Voltage compatibility and footprint: The brake is designed for 208-230/460 V at 60 Hz, enabling a single part to cross multiple panels and drives, reducing wiring variants and stocking requirements. Business impact: lower procurement complexity and faster project commissioning for conveyor lines and packaging systems. Application: suitable for 3-phase motor drives in line applications where space and flexibility matter. Enclosure and mounting: TEFC enclosure with frame size 56 and foot-mounted, horizontal orientation simplifies installation in tight machines and preserves alignment under vibration. Business impact: improved reliability and reduced maintenance overhead; Application: horizontal mounting on standard base motors in material handling equipment. Performance and efficiency: Rated at 0.75 HP, 1140 r/min with a 1.15 service factor and 77% efficiency, delivering predictable stopping torque with minimal energy waste. Application: drives with moderate continuous duty in environments requiring consistent brake response. Reliability and serviceability: Regreasable lubrication and 6203 ball bearings extend service intervals, while a standard drive end flange supports quick swaps. Business impact: lower total cost of ownership and easier spare parts management. Application: maintenance teams can plan preventive service around defined wear patterns for long-running lines.

FAQs
Installation starts with selecting frame size 56 and a horizontal mounting position (F1) on a foot-mounted base. Align the drive end flange to standard mounting patterns, secure with appropriate fasteners, and wire the 3-phase supply for 208/230/460 V at 60 Hz. Use the dimension diagram 34LY3108 for clearance and torque specifications, verifying rotor alignment during commissioning.
Confirm 3-phase power at 208 V, 230 V, or 460 V and a 60 Hz supply. Check rated currents of 3.3 A, 3 A, and 1.5 A (depending on voltage). Ensure insulation class B, power factor around 59%, and that the motor frame size is 56 with TEFC enclosure. CSA/UR certification confirms North American compliance prior to energizing.
Yes. The 7BBM3543 provides reliable holding torque and precise stopping at 0.75 HP with 1140 rpm, designed for continuous duty environments. With a service factor of 1.15 and TEFC enclosure, it supports long runtimes in packaging or conveyors, reducing misstarts and minimizing wear on drivetrains while maintaining production pace.
The brake carries CSA and UR certifications, ensuring compliance with North American electrical safety and performance standards. This verification reduces risk during procurement and integration, especially in regulated environments. The product origin is the United States, and the catalog number BM3543 anchors traceability across inventories and maintenance records.
