3. Key Technical Specifications

4. Flameproof Characteristics & الشهادات

4.1 Flameproof Principle

Featuring Ex db flameproof construction, safety is ensured by two protective measures:

Flameproof enclosure (Ex d): Withstands internal explosion pressure and prevents flame propagation to the external hazardous atmosphere.

Surface temperature limitation (Ex b): Maximum surface temperature of all motor parts does not exceed the limit defined by temperature class (T4=135°C, T5=100°C, T6=85°C).

4.2 Applicable Hazardous Environments

6. Cross-Reference Order Codes with Major Global Brands

Below are equivalent order codes for ABB M3JP series flameproof motors against other leading brands, matched by power, أقطاب, flameproof rating and mounting:

7. إرشادات الاختيار & توصيات الاستبدال
8. Flameproof rating matching: Select according to gas group (IIB/IIC) and temperature class (T4/T5/T6) of the hazardous area. IIC motors can replace IIB, but not vice versa.
9. Efficiency selection: IE3 standard for general applications; IE4 premium efficiency for high energy-saving requirements.
10. طريقة التبريد: IC416 with separate fan recommended for VFD applications to avoid overheating at low speeds.
11. أبعاد التركيب: Strictly comply with IEC standard dimensions to ensure compatibility.
12. Certification requirements: Confirm required certifications for critical applications (CQST for domestic projects, IECEx/ATEX for international projects).
13. Replacement notes:

Ensure replacement power ≥ original and flameproof rating ≥ original.

Verify mechanical dimensions: ارتفاع رمح, قطر رمح, keyway size.

Confirm terminal box position and cable entry size match the original motor.

For special environments (marine, outdoor, humid tropical), select correspondingly configured models.
