Exdb flameproof protection reduces ignition risk in hazardous zones, delivering a safer operating environment for oil, gas, and chemical processing facilities. The tangible business impact is improved worker safety and reduced risk exposure, enabling regulatory compliance while maintaining high production uptime. This feature is ideal for Ex-rated installations in offshore platforms and refinery units, where flameproof motors are mandatory. IP55 enclosure further protects against dust and water ingress, extending service intervals and lowering maintenance labor costs in dusty or washdown-heavy environments. The combination of IE4 efficiency with robust cast-iron construction translates to meaningful energy savings and cooler operation under load, supporting lower energy bills and longer bearing life in continuous-duty applications. The 355 frame size with 6 poles delivers dependable torque for S1 duty cycles, while the Exdb design supports gas-group IIB environments, aligning with industry codes and installation standards. Industry-insight: using this motor with compatible VFDs can optimize startup currents and drive-sizing in confined spaces, minimizing panel footprint and wiring complexity in brownfield upgrades. This motor’s 1000 m altitude and 40 °C ambient rating make it a versatile choice for global sites, from downstream processing to confined offshore facilities, reducing total-cost-of-ownership while preserving reliability.

FAQs
Installers should ensure the 355 frame size and 6-pole configuration align with the driven load and available space. Use the D-End top terminator box for straightforward motor wiring, and verify IP55 enclosure integrity in dusty or washdown environments. Check altitude limits up to 1000 m and ambient temperature rating of 40 °C to maintain rated performance. When pairing with a VFD, select a drive with compatible insulation and EMC filters to preserve IE4 efficiency gains.
This motor features Exdb flameproof protection for hazardous areas, IP55 enclosure protection, and IC411 insulation with IE4 efficiency. It is designed for gas group IIB environments and is suitable for S1 duty. Compliance with international norms ensures safe operation in chemical, oil & gas, and mining applications, while the flameproof design supports installation in hazardous zones with robust protection against ignition sources.
Yes. The Exdb flameproof protection, gas group IIB rating, and flameproof construction make it suitable for hazardous-area drives in chemical plants, refineries, and offshore facilities. The IP55 enclosure provides ingress protection against dust and water, while IE4 efficiency supports compliant energy performance in continuous operation. When selecting for hazardous zones, confirm local codes and panel interlocks, and ensure proper cable glands and field wiring practices.
At 50 Hz, the motor adheres to IE4 efficiency with full-load performance around 97.0% and partial-load figures near 97.1% at 75% load and 96.9% at 50% load. At 60 Hz, full-load efficiency remains around 97.0%, with partial-load values approximately 97.0% at 75% and 96.4% at 50%. These figures support energy savings in continuous-duty applications and help with drive sizing and lifecycle cost projections.
The combination of a cast-iron frame, robust bearings (6322/C3 and 6316/C3), and a protected Exdb design yields longer bearing life and reduced maintenance intervals in challenging environments. IP55 protection minimizes ingress-related wear, while the flameproof construction lowers risk of ignition in hazardous zones. High efficiency (IE4) reduces energy costs over the motor’s lifecycle, contributing to lower total-cost-of-ownership and more predictable capital expenditure for plants and offshore facilities.
