SEPA24AT0100 - 100Amp Max. *Frame Only*

Keeping an existing electrical system running often comes down to finding the right replacement component. The SEPA24AT0100 is a 2-pole, 100-amp molded-case circuit breaker frame from the SE150 line, designed for use in compatible commercial and industrial power distribution equipment. This model features an electronic trip design and is supplied as a frame-only unit, making it a practical choice for maintaining equipment that already uses this breaker style.

Its interrupting capacity is rated at 100 kA at 480 VAC and 200 kA at 240 VAC, making it suitable for applications where a higher available fault current is present. Whether you're replacing a worn breaker frame during scheduled maintenance or repairing existing equipment, matching the original ratings and configuration helps keep the installation consistent with its intended design.

Instead of changing the system or modifying connected equipment, many maintenance teams need a breaker that is correctly suited to the application. The SEPA24AT0100 is built for that purpose. It offers the electrical ratings and physical configuration expected for compatible SE150 installations and is built to last in demanding commercial and industrial environments.
