FAQs
This motor is designed for hazardous environments with Exdb flameproof protection and IP55 ingress protection. It fits standard 315 frame mounts and can be integrated with common motor starters and VAR or VSD systems. Ensure terminal box location at D-End top and verify cable gland accessories meet zone 1/2 installation standards for safe field wiring and quick commissioning.
The motor is rated for IE2 efficiency and operates under a 2-pole, single-speed configuration suitable for continuous duty (S1). Voltage code D supports standardized connections, and the insulation class IC411 provides reliable operation up to ambient 50 °C. For hazardous zones, confirm motor control compatibility with your drive and proper cooling to maintain performance.
Yes. The 315 frame with cast iron construction offers high mechanical stiffness, good heat dissipation, and durable bearing configuration (6316/C3). Combined with Exdb protection and IP55, it supports sustained operation under difficult conditions typical of mining, cement, and chemical processes, reducing vibration-related wear and maintenance costs.
Key certifications include Exdb flameproof protection, IP55 ingress protection, IC411 insulation, Gas Group IIB, and Temperature Class T4 for elevated ambient conditions up to 50 °C. These features ensure compliance with ATEX/IECEx requirements and enable safer operation in hazardous areas.
With a robust cast-iron frame and flameproof design, maintenance intervals are longer due to greater protection against dust and moisture. IE2 efficiency reduces operating costs over time, contributing to a favorable ROI. Consider standard ABB maintenance practices, periodic bearing checks (6316/C3), and ensuring correct alignment with drives to maximize life cycle savings.
