Eaton CH220AF Two Pole Molded Case Circuit Breaker

The Eaton CH220AF is a two-pole molded-case circuit breaker (MCCB) rated for 20 amps at 240 volts. The 2-pole design interrupts both conductors of a 240 V circuit, delivering overcurrent protection by opening the circuit when the load current exceeds its 20 A rating. This part number, CH220AF, specifies the device’s electrical configuration and rating, making it suitable for protecting wiring and connected equipment on a 240 V supply. Molded-case breakers like the CH220AF integrate the conductors, insulation, and trip mechanism into a single compact module, providing a reliable means of interrupting fault currents and reducing the risk of damage from overloads. The 240 V, 20 A specification identifies the operating envelope for normal use and compatibility with typical 240 V distribution systems. As a two-pole device, it ensures simultaneous disconnection of both live conductors in a 240 V circuit, which is important for safety in dual-hot configurations and for maintaining proper fault clearing on multiwire circuits. This amperage and voltage combination is typical for protecting two-pole 240 V circuits.
