用途 Application LJW26系列轉(zhuǎn)換幵關(guān)主要用于交流50HZ，額定工作電壓690V及以下，直流電壓240V及以下、約定電流至160A的電氣線路中，供手動(dòng)不頻繁接通或分?jǐn)嚯娐纷骺刂坪娃D(zhuǎn)換之用，也可直接控制小容量交流電動(dòng)機(jī)和作主令控制及電路測(cè)量之用，產(chǎn)品用途廣泛，可作為電路控制開關(guān)、測(cè)試設(shè)備開關(guān)、電動(dòng)機(jī)控制開關(guān)、主令控制開關(guān)及電焊機(jī)開關(guān)等。 LJW26系列開關(guān)具有體積小、功能多、機(jī)構(gòu)緊湊、選材講究、絕緣好、轉(zhuǎn)換操作靈活、安全可靠以及外觀造型新穎等特點(diǎn)，其中LJW26-20/04GS或稱LJH13型護(hù)指式電源切斷開關(guān)具有護(hù)指功能簡(jiǎn)稱為護(hù)指開關(guān)。 LJW26 series changeover switch is used in the circuits of AC 50Hz, rated voltage up to 690V, DC voltage up to 240V, rated current up to 100A, to not frequently switch on/off circuit, transfer and control circuits, also it can directly control small capacity motor or be used for master control or electric meters. The switch is used widely in circuit control, test equipment,switch for motor, master control, welding machine and etc. Advantages: small size, multifunction, compact structure, high quality material, good insulation，agile operation，reliability, safety, good appearance. LJW26-20/04GS or LJH13 type armor power switch is off to protect functions for protection as to switch. |
