Electrical compatibility and a compact footprint drive faster installations. With a single-phase 60 Hz input and dual voltage options (115/230 V), the BL3518 fits common automation panels without custom transformers, reducing wiring and installation time. The 56-frame with TEFC enclosure supports easy mounting on standard motors, simplifying retrofits for conveyors and machine tools. Rugged TEFC protection and a steel frame reduce corrosion risk and extend service intervals, boosting uptime in factory floors and packaging lines while maintaining performance under demanding conditions. Mounting flexibility with a foot-mounted base, horizontal orientation, and F1 mounting position minimizes layout changes and accelerates integration with existing motor plants. CSA/UR certification and adherence to NEMA design standards provide regulatory confidence, while the 115/230 V, 60 Hz capability supports reliable operation across multiple regional grids. Stock readiness, 0 day lead times, and a regreasable bearing design further reduce maintenance overhead and total cost of ownership.
