HMA3500 - 500Amp Circuit Breaker

HMA3500 - 500Amp Circuit Breaker

The HMA3500 is a 500-amp, 3-pole thermal-magnetic circuit breaker designed for electrical systems that use the HMA breaker configuration. When you're replacing equipment in an existing system, the right match comes down to more than just amperage. This breaker features a 40°C rating, an interchangeable trip unit, and load-side terminals included. It is rated at 25k A.I.C. at 600VAC, 35k A.I.C. at 480VAC, and 65k A.I.C. at 240VAC, giving technicians the information needed to compare it with the existing installation.

Material Compliance and Certifications

Specific material compliance information, certifications, and agency listings were not provided for the HMA3500. UL, CSA, RoHS, or other certification claims should not be assumed without confirmation.

If a project requires a specific certification or compliance standard, verify the markings on the breaker and review the applicable equipment documentation before installation.

Where It Works Best

The HMA3500 500 Amp circuit breaker is a good fit for existing electrical equipment that requires an HMA-type, 3-pole thermal magnetic breaker with matching electrical and physical specifications. It is especially useful for maintenance applications where keeping the existing system configuration is important.

For replacement work, start with the details that define compatibility: HMA type, 500 Amp rating, three-pole configuration, voltage, A.I.C. rating, trip unit arrangement, dimensions, and terminal setup. A careful comparison helps ensure the replacement fits the equipment as intended and maintains the original breaker configuration.
