M3452-U1600CM14-R7

The Bonitron M3452-U1600CM14-R7 is a heavy-duty braking transistor designed for 575–600 VAC variable frequency drive systems requiring high-capacity regenerative energy control. Rated for 1600 A peak and 1200 A RMS braking current, this M14 open-chassis model monitors the VFD DC bus and transfers excess energy to an external braking resistor when voltage rises during deceleration or overhauling operation. Its 940 VDC braking level and 0.58-ohm minimum resistance support demanding industrial applications where reliable dynamic braking is essential. The standard R7 control board provides a straightforward hardwired control platform, while the high-current M14 construction makes this configuration well suited for large drive systems that need controlled stopping and protection from DC bus overvoltage faults.
