ABB 3GJA312850-ADDIN 3-Phase Squirrel Cage Motor - Exd

Exdb flameproof protection is a core feature that enables safe operation in potentially explosive atmospheres across industries worldwide and across multiple site installations. This protection class minimizes ignition risk during startup and shutdown sequences in Zone 1/21 environments. Together with IP55 sealing and IE3 efficiency, the motor supports regulatory compliance and measurable energy savings. The 315 cast-iron frame provides rugged durability suitable for harsh factory floors and outdoor installations, and resists vibration in high-duty cycles. IP55 protection protects against dust ingress and water splash, while insulation class ICLF maintains performance at elevated temperatures even in dusty environments subject to cleaning cycles and periodic humidity. A temperature class of T4, ambient rating up to 50 °C, and 1000 m altitude ensure reliable operation across diverse geographic sites with variable ambient conditions. IE3 efficiency coupled with a 4-pole design delivers high efficiency at full load and low energy costs even under peak production schedules. Full-load efficiency is specified at 96.0%, with strong partial-load performance that supports variable-speed or constant-torque applications across variable process loads and equipment configurations. This translates into significant operating savings for continuous S1 duty cycles in production lines and helps justify capital expenditure through faster ROI. The motor uses high-quality bearings (6319/C3 and 6316/C3) and a precise IMB3 IM1001 mounting class for longevity even under frequent thermal cycling and vibration. D-end top terminator box simplifies cable entry and maintenance, reducing installation time and field wiring errors which translates to improved commissioning and lower on-site risk. A robust cast-iron frame and 315 frame size support secure mounting in existing equipment footprints without requiring major structural modifications. Rotation direction is configurable on both ends, enabling flexible drive and gear-motor integration for reverse operation or multi-drive configurations. With Exdb protection and Gas Group IIB, it is well suited for hazardous-area processes including refineries, chemical plants, and mining operations. The Terminator Box Location at D-End Top streamlines wiring layouts and supplier handoff for maintenance teams and supports standardized service procedures across sites. Overall, the combination of rugged build, safety certifications, and energy efficiency supports long asset life while meeting industry standards and reducing maintenance spares. This translates to lower lifecycle costs, reduced downtime, and predictable procurement in regulated industries across multi-site operations and diverse process streams. For engineers and procurement teams, the ABB Exdb motor delivers a reliable backbone for hazardous-area automation that accelerates project timelines and improves return on asset investment.
