Feature → Business Impact → Application: The GRND enclosure on the ABB 7B7308 provides robust protection against dust and moisture in general‑purpose shop environments, reducing field maintenance and extending motor life. This translates to lower breakdown costs for grinders and belt sanders, while maintaining consistent torque on 4-pole, single-speed operation. Application: ideal for belt sanders, buffers and light-production grinders where rugged protection and reliability are essential. Feature → Business Impact → Application: Direct on line starting eliminates the need for soft-start hardware or variable frequency drives on simple loads, cutting initial capital expenditure and simplifying control schemes. Application: suitable for line-start installations on standard 3-phase equipment, enabling quick commissioning in maintenance-reduced lines. Feature → Business Impact → Application: Foot-mounted, horizontal mounting with a 0.63 in shaft and compact dimensions (22.875 in L, 12.813 in H, 12.25 in W) enables rapid installation into existing bases and frames, reducing retrofit time and labor costs. Application: retrofits on grinders and lathes where space is constrained or legacy mounts are used. Feature → Business Impact → Application: Voltage flexibility (208/230/460 V) and 50/60 Hz compatibility provide cross‑regional operability, supporting multi-site manufacturing and spares consolidation. Application: global assembly lines and mixed-shore facilities. Feature → Business Impact → Application: 0 day lead time and active stock across multiple warehouses mitigate procurement risk and shorten time‑to‑production, improving project velocity and on-time delivery for capital projects. Application: new line starts and maintenance projects across testing or production floors. This 3-phase motor (50/60 Hz, 4P, 1500/1800 r/min) delivers predictable performance with a durable steel frame and Insulation Class B to support long service life in continuous-duty use.
