P2100 - 100A Circuit Breaker

Need a P2100 circuit breaker for an existing residential electrical system? This new aftermarket breaker is a form-, fit-, and function-for replacement for the original P2100. It's a 100-amp, 2-pole, Type P bolt-on circuit breaker rated 10k AIC at 120/240VAC. Just as important, its dimensions, 1.5" high x 2.25" wide x 2.81" deep, are designed around the existing P2100 location in compatible equipment. For older installations, that matters. You're often not looking to change the entire setup; you need the right breaker configuration for the equipment already in place. This P2100 replacement meets that need while maintaining the required amperage, voltage, pole count, and bolt-on format. It's a straightforward replacement option, made for its intended application and built to last.

Material Compliance and Certifications

The available specifications for this breaker include no specific material compliance information, agency listings, or certifications. We don't want to assume certifications that haven't been documented.

If your installation requires a specific listing, approval, or material standard, check the breaker's markings and supporting documentation before installation. Also confirm the requirements of the existing equipment and applicable electrical codes.

Where It Works Best

This P2100 100 amp breaker suits compatible residential electrical equipment that requires the P2100's 2-pole, Type P, bolt-on configuration. It's particularly useful when you're working with an existing system and need a replacement that follows the original breaker's physical format and electrical ratings.

With older electrical equipment, the part number alone isn't the only detail worth checking. Before installation, compare the existing breaker and equipment requirements with the 100 amp rating, 2-pole configuration, 120/240VAC rating, 10k AIC, Type P designation, bolt-on connection, and physical dimensions listed above. Getting those details right helps ensure the replacement fits the intended application.

A qualified electrical professional should confirm installation and final compatibility and handle it in accordance with applicable electrical codes and equipment requirements.
