Flameproof Exdb protection and IP55 ingress safety are designed to minimize ignition risks in hazardous areas, supporting regulatory compliance and safer operation in oil & gas facilities or chemical plants. This translates to reduced downtime and a lower total cost of ownership as risk is mitigated and maintenance cycles can be extended. IE4 efficiency around 96.6–97.0% at 50 and 60 Hz reduces energy consumption during continuous S1 service, delivering measurable operating-cost savings on pumps, conveyors, and fans in harsh environments. The cast-iron frame (315) with IMB3 IM1001 improves durability and vibration resistance, enabling longer service intervals in demanding installations such as mining or processing lines. A 6-pole, single-speed configuration provides reliable torque and startup characteristics, while the ability to rotate on both sides offers installation flexibility in tight spaces. Exdb protection combined with Gas Group IIB compliance ensures regulatory alignment for hazardous-area drives, while a top D-End termination box streamlines wiring and reduces installation time in field deployments. The large frame and weight (1311 kg net) reflect rugged construction suitable for heavy-duty industrial applications, with dimensions that suit integrated plant layouts and OEM mounting patterns.

FAQs
This motor is designed for Exdb flameproof installations in IIB hazardous zones, with IP55 protection and IC411 insulation. Its D-End top termination box simplifies wiring in restricted spaces, and its 315 frame with a cast-iron body matches standard ABB mounting patterns, enabling straightforward replacement or retrofit in existing hazardous-area systems.
Key electrical specs include Exdb flameproof protection, IP55 ingress protection, IC411 insulation class, and IE4 efficiency. It runs on a 3-phase supply with a voltage code D, operating at 50 or 60 Hz, with 6 poles and a typical Full Load efficiency around 96.6–97.0%. Duty is S1, suitable for continuous operation.
Yes. The motor is rated for continuous, steady-state operation (S1) and is engineered to maintain stable torque and temperature under prolonged running. Its IE4 efficiency reduces energy consumption during long-running processes like pumps and mixers, delivering predictable operating costs in process plants.
Ideal for hazardous-area drives in oil & gas, chemical processing, mining, and heavy industrial installations. The flameproof Exdb certification, combined with IP55 protection and robust cast-iron construction, supports reliable operation in harsh environments while maintaining compliance with safety standards.
The unit features Exdb flameproof protection and Gas Group IIB suitability, IP55 ingress protection, IC411 insulation, and Temperature Class T4. It also conforms to hazardous-area installation practices and is built for high-durability, heavy-industrial use with a 315-frame, 6-pole configuration.
