Flameproof Exd protection provides inherent safety in explosive atmospheres, lowering ignition risk and ensuring regulatory compliance for hazardous-area installations. This translates to safer start-ups, fewer unplanned outages, and extended motor life in oil, gas, chemical, and mining environments. The IP55 rating and IC411 insulation guard against dust, moisture, and thermal stress, delivering dependable performance at ambient up to 50 °C and altitudes up to 1000 m, with minimal derating in real-world conditions. A 2-pole, 315 mm frame offers high starting torque while maintaining a compact footprint and standard mounting compatibility for retrofit projects and new builds. IE2 efficiency at full load (94.6%) reduces energy costs and CO2 footprint, supporting sustainability goals. Cast iron construction and a reinforced bearing system (6316/C3) enable long service intervals, even in demanding duty cycles, while Exdb protection and Gas Group IIB certification simplify regulatory approvals. The design accommodates a D-End top terminal box for straightforward wiring and safe access, reducing installation time in constrained spaces. Overall, this motor balances rugged reliability with efficient operation, helping users optimize uptime and total cost of ownership in hazardous-area processes.

FAQs
Plan for a 315 mm frame installation with adequate space for mounting bolts and service clearances. The terminator box location is D-End top, which affects wiring access and enclosure sealing. Use proper cable glands and seals to maintain IP55 integrity, and ensure balanced foundation to support the 940 kg weight and minimize vibration during initial energization.
Yes. The motor features Exdb flameproof protection, IP55 ingress protection, and Gas Group IIB with Temperature Class T4. It is designed for continuous S1 duty in hazardous zones, and its insulation class ICFL/IC411 support stable operation under elevated temperatures, helping you meet ATEX/IECEx certifications with confidence.
This is a 2-pole, 3-phase motor with IE2 efficiency (Full Load ~94.6%). It uses Voltage Code D and supports S1 duty, suitable for continuous operation. The motor is designed for Exd flameproof service, with Exdb protection and a robust bearing arrangement (6316/C3), ensuring reliable performance in challenging environments.
The cast iron frame and bearing assembly (6316/C3) provide rugged durability and long service intervals, reducing maintenance frequency and spare parts consumption. A top-access terminal box (D-End) simplifies field wiring, saving commissioning time. Combined with high efficiency IE2 performance, operating costs decrease over the lifecycle, contributing to lower total cost of ownership in hazardous-area processes.
Ideal for chemical processing, petrochemical, mining, and heavy paint/finishing operations where explosive atmospheres are present. Its flameproof Exd protection, IP55 sealing, and 315 frame compatibility enable reliable, compliant operation in ATEX zones, supporting uptime targets and safety standards in demanding environments.
