FAQs
This motor uses a D-End top termination box and a 355 frame with a cast iron enclosure, designed for Exdb flameproof duty. It supports standard mounting arrangements common to 355 mm frame motors and is compatible with typical industrial drives and control cabinets used in hazardous locations. Installation should follow local ATEX/IECEx and IEC standards, ensuring proper clearance around the enclosure and compliant cable glands for IP55 protection.
The motor delivers IE2 efficiency with full-load performance around 95.1%, and similar values at partial loads (75% and 50%). In steady operation, this translates to lower electrical energy consumption, reduced heat losses, and cooler operation, which collectively reduce energy bills and cooling requirements over the motor’s life. For plants running continuous duty, the savings compound over time, improving return on investment.
Yes. The 3GJA352420-HDCIN features Exdb flameproof protection and a Gas Group IIB rating, along with IP55 ingress protection. It is designed for explosive atmospheres and aligns with common regulatory requirements for chemical, petrochemical, and mining facilities. For maximum safety, verify local compliance and ensure correct installation practices, including enclosure integrity and certified cabling in hazardous areas.
The motor is specified for Exdb flameproof protection, IP55, and IC411 insulation, with Gas Group IIB and Temperature Class T4. It supports S1 duty, a 355 frame, and a cast iron frame, making it suitable for continuous operation in hazardous environments. Compliance with relevant IECEx/ATEX and regional standards should be confirmed during procurement, and documentation should be retained for audits.
Maintenance is typically driven by the harsh operating environment; the Exdb protection and IP55 rating help minimize ingress-related wear. The rugged cast iron frame and high-quality bearings (such as 6322/C3) support longer service intervals. ROI improves through energy savings from IE2 efficiency, reduced downtime due to robust protection, and lower total cost of ownership in hazardous-area applications.
