Mana yang Lebih Aman Antara Suhu Tahan Ledakan T1 dan T6

In the field of explosion-proof equipment, the safety is significantly determined by the temperature classification of the device. The T6 classification, indicating the “maximum surface temperature,” represents the safest category within this range. This classification ensures that the surface temperature of the equipment is low enough to prevent igniting flammable gases, even those with a low ignition point. Conversely, T1, with the highest allowed surface suhu, poses the greatest risk in explosive environments.

Kelompok suhu peralatan listrik	Suhu permukaan maksimum peralatan listrik yang diizinkan (℃)	Suhu penyalaan gas/uap (℃)	Tingkat suhu perangkat yang berlaku
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

In explosion-proof equipment, the primary concern isn’t an internal component explosion, but rather the restriction of energy released from damaged internal components to prevent igniting gases in bahan peledak atmospheres. As per the “Design Specifications for Electrical Installations in Explosive and Fire Hazardous Environments”, the T6 level stands as the safest classification. Devices with T6 classification are effective in preventing explosions, especially in environments with low ignition point combustible gases, not to mention those with higher ignition points.
