Bonitron M3452-U150CB7-A Heavy Duty Braking Transistor

Bonitron M3452-U150CB7-A Heavy Duty Braking Transistor is a high-current module in Bonitron's M3452 braking family, designed to absorb braking energy from large AC drive systems and enable controlled deceleration of heavy motors. It carries a braking current rating of 150 A (peak and RMS), making it suitable for substantial load braking in industrial applications. The M3452 line includes variants configured for 115–120 VAC drive controls (the U-series) as well as higher-voltage 575 VAC configurations (the C-series), reflecting Bonitron's range of fault-protected braking solutions. These transistors are commonly used with Bonitron braking kits and resistors to complete the energy-dissipation path in high-horsepower drive systems.
