|
1. 适用于交流50Hz、220/380V，直流电压至220V的线路中控制接触器、继电器、照明及其它电气设备的接通和分断之用；
2. 控制箱由外壳、隔爆型元件（信号灯、电流表、按钮、开关）及接线端子等组成；
3. 外壳采用玻璃纤维增强不饱和聚酯树脂或铸铝合金制成，具有外形美观、耐腐蚀、抗静电、耐冲击及热稳定性好等性能；
4. 控制箱元件布置千变万化，具体元件排列要根据用户要求，并提供原理图，共同研究元件排列示意图或提出要求由我公司进行
设计和制造。
1. Apply to control the on-off operation of contact, relay, ighting and other electric equipment in the circuit of AC 50Hz, 220/380V, DC
voltage up to 220V;
2. The controlling box is composed of secure shell, flame-proof elements (signal indicator, ammeter, button, switch) terminals, etc;
3. The pressing shell made of fiberous glass, reinforced unsatur ated polyster corrosion-proof, static electrity resistance, impactresistance and
reliable-heating;
4. The detailed elements arrangement should depend on the schematic diagram of uses for jointly working out the elements-arrangement's
sketch or requiring our company to help you de sign and making, due to the thousands of elements-arrangementin controlling box.
