ABB 3GJA353420-HDCIN - 3-Phase Squirrel Cage Motor, Exdb
Part Number: 3GJA353420-HDCIN
Quick Summary
3GJA353420-HDCIN is a 3-phase squirrel cage motor designed for hazardous environments in industrial processes. Designers and procurement teams struggle to find Ex-protected motors that fit tight spaces without compromising safety or performance. This model integrates Exdb flameproof protection, IP55 enclosure, and IC411 insulation with IE2 efficiency to support regulatory compliance and energy savings. Its cast-iron frame, 355 size, 6 poles, and S1 continuous duty deliver durable torque for pumps, compressors, and mixers used in oil, gas, and chemical plants. Together with International standards compatibility and robust bearings, it reduces downtime and simplifies spares planning for harsh-site operations.

Exdb flameproof protection and IP55 enclosure provide inherent safety in hazardous areas, reducing risk and enabling compliant operation in oil, gas, and chemical plants. The strong cast-iron frame and high-load bearings deliver long service life, lowering maintenance frequency and total cost of ownership while supporting tough site conditions in offshore and onshore facilities. IE2 efficiency combined with a 6-pole, 355-frame design translates to meaningful energy savings in continuous-duty applications such as pumps and fans, contributing to a shorter ROI in process industries. The motor’s dimensioning supports straightforward installation alongside standard ABB and third-party starters, while the IC411 insulation and 1000 m altitude tolerance ensure reliable performance in hot, high-altitude environments. Built to handle 355MLB configurations with IMB35 IM2001 mounting classes, it offers predictable interchangeability and reduced downtime in critical systems.

FAQs
Install the Exdb flameproof motor within an Ex-rated enclosure and maintain IP55 integrity with proper sealing and gaskets. Place the termination box at the D-End top as specified, and use compatible cable glands and starters designed for hazardous zones. Ensure mounting conforms to the 355 frame size and leverages the 6-pole, S1 duty characteristics for continuous operation in oil, gas, and chemical facilities.
Exdb protection requires regular verification of flameproof integrity, including enclosure sealing, fastener torque, and gasket condition. Inspect insulation with IC411 ratings and monitor for signs of arcing or overheating. Maintain IP55 integrity during servicing, and use Ex-rated accessories and field-wiring practices to preserve hazardous-area safety margins and prolong motor life under gas-group IIB conditions.
Yes. The motor is rated for S1 continuous duty with an ambient temperature of up to 50 °C and operates at up to 1000 m altitude, making it suitable for hot sites and presses in chemical, petrochemical, and industrial processing environments. The 6-pole configuration provides robust torque for demanding loads while the IC411 insulation supports reliable operation under thermal stress.
Ideal applications include hazardous-area pumps, blowers, compressors, and agitation equipment in oil, gas, and chemical plants. The Exdb flameproof protection paired with IP55 protection ensures safe operation in zones with explosive atmospheres, while the 355-frame, cast-iron construction provides durability in harsh offshore and onshore environments, aligning with IMB35/IM2001 mounting practices.
The IE2 efficiency target delivers noticeable energy savings in continuous-duty applications, reducing operating costs over the motor’s life. Cast-iron framing and high-quality bearings extend service intervals and uptime, while Exdb protection lowers safety-related downtime in hazardous locations. Its standardized 355-frame size and compatible termination options simplify spares management and procurement, improving overall project ROI.
