M3452

Complete Braking Kit with Transistor and Resistor

M3575R Braking Resistor

Includes Transistor and Resistor

(For 230-480VAC applications below 22A, consider using a Bonitron M3545 Line Regen instead).

M3452 Complete Braking Kits are used with AC drives to allow full power braking and 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 an internal braking resistor to prevent overvoltage faults.


The M3452 Complete Braking Kits include both a braking Transistor and Resistor in one convenient enclosure. This reduces the amount of wiring necessary between two separate components and allows for a quicker installation, while maximizing production up-time.
