3hp explosion proof motor with rated voltage 380V, -20℃~40℃ ambient temperature, humidity ≤90%, "Y" connection and IEC, EX, ATEX certificates. This types of induction motor has the advantages of high efficiency, low noise, low vibration, safety and convenient maintenance.
Tips: Types of Explosion Proof Motor.
Increased safety motor:
It is a motor structure that does not produce arcs, sparks or dangerous high temperatures under normal operating conditions. Some mechanical, electrical and thermal protection measures can further avoid arcs under normal or approved overload conditions. Sparks or high temperature, so as to ensure its explosion-proof safety. Increased safety explosion-proof motors should be used at an ambient temperature of -20～40°C, or if the ambient temperature exceeds the above range, the manufacturer should mark the ambient temperature range on the outside plate. The tE time of the increased-safety explosion-proof motor should not be less than the time required for the thermal overload protection device to cut off the power supply of the motor when the rotor is locked.
