NA2P100 - 100Amp Circuit Breaker Description

Material Compliance and Certifications
The supplied specifications did not include specific material compliance information or certification details for this breaker. Check the markings on the supplied product and confirm that its ratings and approvals meet the requirements of your equipment, installation, and applicable electrical codes.
Where It Works Best
The NA2P100 is intended for existing electrical equipment that requires this particular breaker configuration. It's a practical choice when replacing an existing NA2P100, and you need to match its 100 Amp rating, two-pole arrangement, Stab-On connection, physical dimensions, and 120/240VAC rating.
Before installing, compare the replacement breaker with the existing unit and equipment requirements. Check the part number, connection style, dimensions, poles, amperage, voltage, and AIC rating—not just one or two specifications. If there's any uncertainty about compatibility or installation, have a qualified electrical professional verify the application.
