Feature → Business Impact → Application: Exdb flameproof protection delivers enhanced safety in hazardous environments, reducing risk of ignition and ensuring compliance with ATEX and IECEx standards. This translates into lower incident costs and simpler certification processes for oil & gas, chemical processing, and mining facilities, where flameproof motors are a regulatory requirement. Application: chemical plants and refineries with flammable atmospheres that demand reliable, certified equipment. Feature → Business Impact → Application: IE4 efficiency with Full Load 96.7% and even higher partial-load performance minimizes energy consumption, delivering measurable operating savings and faster ROI on motor upgrades across pumps, fans, and conveyors in continuous operations. Application: energy-intensive HVAC, process cooling, and material handling in petrochemical settings. Feature → Business Impact → Application: IP55 enclosure and IC411 insulation provide rugged protection against dust, moisture, and temperature fluctuations at up to 50 °C ambient and 1000 m altitude, reducing failure rates and maintenance cycles. Application: outdoor interfaces near quarries, mining belts, and offshore platforms. Feature → Business Impact → Application: Cast Iron frame (355) with bearing pairs 6322/C3 and 6316/C3 delivers reliable load handling and reduced vibration, extending bearing life and reducing unscheduled downtime. Application: heavy-duty drives for conveyors and pumps in demanding environments. Feature → Business Impact → Application: 4-pole, single-speed design with Exdb protection and reversible rotation (Both sides) provides installation flexibility and straightforward integration with existing belt and pulley systems. Application: general purpose, reversible drives in packaging, mining, and chemical processing. Pain-point mitigation: By combining robust enclosure, intrinsic safety, and high efficiency, engineers can simplify procurement, ensure compliance, and achieve predictable performance under harsh conditions.

FAQs
The 3GJA352420-ADEIN operates with common variable speed drives used to control 4-pole, IE4 motors. Its 355 frame and cast-iron construction support standard mounting patterns, while Exd flameproof protection ensures safe operation in hazardous zones. Voltage Code D indicates compatibility with typical 380–420 V systems, enabling straightforward integration with existing plant electrical infrastructure and soft-start controls to minimize mechanical stress.
This motor provides Exdb flameproof protection and IIB gas group rating, designed to prevent ignition in explosive atmospheres. Combined with IP55 enclosure, IC411 insulation, and IE4 efficiency, it meets stringent ATEX and IECEx requirements, reducing compliance risk and enabling safe operation in plants with flammable vapors or dust.
Yes. The motor is specified for ambient temperatures up to 50 °C and altitude up to 1000 meters, with an IP55 enclosure and IC411 insulation to withstand dust, moisture, and elevated heat. This makes it suitable for outdoor, indoor, or harsh indoor environments common in chemical plants, mining operations, and offshore facilities.
The motor uses a cast-iron frame (355) with bearings 6322/C3 and 6316/C3, aligning with IMB3 IM1001 class and providing robust load handling and reduced vibration. This combination supports extended bearing life, lower maintenance, and dependable performance under continuous operation in heavy-duty drives such as conveyors and pumps.
IE4 motors deliver meaningful energy savings due to higher efficiency at full and partial loads, translating to lower electrical bills over the motor’s life. In hazardous plants, the improved safety margins and reduced downtime further enhance ROI. When paired with Exd flameproof protection and reliable cast-iron frames, OPEX reductions from energy use, maintenance, and compliance overheads accumulate quickly, often offsetting initial procurement costs within a few years.
