Exdb flameproof protection with IP55 ingress protection and gas group IIB enables safe operation in explosion-hazard zones, reducing regulatory risk and enabling installation in Zone 1/2 environments. This directly reduces risk-related downtime and supports compliance with ATEX/IECEx requirements, allowing applications in chemical processing, oil & gas, and mining. IE4 efficiency at 50/60 Hz delivers substantial energy savings across continuous-duty cycles (S1), lowering operating costs for pumps, fans, and conveyors. The high-efficiency performance translates to lower CO2 emissions and improved sustainability metrics in long-running processes. ICFL insulation and a T4 temperature class enable reliable operation in hot environments up to 40 °C and at elevations up to 1000 m, improving uptime and reducing maintenance interventions in plants with variable ambient conditions. The cast iron 355 frame paired with bearings 6316M/C3 provides rugged durability and vibration resistance, extending service intervals and reducing total cost of ownership in dynamic industrial settings. A two-pole, 2-pole design with Exdb protection and gas group IIB supports strong starting torque and robust performance under continuous operation, while offering flexible mounting and rotation directions to fit diverse layouts. The D-End top terminator box and standard 1-piece unit design simplify installation, wiring, and field service, helping maintenance teams shorten commissioning time and minimize downtime during upgrades or replacements.

FAQs
This motor uses Exdb flameproof protection with IP55 ingress protection, suitable for explosive atmospheres. Ensure installation follows ATEX/IECEx zone classifications and maintain proper clearance around the D-End top terminator box. Use a compatible VFD or soft starter rated for hazardous environments and verify conductor sizing and grounding per local electrical codes.
IE4 efficiency is maintained across both 50 Hz and 60 Hz operation. At 50 Hz, full-load efficiency is typically around 97.2%, with high-load performance remaining stable at 75% and 50% loads. At 60 Hz, full-load efficiency is about 97.0%, with partial-load values around 96.8% at 75% and 96.2% at 50%. Expect strong energy savings in continuous duty (S1) applications.
Yes. With Exdb flameproof protection, IP55 ingress protection, Gas Group IIB rating, and ICFL insulation, the motor is designed for hazardous-area applications in chemical processing, oil & gas, and mining. It supports reliable operation in challenging atmospheres while meeting stringent safety and performance standards common in these industries.
Key certifications and ratings include Exdb flameproof protection, IP55 ingress protection, Gas Group IIB, ICFL insulation, Temperature Class T4, IE4 efficiency, and IECEx/ATEX compatibility. It is rated for ambient 40 °C and up to 1000 m altitude, with a robust 355 cast-iron frame suitable for demanding industrial environments.
Expect reduced downtime due to rugged cast-iron construction, Exdb protection, and reliable S1 duty operation. The motor’s high IE4 efficiency lowers energy costs, contributing to a faster ROI over its service life. Plan for periodic inspection of bearings (6316M/C3) and verify seal integrity in hazardous zones during routine maintenance.
