У чому різниця між газовибухозахищеними двигунами та пиловибухозахищеними двигунами

Gas explosion-proof motors are not suitable for environments requiring dust explosion-proof motors. This is due to the different national electrical explosion-proof standards they adhere to: gas explosion-proof motors comply with GB3836, while dust explosion-proof motors follow GB12476.

Motors that meet both these standards and pass tests for each can be referred to as dual-marked explosion-proof motors. These motors are versatile, allowing interchangeability in environments requiring either gas or dust explosion-proof standards.
