用途 Application

       HZ5系列组合开关主要用于交流50HZ,额定工作电压380V及以下，直流电压240V及以下、额定电流至63A的电气线路中，供手动不频繁接通或分断电路作控制和转换之用，也可直接控制小容量交流电动机和作主令控制及电路测量之用，控制电机变速之用。

      HZ5-S带锁扣型开关在原HZ5系列组合开关主体上加装锁扣部分而成。S型锁扣开关主要用于机床电源部分的开关，由于增加了锁扣装置，开关只有两位置。即L: 0-60°。HZ5-20GS挂锁组合开关是HZ5-20A派生产品，主要用作机床中要求能用挂锁的电源切断开关，在断开位置（即“0”或“OFF” ) 和接通位置（即“1”或“ON” )能用挂锁锁住，因而具有安全、专人专机和防止误操作的特点。

HZ5 combination switch is mainly used in the circuits of AC 50Hz, rated voltage 380V and below, DC voltage 240V and below, rated current up to 63A, to manually transfer and control circuit non-frequently, also it can directly control small capacity alternating motor, used as master control and electric measurement.

HZ5 - S take lock switch on the main switch HZ5 series with lock parts. S-type lock switch machine is mainly used for power supply switch, due to the increased lock device switch, only two positions. L: namely 0-60 ° ? HZ5-20GS padlock combination switch is derived products, HZ5 20A - is mainly used in the machine can cut OFF the power required padlock, disconnect the position of switch (namely ?〇** or "OFF" position (namely) and connected to a *1* or *ON*) can lock padlock, safe and special plane and prevent incorrect operation characteristics.
