Eaton Cutler-Hammer BAB3020C Circuit Breaker

The Eaton Cutler-Hammer BAB3020C is a 2-pole circuit breaker rated for 20 amps at 240 volts, designed to interrupt fault currents with a 10K interrupting capacity, providing a robust level of protection for 240V branch circuits. As a member of the BAB-series, it operates by simultaneously disconnecting both hot legs in 240V circuits when overcurrent or fault conditions are detected, helping prevent overheating, arcing, and damage to wiring and downstream equipment. The model designation BAB3020C encodes its key ratings—20A, 240V, 2P—while the 10K rating indicates the maximum fault current the breaker can interrupt without failing, a critical spec for planning protective devices within a distribution panel. This specification set makes the BAB3020C suitable for residential or light commercial installations where a two-pole, 20-amp protection device is required for 240V circuits, ensuring dependable overcurrent protection within distribution panels.
