General Information
M2JAX Series Flameproof Three-phase Induction Motors
M2JAX series flameproof three-phase induction motors for Explosive atmospheres with "Ex d" type of protection, are designed for "Ex d ll C T4 Gb" grade as standard. Motors are extensively applied in chemical, oil and gas industries. The motor enclosure will be able to withstand an explosion of inflammable gas or vapour, which penetrates into the internal part through joints of structural openings. Furthermore, no internal explosion can be transmitted to the explosive atmosphere surrounding the motor. M2JAX series flameproof motors meet the standard of IEC60079- 0:2007/IEC60079-1:2007 and GB3836.1-2010/GB3836.2-2010. It is certified by CQST and the efficiency rating reaches IEC IE2, which is in accordance with China Grade 3 efficiency standard.
