NE221020 - 20Amp Circuit Breaker

NE221020 - 20Amp Circuit Breaker

The NE221020 20 Amp circuit breaker is a two-pole, bolt-on molded case breaker made for protecting 120/240V electrical circuits from overloads and short circuits. It uses a thermal magnetic trip system, meaning it responds to both prolonged overcurrent situations and sudden fault conditions. In simple terms, it helps prevent overheated wiring and protects connected equipment when something goes wrong in the circuit. This 20 amp breaker features a 10kA interrupting capacity at 120/240VAC, making it suitable for many standard residential and commercial electrical systems. The bolt-on design provides a secure connection inside compatible NE frame panelboards, which is especially important in environments where a stable, fixed connection is preferred. Its molded case housing is designed to handle the normal demands of everyday electrical use, offering consistent performance over time. For electricians and maintenance teams replacing an existing unit, the NE221020 provides a straightforward solution that fits properly and performs as expected.
