Frequently Asked Questions

Q: What does the MA 80 trip unit designation mean?
A: MA indicates Thermal-Magnetic Adjustable protection. The 80 refers to the adjustable range, allowing thermal trip customization from 0.7 to 1.0 times the rated current (112A-160A) to match specific load profiles.

Q: Can this MCCB be used for motor protection?
A: Yes, the adjustable thermal trip makes it ideal for motor circuits. Set the thermal adjustment to accommodate motor starting currents while providing overload protection during normal operation.

Q: What accessories are compatible with this model?
A: Compatible accessories include auxiliary contacts, shunt trips, undervoltage releases, motor operators, and padlocking devices. All TMAX XT accessories are field-installable.

Q: How do I verify the breaking capacity for my application?
A: The 50kA Icu rating at 400V ensures protection for most industrial applications. Verify your system's prospective short-circuit current is below this value through fault level calculations.
