Specific Purpose Motors/Explosion Proof Motors/EP Series – 3 Phase Standard Efficiency (IE1) Explosion Proof Induction Motors

EP Series – 3 Phase Standard Efficiency (IE1) Explosion Proof Induction Motors

Categories: ,

EP series three phase explosion proof motors are uniquely designed and built to contain the sparks within the motor to prevent ignition of external combustible vapours contained in the surrounding atmosphere. The explosion proof characteristic enables the motor to be safely used in hazardous environments.
