ABB 3GJA312830-ADP 3-Phase squirrel cage motor - Exdb

Exdb flameproof protection and IIB gas group characterize this motor, delivering intrinsic safety for Zone 1/II installations. The business impact is clear: reduced ignition risk and compliant operation under hydrocarbon loads, translating to lower maintenance costs and fewer unplanned outages. In practice, you’ll deploy this motor in chemical processing, oil and gas pipelines, and other hazardous environments where a robust, flameproof drive is non‑negotiable. The Exd protection also simplifies maintenance planning by allowing a single stock of parts and standard test routines for inspection during routine route checks. IE4 efficiency drives meaningful energy savings in continuous duty applications, while heat generation stays within safe limits. The result is lower utility bills, cooler equipment, and improved motor life, especially in fans and pumps that run around the clock. Combined with a 4-pole design and 315 frame, this motor matches standard VFDs and control panels for straightforward retrofits. Field engineers also benefit from predictable torque characteristics and reliable starting behavior in variable-load conditions. IP55 protection and an ICFL insulation class protect against dust ingress and harsh conditions, reducing field service intervals. Cast-iron frame delivers mechanical resilience under vibration and high temperatures, giving you longer intervals between replacements in demanding plants. The 1475 mm length and 654 mm width with 929 mm height align with common footprint requirements, while the 1643 kg net weight indicates a robust solution designed for endurance in challenging environments. Altitude up to 1000 m and ambient temperature up to 40 °C ensure consistent performance across sites. Straightforward mounting with a D-End top terminator box location simplifies wiring and maintenance in confined spaces. The 315 frame and 1643 kg net weight imply a heavy‑duty, serviceable package designed for long life in aggressive environments, while the gas‑group IIB classification supports safe operation around hydrocarbon processing equipment. This motor is compatible with standard industrial drives and protective relays, enabling seamless integration into existing automation architectures and preventive maintenance programs.
