The M3452 series is a heavy-duty braking transistor designed to prevent overvoltage faults in AC drives by shunting excess DC bus energy through a braking resistor. It supports input voltages from 230 to 690 VAC and braking currents up to 1600 A. The M3452-E300K6 variant operates with 380 VAC drives at a 620 VDC setpoint, rated for 300 A RMS and 300 A peak braking current with a resistance of 2.07 Ω. It measures 20.00" x 7.12" x 10.50" and is UL and CUL listed. The unit includes local status indicators, remote monitoring via EtherNet/IP and PROFIBUS DP, and Master/Slave capability for systems above 200 A. Control voltage options include 24 VDC with R7 and R7E configurations, though these are not UL listed. The "A" suffix indicates the basic enable control option.
Bonitron Braking Transistors are used with AC drives to allow full power brakingand eliminate overvoltage faults. This permits controlled braking and dramatically shortens motor stopping time. The M3452 works with Variable Frequency Drives (VFD) to monitor the DC bus. If overvoltage occurs, the M3452 shunts the excess energy through a braking resistor to prevent overvoltage faults.
