HMA3400T - 400Amp Trip Unit Description
HMA3400T - 400Amp Trip Unit
The HMA3400T is a 400-amp, 3-pole thermal-magnetic trip unit designed for compatible MA and HMA circuit breaker frames. When you're working with existing electrical equipment, replacing the trip unit with the correct match is important to maintain the breaker assembly's intended configuration. This unit is designed for thermal magnetic operation only for MA and HMA frames and features a magnetic Hi-Low trip setting range of 2000–4000. The compact dimensions of 4.00" W x 7.50"L x 3.50"D make it easier to compare the unit against the existing trip component before installation.
