Exdb flameproof protection with IIB gas group provides a higher safety margin in hazardous zones, while maintaining continuous-duty performance. This reduces regulatory risk and downtime, making it ideal for chemical processing, oil & gas, and mining applications where safe operation is non-negotiable. IE3 efficiency delivers measurable energy savings across load profiles, with Full Load (100%) at 94.9%, 75% at 95.1%, and 50% at 94.7%, translating into lower operating costs and better long-termROI for plants running pumps and conveyors. The IP55 enclosure, combined with an ambient rating of 50 °C and altitude up to 1000 m, supports reliable operation in dusty, hot environments without derating or frequent cooling transitions. Cast iron 315 frame with 6319/C3 and 6316/C3 bearings delivers durable life in harsh plants, reducing maintenance cycles and overall lifecycle costs. Installation flexibility is enhanced by bidirectional rotation (Both sides) and a top-mounted D-End junction box, enabling space-efficient layouts and easier service access in cramped switchrooms or outdoor cabinets. All aspects—frame, insulation (ICLF), and construction—are designed to withstand industrial exposure while keeping downtime minimal and maintenance predictable.

FAQs
This motor uses Exdb flameproof protection and is rated for IP55 with a top-entry junction box option (D-End top). Plan for installation in Zones classified for gas group IIB, at up to 1000 m altitude and 50 °C ambient. Ensure compliant wiring practices, appropriate cable glands, and coordination with control cabinets designed for Ex-rated equipment. The rotation direction is configurable (both sides), which simplifies motor mounting in space-constrained footprints.
The motor complies with IE3 efficiency class. At full load (100%), efficiency is 94.9%. At partial loads (75%), efficiency is 95.1%, and at 50% load, efficiency is 94.7%. This performance translates to meaningful energy savings across typical process profiles such as pumps and fans in hazardous environments.
Yes. The Exdb flameproof protection, IIB gas group rating, IP55 enclosure, and robust 315 cast-iron frame are designed for hazardous-area applications common in chemical processing, refineries, and mining. Its IE3 efficiency supports cost-effective operation, while the ATEX/IECEx-aligned protections help ensure regulatory compliance and safer plant operations.
The motor uses durable components such as 315 cast iron frame, bearings 6319/C3 and 6316/C3, and insulation class ICLF, which contribute to extended bearing life and fewer unplanned outages. Routine inspections should focus on bearing wear, insulation integrity, and cooling efficiency. The design supports reliable operation in dusty and hot environments, reducing the likelihood of performance derating and enabling longer maintenance intervals.
Key certifications include Exdb flameproof protection, IP55 enclosure, and IE3 efficiency, with Gas Group IIB specific to hazardous zones. The motor is built with a 315 frame and cast iron construction, has insulation class ICLF, and a temperature class T4. Origin is India (IN), tariff number 85015381, and minimum order is 1 piece, aligning with standard industrial procurement practices for hazardous-area motors.
