The Eaton NSB CHFCAF120 Miniature Circuit Breaker is a 1-pole, 20-amp, 240-volt protective device designed to interrupt current during overcurrent events. It provides branch-circuit protection by quickly opening the circuit when an overload is detected, helping prevent damage to conductors and equipment. The CHFCAF120 designation identifies this specific variant within Eaton’s NSB series for installation in compatible electrical distribution systems.
