HMA3175T - 175Amp Trip Unit

HMA3175T - 175Amp Trip Unit

When you’re replacing a trip unit in existing electrical equipment, the details matter. The HMA3175T is a 175-amp, 3-pole thermal-magnetic trip unit designed specifically for compatible MA and HMA frames. It has a magnetic Hi-Low trip setting range of 875–1750 amps and measures approximately 4.00" W x 7.50"L x 3.50"D. That combination of frame type, amperage, pole configuration, dimensions, and trip range makes the HMA3175T suitable for applications where this particular form, fit, and function are required.

Material Compliance and Certifications

Material-compliance details and specific agency certifications were not provided in the available product information. Certifications such as UL, CSA, RoHS, or other standards should therefore not be assumed.

If your installation requires a specific certification or compliance standard, check the markings on the component and confirm it meets the requirements for the equipment and application.

Where It Works Best

The HMA3175T makes the most sense in maintenance and replacement situations involving compatible MA or HMA circuit breaker frames. It is particularly suited to legacy electrical systems where keeping the original equipment configuration and specified trip characteristics is important.
