ABB KBM3454 Short Series Brake - CSA UR
Part Number: 7BKBM3454
Quick Summary
ABB KBM3454 Short Series Brake provides reliable braking for 3-phase motors in compact drive systems. Engineers often struggle with precise stopping, startup surges, and retrofit limits in space-constrained panels. This unit carries CSA and UR certifications and RoHS compliance, with a NEMA design B enclosure and a 56C frame that fits common ABB drive ecosystems. By integrating a 0.25 HP brake at 60 Hz across 208-230/460 V supplies, you gain predictable stopping performance, reduced wear, and improved downtime. The solution supports efficient component sourcing, quick installation, and scalable performance across conveyors, machine tools, and packaging lines. Engineered for durability, it also features regreasable bearings and a robust, serviceable design to minimize lifecycle costs.

The KBM3454 uses a compact 56C frame with a C-Face drive end flange, enabling easy bolt-on integration in horizontal mounting configurations. This compatibility reduces retrofit complexity and accelerates installation in space-constrained panels, delivering faster time-to-value for packaging machinery and small conveyors. The 0.25 HP brake delivers predictable stopping torque at 1725 r/min on a 3-phase, 60 Hz supply (208/230/460 V), which translates to smoother cyclic operation and lower wear on driven equipment. With a Direct On Line start and a TENV enclosure, operators benefit from reliable performance in typical workshop environments while maintaining safety and compliance through RoHS and NEMA design B standards. Lubrication is regreasable, and bearings are 6203 ball type, extending service life in high-cycle applications. The motor base is footless, and mounting orientation is horizontal, simplifying retrofits and reducing mounting hardware requirements. Stocking at multiple warehouses (US, GB, SG, CN) supports shorter lead times and reduced downtime, while the ABB designation (KBM3454) ensures seamless integration with Baldor-Reliance brands and ABB drive ecosystems. Expect measurable improvements in uptime, energy efficiency, and overall maintenance costs in conveyor lines, packaging cells, and light manufacturing automation.
