ʻO wai ka Papa Pahū-Hōʻoia i ʻoi aku ke kiʻekiʻe, BT4 a i ʻole BT6

E like me nā kūlana aupuni no ka pale pahū uila, ʻo BT4 a me BT6 e hāʻule ana ma lalo o ka Papa IIB.

Pūʻulu wela o nā mea uila	ʻO ka wela ili i ʻae ʻia o nā mea uila (℃)	ʻO ke kinoea/māhu wela (℃)	Nā pae wela o ka mea pili
T1	450	＞450	T1~T6
T2	300	＞300	T2~T6
T3	200	＞200	T3~T6
T4	135	＞135	T4~T6
T5	100	＞100	T5~T6
T6	85	＞85	T6

Eia naʻe, the ‘T’ classification pertains to the temperature rating of explosion-proof electrical devices. Pono nā mea i hoʻokaʻawale ʻia ʻo T6 e mālama i ka wela o ka ʻili ma mua o 85°C, ʻAʻole pono ka T5 ma mua o 100°C, and T4 must not surpass 135°C.

The lower a device’s maximum surface mahana wela, the less likely it is to ignite atmospheric gases, thereby enhancing safety. No laila, the explosion-proof rating of BT6 exceeds that of BT4.
