Protection type (ie enclosed) switchgear, in addition to the mounting surface means, all other sides are closed up in a low-voltage switchgear. This cabinet switches, protection and monitoring control and other electrical components factory explosion-proof electric control boxes are installed in a steel or enclosure made of insulating material, can be installed against a wall or away from the wall. Each cabinet can not add between underground explosion-proof electrical circuit isolation control box can also be used a grounded metal plate or insulation board isolation. Typically the door and the main switch operating a mechanical interlock. Another type of protection switchgear units (ie, the console) explosion-proof electrical control box manufacturer, equipped with control, measurement, signal and other electrical panel. When the protective switchgear is mainly used for power distribution unit site selection process exchanges and contacts, should be used in the insulation rating of A-level and above products, must ensure that its main circuit contacts rated current should be greater than or equal to the control line load current. Contactor solenoid rated voltage of 380V or 220 V2. Optional similar LJM (J) series energy-saving type, and is the low sensitivity of delay protection. Way protection device to comply with national GB13955-2005 "residual current operated protective devices to install and run" standard proof electrical control box price | 20 years Koretoyo Explosion | Jinzhong proof electrical control box by Zhejiang Electric Co., Ltd.
