the motor and bring about high temperature thus result in an ignition Therefore effective measures should be taken for all types of flameproof motors against sparks electricarcs and dangerous temperatures Ex d flameproof motor is a type of electrical apparatus operating in explosive zones its enclosure will be able to withstand an explosion of inflammable gas or vapour which penetrates into the internal part of it through any joints of structural openings openings furthermore this explosion will not cause ignition in the external explosive gas atmosphere formed by one or more types of gas or vapour M2JA Cast lron Totally enclosed Three Phase Flameproof lnduction MotorsM2JA Cast lron Totally enclosed Three Phase Flameproof lnduction Motors Location of Ex d EE MotorsLocation of Ex
