Mitä eroa on räjähdyssuojattujen tasojen IIIB ja IIIC välillä?

IIIB and IIIC both serve as classifications for explosion-proof electrical equipment in dusty settings, with IIIC ranking above IIIB.

III	C	T 135℃	Db	IP65
III Pintapöly		T1 450℃	Ma	IP65
		T2 300℃	Mb
		T3 200℃
	A Syttyvät lentävät flokit		Da
		T4 135℃
			Db
	B Ei johtava pöly	T2 100℃	Dc
	C Johtava pöly	T6 85℃

In environments categorized as IIIA, IIIB, or IIIC, IIIC locations pose the greatest risk. IIIC explosion-proof servo motors are appropriate for use in IIIB dust environments, whereas IIIB motors are not intended for use in gaseous environments.

All explosion-proof servo motors are classified as IIIC, making them suitable for a range of dusty conditions.
