Explosion protection Exdbeb ensures safe operation in Zone IIB environments, shielding equipment from ignition sources in hazardous areas. The flameproof rating paired with an IP55 enclosure minimizes ingress and guards critical components in demanding plants. This motor is well suited for chemical processing, mining, and offshore facilities where reliability is non-negotiable. IE3 premium efficiency reduces energy losses across full and partial loads, delivering meaningful operating-cost savings on long-running processes. In S1 duty at 50 Hz, the motor maintains near‑nameplate performance while helping facilities meet energy efficiency targets and sustainability goals. Cast iron frame size 355 provides robust mechanical integrity, vibration resistance, and long-term durability in harsh environments. The 400 kW output with 2 poles is designed for steady torque and reliable operation under demanding loads. Top-terminal box and a dedicated termination approach simplify wiring during installation and future maintenance. The D connection configuration, 500 V supply, and 50 Hz specification align with standard plant electrical architectures, while mounting with IMB5/IM3001 ensures quick alignment and service access. Designed to operate up to 1000 m altitude and 40 °C ambient, this motor supports reliable uptime in remote or hot climates. Insulation class ICLF and Ex protection plus Gas Group IIB provide regulatory compliance and insulation margins for demanding duties.

FAQs
For hazardous-area installations, plan for Exdbeb flameproof protection and IP55 enclosure to meet Zone IIB requirements. Use the top-terminal box and D-connection wiring layout to simplify initial wiring, commissioning checks, and future maintenance. Ensure mounting on IMB5/IM3001 bases with cast-iron frame 355 for vibration resistance and long service life in tough plant conditions.
Yes. The motor is rated IE3 for premium efficiency at 50 Hz and features Ex protection Exdbeb with IIB gas group, aligning with ATEX/IECEx-style hazardous-area compliance. The insulation class ICLF and ambient ratings further support regulatory and safety requirements in demanding environments.
Typical applications include chemical processing plants, mining operations, oil and gas facilities, and water treatment plants operating in hazardous zones. The 400 kW, 2-pole design with 500 V supply and IP55 protection supports robust drives in demanding process lines and heavy-duty duty cycles.
Maintenance benefits come from a robust 6316M/C3 bearing arrangement and a durable cast-iron frame that tolerate harsh climates. IMB5/IM3001 mounting compatibility, top-terminal access, and a 1000 m altitude rating simplify service intervals, reduce downtime, and support predictable maintenance budgets.
Ex protection Exdbeb plus IP55 enclosure provide ignition-protection and ingress resistance essential for Zone IIB environments. Together with ICFL insulation and IIB gas group certification, these features enhance reliability, safety, and compliance for hazardous-location operation, while supporting long service life and plant-wide safety standards.
