Exd flameproof protection with IP55 enclosure provides safe operation in hazardous environments, reducing ignition risk and downtime while enabling use in chemical plants, refineries, and mining operations. The business impact is enhanced safety compliance and lower insurance costs, with a straightforward installation pathway thanks to the D-End top terminator box. The motor’s IE4 efficiency and full-load performance of 96.2% (50 Hz) translate into meaningful energy savings over long operating hours, supporting sustainability objectives and lower total cost of ownership for continuous-process applications. Cast iron frame, 355 size, and bearings 6322/C3 with 6316/C3 NDE deliver rugged durability and long service life, minimizing spare parts and maintenance events in heavy-duty duties. The IC411 insulation and IP55 protection ensure reliable operation at ambient up to 50 °C and altitude up to 1000 m, enabling deployments in constrained plant layouts and space-limited installations. With a 6-pole design and Exdb protection for gas group IIB, this motor balances performance and safety for pump, fan, and compressor drives in hazardous zones, reducing energy waste and improving system responsiveness in demanding processes. The combination of a robust frame, standard electrical designation M2JAP, and 355 SMB sizing supports straightforward integration with existing automation architectures and drive systems, delivering faster commissioning and consistent performance across shifts.

FAQs
The motor uses a D-End top terminator box, supports 355 frame mounting, and is built in cast iron for durable field service. It is certified Exdb flameproof and IP55 protected, making it suitable for Zone 1/Division environments. Plan for compliant cable routing, suitable enclosure, and proper enclosure rating in your control cabinet to ensure safe operation and easy maintenance.
This motor meets IE4 efficiency (Full Load 100% 96.2%, Partial Load 75% 96.3%, Partial Load 50% 95.8%). It operates under S1 duty, meaning continuous operation at constant load, which supports predictable energy use and reliable long-term performance in process lines and ventilation systems.
Yes. The motor features Exdb flameproof protection and gas group IIB, with IP55 enclosure, enabling safe use in hazardous zones. This combination supports compliance for electrical equipment in explosive atmospheres, ensuring safe operation for pumps, fans, and compressors in oil, gas, and chemical industries.
Key certifications include Exdb protection, IC411 insulation, and IP55 enclosure. Insulation class ICLF and IEC-based standards support reliable performance at elevated ambient temperatures (up to 50 °C) and 1000 m altitude, while the 355 frame and IM classes IMB35 IM2001 indicate compatibility with common motor mounting and installation practices.
Cast iron construction and robust bearings (6322/C3, 6316/C3) extend service life and reduce maintenance cycles, while IE4 efficiency lowers energy costs over time. The combination of Exd/Exdb protection and a standardized design accelerates commissioning, reduces spare part variety, and improves uptime—delivering faster project payback in hazardous-zone process industries.
