The rated voltage, rated current, power, and speed of explosion-proof motors are the same as those marked on ordinary motors. The difference is that YBX4 series non sparking motor has an explosion-proof mark Ex, which is basically displayed on the main junction box cover. Explosion proof motors use explosion-proof enclosures to separate electrical parts that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixture. Therefore, in environments where flammable and explosive gases, powders, and water vapor may be generated, reliable and safe explosion-proof motors are definitely the best choice.
