Increased Safety Motors
Ex 'ec', Ex 'eb'


Increased safety motors are specially designed to maintain surface temperatures during normal operations or while starting operations. A maintained temperature avoids the possibility of arcs, sparks or heat, which could lead to an explosion while operating in an explosive environment. The increased safety motors from LHP are designed to operate in Zone 1, Zone 2, Zone 21 & Zone 22 and Gas groups I, IIA, IIB & IIC and are suitable for the temperature classes up to T6. We provide a wide range of increased safety motors in the efficiencies IE2, IE3 and IE4, which comply with IS/ IEC/ EN 60079-7 standards.
