NA3P100 - 100Amp Circuit Breaker

NA3P100 - 100Amp Circuit Breaker

The Schneider Electric NA3P100 100 Amp circuit breaker is built to provide dependable overcurrent protection in Stab-Lok electrical panels. Rated for 240 volts AC and configured as a three-pole breaker, it’s designed to protect three-phase circuits from overloads and short circuits before damage can occur. With a 10kA interrupting rating, this breaker is capable of safely interrupting high fault currents, helping protect connected equipment and wiring. Its plug-in design allows for a secure fit in compatible panels, making installation straightforward for licensed electricians and maintenance professionals working in residential, commercial, or light industrial environments. This breaker uses a thermal-magnetic trip system, meaning it responds to both prolonged overload conditions and sudden short circuits. The clearly marked 100A handle makes identification simple during service or inspection. Manufactured by Schneider Electric, the NA3P100 is a practical replacement option when maintaining or upgrading existing Stab-Lok panelboards that require a 3-pole, 100 amp configuration.
