Product Description

Introducing the LW30 series load disconnect switch by Lixin, setting a new standard in modern electrical control solutions.Our LW30 series switch has complete specification,we have 20A,25A,32A,40A,63A,80A and 100A current grades.LW30 has many different features,such as small volume,compact structure,high quality materials,better insulation,finger protection,safety and reliable.You can add different contact blocks to the 3-pole standard block without removing the switch.The insulation distance of LW30 series switches is greater than that of other switches of the same type,it has fast disconnect speed and suit for DC switch.

There are some installation precautions you need to conform when you install the switch.Before installing the switch,you must ensure that the power is disconnected to avoid electric shock.The environment must be dry and draughty,can not be high temperature and damp.You have to use fit screws to secure the switch.You need to connect cables according to the circuit diagram to ensure that power cables and load cables are correctly connected to avoid poor contact.

Following the above precautions,you can ensure the safe and reliable operation of the switch.If there is an anomaly, it should be replaced or repaired in time to ensure the normal operation and service life of the product.
