NC0220 - 20Amp Circuit Breaker

NC0220 - 20Amp Circuit Breaker

The NC0220 20 Amp double pole circuit breaker is designed to protect 120/240V electrical circuits from overloads and short circuits in residential and light commercial panels. Rated at 20 amps with a 10kA interrupting capacity, this breaker helps prevent damage to wiring and connected equipment by interrupting fault currents quickly and safely. The built-in thermal magnetic trip mechanism responds to heat buildup from overloads and reacts instantly to high fault currents. Its compact body fits neatly into compatible panelboards, and the stab-on connection provides a secure, stable fit during installation or replacement.

Key Features and Benefits

• 20 Amp Rating: Provides reliable protection for standard 20A branch circuits.
• Double Pole Configuration: Designed for 120/240V applications requiring two connected poles.
