HMA3350T - 350Amp Trip Unit Description
HMA3350T - 350Amp Trip Unit
The HMA3350T is a 350-amp, 3-pole thermal-magnetic trip unit designed for compatible MA and HMA circuit breaker frames. When you're maintaining existing electrical equipment, finding the correct trip unit is often about matching the original specifications rather than changing the system. This unit is rated for thermal magnetic operation only for MA and HMA frames and features a magnetic Hi-Low trip setting range of 1750–3500. Its compact size of 4.00" W x 7.50"L x 3.50"D makes it easier to compare against an existing trip unit before replacement, while the approximate shipping weight of 6.00 lbs. provides a helpful reference for handling and installation planning.
