1LE5003-1AB42-1FB4 — Siemens SIMOTICS XP 1LE5 ATEX Hazardous Area Motor
The Siemens SIMOTICS XP 1LE5 is the explosion-protected induction motor for Zone 1 and Zone 2 hazardous areas with flammable gas and vapour atmospheres (Group IIA, IIB, IIC), covering the complete ATEX and IECEx-certified motor requirements for Saudi Arabia's oil & gas, petrochemical, offshore, and chemical processing industries. Available in flameproof (Ex d) and increased-safety (Ex e) protection concepts in cast iron or aluminium frame from IEC 71 through IEC 315, the 1LE5 covers 0.25 kW to 355 kW for all Saudi hazardous area motor applications.
The flameproof (Ex d) concept machines end shields, terminal box, and frame joints to precise gap dimensions that contain any internal explosion without propagating to the surrounding atmosphere — allowing use in atmospheres of all gas groups including Group IIC (hydrogen, acetylene) present at ARAMCO LPG and hydrogen facilities. The increased-safety (Ex e) concept achieves explosion protection by eliminating ignition sources through enhanced insulation quality and rotor construction that prevents arcing under any fault condition. Both concepts are dual-certified to ATEX and IECEx standards, satisfying both EU and international market procurement requirements from a single motor certificate.
In Saudi Arabia, the 1LE5 is the ATEX motor specification for ARAMCO upstream and downstream processing, SABIC Jubail and Yanbu petrochemical facilities, Ma'aden mining complex, and ARAMCO offshore production infrastructure. Every 1LE5 is delivered with dual ATEX/IECEx certificates, temperature class documentation, and the complete Ex motor documentation package required by ARAMCO Engineering Standards for classified hazardous areas. The converter-duty ATEX variant for VFD operation satisfies IEC 60079-7 requirements for frequency converter-fed Ex e motors — a growing requirement as SINAMICS G120/G150 drives in Zone 2 enclosures replace fixed-speed starters at ARAMCO and SABIC pump stations.
Razz Middle East supplies 1LE5 ATEX motors with all certification documentation and ATEX area classification verification support.

Key Features & Benefits
- ATEX and IECEx dual certification satisfies both EU (ATEX Directive 2014/34/EU) and international (IECEx scheme) requirements from a single motor certificate, meeting ARAMCO and SABIC procurement specifications.
- Flameproof (Ex d) with precision-machined joint gaps contains internal explosions within the motor housing for all gas groups including Group IIC (hydrogen, acetylene) at ARAMCO LPG and hydrogen processing facilities.
- Increased-safety (Ex e) eliminates ignition sources through enhanced insulation and rotor design, providing Zone 1 protection in a smaller and lighter motor than equivalent Ex d motors.
- Gas group IIC flameproof (Ex d IIC) variant provides protection against the most ignitable industrial gases — hydrogen, acetylene — present at ARAMCO LPG, hydrogen, and acetylene handling areas.
- Temperature class range T1–T6 allows motor surface temperature to be matched to the auto-ignition temperature of the specific process gas in the hazardous area.
- Converter-duty ATEX variant with reinforced winding insulation and insulated bearings for VFD-fed operation satisfies IEC 60079-7 enhanced safety requirements for frequency converter-fed Ex e motors.
- High-ambient-temperature variants rated up to +55°C maintain full rated output in Saudi Arabia's Gulf coast and desert process plant environments without motor derating during peak summer operation.
Industrial Applications in Saudi Arabia
- ARAMCO crude oil and gas process pump motors at upstream and downstream facilities in the Eastern Province, where ATEX Zone 1 Ex d or Ex e certification and ARAMCO Engineering Standard documentation are mandatory.
- SABIC Jubail petrochemical plant pump, fan, and agitator motors in classified Zone 1 and Zone 2 process areas, where dual ATEX/IECEx certificates satisfy the project's ATEX equipment register.
- Ma'aden mining facility Zone 2 classified areas, where 1LE5 Ex e motors drive conveyors, fans, and pumps in areas with potential dust and gas hazards.
- ARAMCO offshore platform pump, compressor, and ventilation fan motors, where IP65 sealing and IIB/IIC gas group coverage satisfies both offshore corrosive environment and hydrocarbon atmosphere requirements.
- Saudi Aramco LPG and gas fractionation facility motors in Zone 1 areas classified for Group IIC gases, where only flameproof Ex d IIC certified motors satisfy the hazard classification.
- SINAMICS G120D decentralised drive packages in Zone 2 industrial areas, where converter-duty 1LE5 ATEX motors paired with Zone 2-certified drive enclosures create a complete VFD-motor solution.
- Chemical and industrial gas processing facility motors, where IECEx international certification satisfies Saudi chemical plant operator inspection and insurance standards.
