Material Compliance and Certifications

Specific material compliance, agency certifications, or listing information was not provided in the available HMA3150 specifications. Certifications or compliance with standards such as UL, CSA, RoHS, or other regulatory requirements should therefore not be assumed based solely on the part number or electrical ratings.

For installations where a particular certification, listing, or material-compliance requirement applies, verify the markings on the breaker and confirm they meet the requirements for the equipment and application.

Where It Works Best

The HMA3150 150 Amp circuit breaker is best suited for compatible electrical distribution equipment that specifically calls for an HMA-type, 3-pole, 150 Amp thermal-magnetic breaker with an interchangeable trip unit. It is particularly relevant when maintaining existing or legacy electrical systems where preserving the original form, fit, electrical ratings, and intended function is important.
