Procurement fit

The D5H is rated Ex db IIB T4 Gb, and the D5L is rated Ex db eb IIB T4 Gb. Both series cover frame sizes 355 to 450, with documented output up to 770 kW. Procurement should confirm pole count, cooling arrangement, mounting form, and ambient rating against the current manufacturer datasheet, since these parameters influence the achievable power and the certification envelope at the point of order.

Technical capabilities

The D5H applies flameproof enclosure (Ex db) protection, designed to contain an internal ignition. The D5L combines flameproof enclosure with increased safety terminal boxes (Ex db eb), treating the termination compartment under a separate protection concept. Both series share gas group IIB, temperature class T4, and equipment protection level Gb. The 355 to 450 frame span and 770 kW upper limit define the catalogue envelope as documented.

Markets and applications

Motors rated IIB T4 Gb are typically specified for hazardous areas in oil and gas, petrochemical, and chemical process plants where the gas grouping and surface temperature limits are met. The available documentation does not enumerate specific application verticals, reference installations, or end users for the D5H or D5L series. Suitability for a given site should be confirmed against the actual site classification and applicable regional standards.

Evidence limitations

Several common buying fields are not publicly documented in the source material. Voltage, frequency, speed, efficiency class or IE rating, insulation class, ingress protection, mass, overall dimensions, permissible ambient temperature, sound level, and bearing arrangement are not publicly documented. Approvals beyond the ATEX Ex db and Ex db eb markings, service factor, starting method, and warranty terms are not publicly documented.
