Explosion Proof Motors specifications and applications

These motors are designed to withstand internal explosion pressure and prevent ignition sources from venting into the atmosphere.

Protection types include Ex d, Ex de, Ex e, Ex p, Ex nA, and dust-zone configurations depending on the application.

  • 1/4 to 11,200 HP
  • 200 V to 11 kV
  • ATEX / IECEx / CSA
  • Horizontal or vertical

Engineering considerations

Identical terminal-box replacement

Replacement motors can be designed with identical main and auxiliary terminal boxes to avoid site cable, terminal, and commissioning changes.

  • Match dimensions, cable connections, and terminal locations
  • Reduce shutdown risk during commissioning
  • Especially useful in brownfield replacements where cable routing is fixed

Hazardous-area replacement

Hazardous-area motor replacements require careful review because site classification and protection standards may have changed since the original installation.

  • Review IEC, IECEx, CSA, UL, and ATEX requirements
  • Confirm the new motor suits current site conditions
  • Applicable to LV, MV, and HV motors in oil, gas, and petrochemical plants
