NE221100 - 100Amp Circuit Breaker

NE221100 - 100Amp Circuit Breaker

The NE221100 100 Amp circuit breaker is designed to help protect 120/240V electrical systems from overloads and short circuits. With a 2-pole configuration and a 100A rating, it’s commonly used in panels that serve larger loads such as HVAC equipment, subpanels, and heavy-duty appliances. The built-in thermal magnetic trip mechanism reacts to both sustained overloads and sudden fault currents, helping prevent damage to wiring and connected equipment. Its bolt-on design creates a secure connection to the panelboard, making it a practical choice for maintenance, repair, or system upgrades where dependable circuit protection is required.

Key Features and Benefits

• 100 Amp, 2-Pole Design: Protects both legs of a 120/240V circuit.
• Thermal Magnetic Protection: Trips on overloads and short circuits for reliable performance.
• Bolt-On Mounting: Helps ensure a firm, stable connection inside the panel.
• Molded Case Housing: Built for long-term durability in everyday electrical applications.
• 10kA Interrupting Rating: Designed to handle fault currents up to 10,000 amps at 120/240VAC.
