Exdb flameproof protection and IP66 enclosure deliver enhanced safety and compliance in hazardous environments, reducing ignition risks and costly downtime while supporting regulatory requirements for mining and surface processing. This translates to lower total cost of ownership as maintenance windows shrink and service intervals extend. Cast-iron frame and a robust 250 frame size provide exceptional mechanical integrity for harsh, dirty environments, enabling longer service life and reliable operation in mining drives and pumps. Bearings rated 6315M/C3 with IMB5 IM3001 support steady operation at elevated loads, helping plants maintain consistent torque and output. The IE2 efficiency rating (Full Load 94.2%, Partial Loads 93.7–94.3%) drives meaningful energy savings across long-running shifts, contributing to lower operating costs. Top-entry terminator box simplifies wiring during install and service, while a 1000 m altitude and 40 °C ambient rating ensure predictable performance in challenging locations. With a 2-pole design and S1 steady-state operation, this motor suits continuous duty applications, reducing the need for frequent replacements. Overall, the combination of safety features, rugged construction, and efficiency translates into improved uptime, safer hazardous-location performance, and a lower total cost of ownership for mining and heavy industry equipment.

FAQs
This model uses a top-entry terminator box to simplify cable routing and service access during installation and maintenance. With a 250 frame, cast-iron housing, and IMB5 IM3001 bearing arrangement, ensure correct alignment and secure mounting on a rigid base. Configure rotation direction to match drive requirements and verify electrical connections follow the included wiring diagram for hazardous locations.
The motor provides IE2 efficiency with Full Load around 94.2% and Partial Load values near 94.3% at 75% and 93.7% at 50% load. These figures translate to meaningful energy savings over long duty cycles typical in mining and continuous process drives, while maintaining stable torque output and thermal performance within the specified ambient and altitude limits.
Yes. The motor features Exdb flameproof protection and an IP66 enclosure, combined with IC411 insulation and Exd/Exdb certifications. It is designed for hazardous environments, including underground mining, where ignition protection, dust/water ingress resistance, and reliable operation are critical for safety and regulatory compliance.
Core certifications include Exdb explosion protection, Exd flameproof protection, IP66 enclosure, and IC411 insulation class. The unit is designed for mining and hazardous locations, with a top-entry design for safe, compliant installation. Altitude and ambient ratings (up to 1000 m and 40 °C) support stable performance in demanding environments.
The ROI stems from energy savings due to IE2 efficiency, reduced downtime from rugged cast-iron construction and high IP66/Ex protection, and lower maintenance costs thanks to long-bearing life (6315M/C3 and 6313M/C3). In mining and heavy industrial settings, these factors combine to lower lifecycle costs while improving safety and uptime across continuous-duty applications.
