First, the third letter of the explosion-proof marking is also key to the difference. If the third letter is "e," then it goes without saying that the fourth letter is "d." This explosion-proof marking combined is Exed, which means that the cabinet body of the explosion-proof distribution cabinet is flameproof, and the components installed inside are increased safety type.。

2. Increased safety "e": An explosion-proof form of electrical equipment, which involves taking additional measures on electrical equipment to improve the level of safety, avoiding the possibility of dangerous temperatures, arcs, and sparks under normal operation or specified abnormal conditions.。

In simple terms, the interior itself does not generate dangerous temperatures, arcs, or sparks; it only improves the level of safety, such as increasing the waterproof rating.。The internal components must carry Ex-marked components (explosion-proof components).。

2. As a wiring chamber, the entry devices for flameproof type "d" should be of type "d" (flameproof) entry, and its sealing rings are longer than those of the increased safety type. The entry devices for the increased safety type only need to achieve an improved level of safety.。

3. The flameproof type "d" enclosure needs to undergo a pressure test (IIB level: 1.5MPa/10 seconds pressure, IIC level: 2.0MPa/10 seconds pressure), while the increased safety type does not.。

4. The flameproof type "d" enclosure needs to undergo an impact test (an impact test where a test object weighing 1kg falls vertically from a height of 0.7m), while the increased safety type enclosure does not undergo an impact test.。
