Exdb flameproof protection and IIB gas group certification keep equipment safe in explosive atmospheres, aligning with ATEX and IECEx expectations. This combination reduces ignition risk and protects personnel while enabling compliant operation in zones where flammable vapors are present. The motor is designed around a cast-iron 280 frame and a robust 6-pole configuration suitable for continuous S1 duty in demanding installations such as chemical processing and mining. IE4 efficiency at 50 Hz and 60 Hz translates to meaningful energy savings during long-running cycles. The motor delivers Full Load efficiency around 96% at 50 Hz and 96.3% at 60 Hz, with strong partial-load performance, translating to lower operating costs and a smaller carbon footprint for conveyors, pumps, and mixers. IP55 enclosure protects windings and connections from dust and moisture, extending service intervals in harsh environments. Insulation class ICFL adds reliability in elevated ambient temperatures up to 40 °C and altitudes up to 1000 m, ensuring stable operation across global installations. Cast-iron frame, 280, and bearing 6316/C3 deliver rugged longevity under vibration and heavy loads. Terminator box location D-End top simplifies wiring in tight spaces and supports straightforward maintenance, while the 6-pole design ensures reliable speed control in S1 duty. Direction of rotation both sides and flexible mounting options accommodate a wide range of driven equipment. The minimum order quantity is 1 piece, with standard lead times for China-origin manufacturing, enabling rapid deployment across multiple sites.

FAQs
For ATEX/IECEx environments, install the Exdb flameproof motor with correct gland seals and wiring per local codes. Use the D-End top terminator box for convenient wiring access, ensure the IP55 enclosure is intact, and mount on a stable base with vibration isolation. Confirm the 6-pole, 280 frame alignment with the driven equipment and set rotation as required.
The motor achieves IE4 efficiency with Full Load around 96.0% at 50 Hz and about 96.3% at 60 Hz. Partial-load performance remains strong (approximately 95.9–96.2% at 50 Hz and 95.6–96.3% at 60 Hz). These figures support reduced energy costs in continuous S1 duty for pumps, fans, and conveyors.
Yes. The Exdb flameproof protection, IIB gas group rating, and IP55 enclosure make it suitable for hazardous-area applications such as chemical processing and mining. Its 6-pole, 280-frame cast-iron construction is designed for continuous operation (S1) in challenging atmospheres, delivering reliable performance with compliant safety characteristics.
Key certifications include Exdb flameproof protection and IIB gas group safety, IP55 ingress protection, IC411 insulation, and IE4 energy efficiency. The design also aligns with ATEX/IECEx excavation and motor standards, with durable construction and a D-End top terminator box to simplify compliant installation in hazardous zones.
The robust cast-iron frame and 6316/C3 bearings support long service life with reduced maintenance. IE4 efficiency drives lower operating costs, while the Exdb protection minimizes ignition risk and downtime. Overall, customers can expect lower total cost of ownership, easier compliance, and improved uptime across hazardous-area installations.
