ABB 3GJA184420-BDCIN 3-Phase Squirrel Cage Motor - Exdb
Part Number: 3GJA184420-BDCIN
Quick Summary
ABB 3GJA184420-BDCIN is a 3-phase squirrel cage motor designed for flameproof, Ex-rated duties in hazardous plants. In practice, engineers often face unreliable performance and maintenance challenges in ATEX zones, where equipment must withstand demanding temperatures and rugged environments. This motor addresses those pain points with a cast iron frame, IP55 enclosure, and Exdb flameproof protection, plus insulation suited to IC411 and high-temperature ambient conditions up to 50 °C. The IE2 efficiency Class delivers meaningful energy savings on continuous-duty S1 operation, while an 8-pole design supports stable torque across global mains. This combination supports safer, compliant drive systems and reduces total cost of ownership on pump, fan, or compressor applications.

Feature → Business Impact → Application: Exdb flameproof protection provides enhanced safety in hazardous zones, reducing risk of ignition and enabling compliant operation in ATEX environments for chemical processing and mining. This translates to lower insurance costs and fewer downtime events, especially for pumps and compressors that run in flame-hazard areas. Feature → IP55 enclosure and IC411 insulation improve reliability in high-dust, high-temperature plants, delivering over-time performance with minimal maintenance; ideal for fans, blowers, and HVAC drives in oil refineries. Feature → 8-pole design offers robust torque and smoother startup, enabling stable operation for heavy-duty conveyors and pumps while meeting IE2 efficiency targets to cut energy bills. Feature → Cast iron frame and 180 frame size provide rugged mechanical stiffness and straightforward mounting compatibility with standard bases, reducing installation costs and facilitating retrofits. Feature → Exdb protection and gas group IIB compliance support lifecycle safety programs, helping maintenance teams meet regulatory requirements and extend motor life under continuous duty (S1) in demanding environments. Feature → Ambient temperature rating of 50 °C and altitude up to 1000 m ensure suitability for global installations, minimizing the need for site-specific adaptations and enabling a wider supplier footprint for spares and service.

FAQs
When installing this Exdb motor in ATEX zones, ensure proper flameproof enclosure integrity, correct mounting orientation (D-End top terminator box), and compliance with IP55 protection. Verify ambient temperature does not exceed 50 °C and that altitude remains under 1000 m. Use suitable couplings and anti-vibration mounts to preserve insulation and minimize mechanical stress on the 180 frame.
The motor is rated IE2 with full-load efficiency around 88.4%. At 75% and 50% load, efficiency remains near 88.4% and 86.9% respectively, supporting energy savings during variable-speed or constant-torque duty. This performance reduces running costs on pumps, fans, and compressors while meeting contemporary efficiency regulations.
Yes. The Exdb flameproof protection combined with IP55 enclosure is specifically designed for hazardous locations. It withstands dust and moisture ingress and is suitable for installations in chemical plants, refineries, and mining sites where safety certifications and robust protection are mandatory.
Key certifications include Exdb flameproof protection, IP55 enclosure, and IC411 insulation. The motor serves gas group IIB and is rated for flameproof Exd protection in hazardous areas, with an 8-pole, S1 duty rating and IE2 efficiency. It is built to meet robust industrial and safety standards for late-model motor drives.
ROI is driven by reduced downtime, improved safety compliance, and energy savings from IE2 efficiency. Exdb protection lowers ignition risk and simplifies maintenance planning in ATEX zones. While initial costs may be higher, the total cost of ownership decreases through longer motor life, fewer unscheduled outages, and lower risk of catastrophic incidents in hazardous environments.
