The Difference Between Explosion-Proof Motor And Ordinary Motor
1. Explosion-proof motors are generally used in flammable and explosive situations. 2. The sealing of explosion-proof motor junction box is better than that of ordinary motors. 3. The low protection level of explosion-proof motors is IP55, while ordinary motors have IP23, IP44, IP54, IP55, and IP56, so it can be distinguished from the shape. 4.
