FAQs
This motor uses a D connection and IMB5/IM3001 mounting suitable for hazardous areas. It is designed with a 6-pole, 355 frame and cast-iron construction, enabling secure rigid mounting in restricted spaces. Ensure compliance with local standards for Ex protection (Exdbeb) and IP55 ingress protection, and verify vertical clearance for servicing.
At 50 Hz the motor delivers 355 kW with IE3 premium efficiency and full-load performance around 95.8%. The class IE3 data remains strong at partial loads (75% and 50%), ensuring efficient operation across duty points. The motor is rated for 500 V and uses a 6-pole design to match typical industrial drives.
The Exdbeb flameproof protection with gas group IIB makes this motor ideal for chemical processing, oil and gas refining, mining, and heavy process industries. Its IP55 enclosure and high frame strength support long-life operation in dusty, humid, or wash-down environments, while the 355 kW rating covers large pumping, fans, and drives.
Key protections include Exdbeb flameproof protection for hazardous areas, IP55 enclosure for dust and water resistance, and IC411 insulation class for high-temperature endurance. The motor supports 50 Hz operation with a 355 kW output and gas group IIB specifications, aligning with stringent industry safety requirements.
Cast-iron frame and robust bearings (6322/C3) reduce wear and service interruptions, while IE3 efficiency lowers energy costs over the motor’s life. The D connection and durable mounting options simplify installation and retrofits, reducing downtime during upgrades and ensuring predictable maintenance cycles in hazardous-area facilities.
