[Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office to recommend the star product - Explosion-proof distribution box distribution box] improvement program: a protection circuit prevents the use of an external power distribution box circuit failure. Choose smaller smart lack of protection, such as the choice of DA88CM-II phase motor protection module (Shanghai product) installed in low voltage power distribution box in order to prevent burn out the motor running phase. 2 selection of energy-efficient AC contactor (similar CJ20SI type) products, and pay attention to AC contactor coil voltage remaining for the selected current device is connected to the corresponding terminals, pay attention to correct load matching. When selecting AC contactor should be used in the insulation rating of A-level and above products, must ensure that its rated current of the main circuit contacts should be greater than or equal to the load current is controlled by the line. Contactor solenoid rated voltage of 380V or 220 V, coil to allow 80% of rated voltage - use within the 105% range. Proof of the benefits of the current distribution box distribution box type vary, usually used in home explosion of household distribution box distribution box someone good quality, damp places with stainless steel distribution box, flammable and explosive proof necessary distribution box, for aesthetic and distribution box made of glass, dark place in the night with the lighting distribution box explosion distribution box, as well as an upgraded version of the explosion-proof lighting distribution box. Next, we take the necessary proof of flammable and explosive power distribution box to explain. What distribution box is it? Distribution box is used to allocate the appropriate power to the switching operation of the circuit can be simpler, filled the circuit, the circuit can be directly observed in the conduction. So for the distribution box, the explosion distribution box by definition is to prevent an explosion of the distribution box. To be safe to have a proof distribution box is necessary, especially in some of the more dangerous places How much proof distribution box, such as: oil and chemical or military, etc. These high explosive risk areas, for safety reasons installed distribution box should be installed even Ex-distribution box. Original proof distribution box which now are basically the type of explosion-proof characteristics of multi-distribution box is specially treated, tank shells are also generally increased safety can be said to be foolproof distribution box. Although what the occasion for what kind of product, but proof distribution box can be applied in any place, even if not explosive hazardous locations can be used indoor and outdoor are possible. Some of the streets in order to secure the distribution box filled with masses of people are also proof distribution box. So in recent years has been to develop proof distribution box on the rise is because of these reasons. Explosion distribution box where to sell | good Koretoyo proof quality | Tanggu explosion distribution box from Zhejiang Koretoyo explosion-proof electrical Co., Ltd. Tianjin offices. Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (www.tjfangbao.com) is Tianjin, explosion-proof lighting leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Koretoyo explosion in leadership with the staff warmly welcome all inquiries to discuss, but to create a better future abundance of proof.
