ABB 3GJA312840-HDDIN 3-Phase Squirrel Cage Motor - Exdb

Exdb flameproof protection is built into the motor, enabling safe operation in IIB gas groups and preventing ignition sources during startup and operation. This translates to lower safety risk, reduced incident costs, and smoother regulatory audits for plants handling flammable liquids or gases. In real-world installations such as refineries, chemical plants, and offshore platforms, this motor helps maintain continuous production without compromising safety. IP55 enclosure and IC411 insulation discipline external dust ingress and internal heat buildup, delivering reliable performance even at 50 °C ambient and up to 1000 m altitude. The result is fewer deratings and longer intervals between maintenance, which lowers lifecycle costs and extends asset life. Operators benefit from predictable running temperatures and steadier torque across loads. With a cast iron frame size 315 and a 4-pole design, the motor delivers robust mechanical strength and stable torque. The D-end top terminator box simplifies field wiring and reduces installation time, while the 6319/C3 bearing with 6316/C3 NDE supports durable operation in challenging environments. IE3 full-load efficiency ratings around 96% at 100% load and similar performance at partial loads (96.2% at 75% and 95.8% at 50%) translate to measurable energy savings and lower operating costs. The motor also carries a Customs Tariff Number 85015381, facilitating import processes and compliance checks. The product’s 315 frame and 1646 kg net weight reflect robust construction suitable for demanding industrial duty. Compatibility with standard electrical interfaces and ABB design practices supports quicker integration with existing drives and control systems, reducing commissioning risk. With a minimum order quantity of one piece and a selling unit of measure in piece, procurement can precisely balance inventory and maintenance budgets. In short, this motor pairs safety, efficiency, and reliability for hazardous-area applications. Additionally, its rugged construction supports long service intervals, improving return on investment.
