Voltmeter accuracy and specifications: 1.5 class, 30V, 50V, 75V, 100V, 120V, 150V, 200V , 250V, 300V, 400V, 450V, 600V, 450V-450KV Note: It can be connected to an external voltage transformer with a secondary voltage of 100V. Features: 1.Explosion-proof button box is suitable for AC 50Hz, 220/380V, DC voltage to 220V line, remote centralized control of the start and stop of multiple motors. 2. It is composed of increased safety shell, flameproof components (indicator light, ammeter, voltmeter, potentiometer, button, universal switch) and wiring terminals. 3. The shell is made of aluminum alloy casting (high-voltage electrostatic spraying after shot blasting) or glass fiber reinforced unsaturated polyester resin molding. It has excellent properties such as beautiful shell, corrosion resistance, antistatic impact resistance and good thermal stability. 4. The built-in components are directly clamped on the standard guide rails. The protrusions on the components and the grooves on the guide rails ensure that the built-in components are installed in a certain position. The minimum center distance between the components and the components is 42mm. 5, can be steel pipe or cable wiring. 6. There are many variations of this product, which can be made according to the electrical schematic diagram provided by the user. 7. There are more than 30 functions of the universal switch, which can be selected by users as required. 8. It can be equipped with a rain cover according to user requirements. 9. The specially designed sealing structure can effectively improve the product protection level while meeting the explosion-proof performance. 10. Comply with GB3836-2000, IEC60079 standard requirements. Note: Due to the ever-changing arrangement of components in the control box, the arrangement of components with body should be designed and manufactured by our company according to the electrical schematic diagram provided by the user when ordering, jointly study the schematic diagram of the arrangement of components or put forward requirements. Scope of application: 1. Zone 1 and Zone 2 hazardous locations; 2. "Exde Ⅱ BT6" products are suitable for IIA, IIB explosive gas environments; 3. "Exed II CT6" products are suitable for IIA, IIB, IIC explosive gas environments; 4 ."Exed Ⅱ CT6" product is also suitable for combustible dust places; 5.
