ABB 3GJA351220-ADEIN 3-Phase Motor - IE4 Exd Flameproof
Part Number: 3GJA351220-ADEIN
Quick Summary
ABB 3GJA351220-ADEIN is a 3-phase squirrel cage motor designed for hazardous-area pumping and processing applications. Engineers often struggle to source a motor that combines explosion protection with energy efficiency and reliable service life in tough environments. This model delivers IE4 efficiency, Exd flameproof and Exdb protection, IP55 enclosure, and IC411 insulation, all packaged in a rugged cast-iron frame. Designed for Indian-origin manufacturing, it supports ATEX/IECEx compliance and helps plant operators reduce energy costs, simplify procurement, and improve uptime across hazardous facilities. The result is a safer, more productive motor solution that aligns with broader automation goals and total cost of ownership for industrial plants.

Ex protection is a core feature of the ABB 3GJA351220-ADEIN, delivering Exd flameproof and Exdb gas protection in a sealed, IP55-rated enclosure. This combination minimizes ignition risk in hazardous zones and supports uninterrupted operation in environments with corrosive vapors and dust. In practice, engineers can deploy this motor in chemical processing lines, offshore platforms, and mining ventilation systems without compromising safety or performance. IE4 efficiency drives measurable business value. Full-load efficiency reaches about 96.5%, with 75% and 50% loads still within the IE4 band, reducing energy costs on continuous duty. Paired with a 2-pole design and continuous S1 duty, the motor delivers consistent torque and speed under varying process loads, helping plants meet energy targets and reduce total cost of ownership. Rugged mechanicals reinforce reliability. A cast-iron frame sized 355 with 6316M/C3 bearings supports long life in high-temperature, high-vibration installations, while the D-End top terminator box simplifies electrical connections and maintenance. The insulation class ICLF and insulation system withstands elevated ambient temperatures up to 50 °C, and the design tolerates 1000 m altitude without performance loss. Installation and maintenance are straightforward, with a minimum order quantity of one piece and standard 'selling unit' packaging. The motor is designed for ATEX/IECEx-adjacent procurement, ensuring supply chain compatibility in multinational plants. Operators benefit from predictable lead times, standardized mounting dimensions, and familiar ABB service networks for spare parts and routine servicing. Potential objections about cost or complexity are addressed by the motor's proven combination of protection, efficiency, and rugged construction. The result is lower downtime, fewer site interventions, and faster payback through energy savings and extended intervals between maintenance—values that matter when uptime directly affects production rate and safety records.

FAQs
ABB 3GJA351220-ADEIN is designed for Ex hazardous environments with Exd/Exdb flameproof protection and IP55 sealing. It supports ATEX/IECEx compliance, continuous S1 duty, and 50 °C ambient operation up to 1000 m altitude. The 355 frame in cast iron with a D-End top termination enhances vibration resistance and simplifies electrical connections in rugged plant floors.
Electrical performance comes from IE4 efficiency, with Full Load 96.5% and Partial Load figures of 96.3% at 75% and 95.7% at 50%. The motor is a 2‑pole, 3‑phase device rated for continuous S1 duty, with a D voltage code and IP55 enclosure. It operates reliably at 50 °C ambient and up to 1000 m altitude.
Applications span hazardous-area pumping, mixers, and conveyors in chemical processing, oil and gas, and mining where ATEX/IECEx compliance matters. The Ex protection plus rugged cast-iron frame resists vibration and corrosive environments while maintaining stable torque delivery. The motor’s 355 frame and IP55 enclosure support easy mounting to standard bases and safe operation in limited spaces.
Certifications and standards include Ex protection with Exdb and Exd flameproof, IP55 enclosure, IC411 insulation class, and IE4 efficiency. The motor is rated for Gas Group IIB and Temperature Class T4, suitable for 50 °C ambient and 1000 m altitude. This combination supports ATEX/IECEx compliance and helps satisfy industry safety and procurement criteria.
Maintenance and ROI considerations include a robust cast-iron frame, sealed bearings (6316M/C3), and Ex-protected internals that reduce unplanned downtime. IE4 efficiency lowers energy costs, delivering measurable savings over the motor’s life. With a 1 piece minimum order and straightforward installation, customers can streamline procurement and shorten time-to-value in hazardous facilities.
