Good quality air switch purchase

The air switch is a commonly used safe electrical equipment in the home. The quality of the air switch is related to the safety of electricity in the home. Therefore, it is necessary to buy a good quality air switch. The following points can help to buy a high quality air switch.

1. The most preliminary method is to look at the weight of the air switch. Generally speaking, the high-quality air switch uses a flame-retardant PC plastic shell, and the internal use of pure copper wire, the more the number of turns, the heavier the quality.

2. Next, look at the arc-extinguishing hood inside the air switch. The arc-extinguishing hood is used to generate an arc when the circuit is short-circuited and overloaded. If the arc cannot be successfully extinguished, the phenomenon of ignition will occur. This is very important. Nine pieces of iron.

3. Whether the switch surface meter has IEC standard, CCC certification, Great Wall certification, PICC medium quality assurance certification, and whether there are GB10963 and other signs.

4, try to choose the air switch produced by the regular manufacturer, observe the work, shake whether there is sound, and pay attention to whether there is a pseudo-flag and the appearance of the font distinction.

5, pay attention to the material color distinction, the handle color is different, the handle feels the thrust elasticity is good.

6. The coil is electromagnetically induced. If the short circuit and the overload induction coil pull the trip unit to make it clutch, the number of turns of the copper coil inside the air switch is as good as possible.
