Exdb flameproof protection provides safe operation in IIB gas environments, enabling reliable performance in hazardous-area applications such as chemical processing and oil & gas facilities, while reducing the need for frequent protective shutdowns. This translates to improved uptime and lower maintenance costs as certified equipment is less prone to field faults. IE4 efficiency delivers meaningful energy savings across continuous and variable-speed operations, with measured full-load efficiency near 97.4% at 50 Hz, supporting lower total cost of ownership over the motor’s lifetime. IP55 enclosure plus a rugged cast-iron frame delivers robust ingress protection and mechanical durability in dusty or wet plant conditions, reducing wear and tear in demanding environments. The 355 mm frame, 4-pole design, and IMB5 IM3001 classification enable reliable operation under heavy loads, while bearing configurations 6322/C3 and 6316/C3 support extended service intervals. Direction of rotation is available on both sides, offering flexible installation and simplified site commissioning. The Terminator Box Location at D-End top and a 0 pallet lift packaging level enable straightforward installation in tight plant spaces and streamlined logistics. Overall, this motor aligns with industry standards for hazardous-area motors and supports compliant procurement, lower total cost of ownership, and safer, more reliable plant operations.

FAQs
This 355 frame, 4-pole motor uses a cast-iron enclosure and IM Class IMB5 IM3001, making it compatible with common industrial mounting configurations. The Terminator Box Location is D-End top, which supports straightforward wiring in many control panel layouts. Direction of rotation is available on both sides, offering installation flexibility for pumps, fans, and conveyors in limited spaces.
The motor is Exdb flameproof, suitable for gas groups IIB, with IP55 protection and IE4 efficiency. These certifications support safe operation in hazardous environments such as chemical plants and oil & gas facilities, while providing energy efficiency benefits and robust ingress protection against dust and water.
IE Class IE4 performance data shows Full Load (100%) at 50 Hz is 97.4%, with Partial Load (75%) at 97.4% and Partial Load (50%) at 97.1%. At 60 Hz, Full Load is 97.1%, Partial Load (75%) 96.9%, and Partial Load (50%) 96.2%. These figures support reliable energy budgeting across standard industrial operating conditions.
The motor uses a Cast Iron frame with Frame Size 355 and bearing configurations 6322/C3 (drive end) and 6316/C3 (non-drive end). Net dimensions are 1584 mm (length) x 1077 mm (height) x 800 mm (width) with a net weight of 2190 kg. The Terminator Box Location is D-End top, aiding accessible wiring and serviceability in tight spaces.
Hazardous-area applications in chemical processing, oil & gas, mining, and water treatment benefit from Exdb flameproof protection, IP55 sealing, and IE4 efficiency. The combination reduces risk of ignition, extends mean-time-between-failure, lowers energy costs, and improves overall ROI through safer operation and lower maintenance and energy expenses.
