to help prevent overheating, insulation damage, and potential equipment failure in 1-pole circuits. The CHCAF120PN's 1P, 20 A, 240 V, 50/60 Hz specification set defines its core operating envelope for branch circuits in electrical distribution that require compact, reliable MCB protection.
