With the increase in our household appliances, the style and type of switches are increasing. In order to make it easier for everyone to use the switch socket, the universal transfer switch allows us to better use a variety of electrical appliances. However, many people do not know the model of the universal transfer switch. Next, let's take a look at the universal transfer switch model.
What is the universal transfer switch?
Universal conversion switch is mainly suitable for AC 50Hz, rated working voltage 380V and below, DC voltage 220V and below, rated current to 160A electrical circuit, universal conversion is mainly used for conversion of various control lines, voltmeter, ammeter Commutation measurement control, conversion of power distribution lines, and remote control. The universal transfer switch can also be used to directly control the start, speed and commutation of small capacity motors.
Universal transfer switch model
The existing domestic LW2, LW4, LW5, LW6, LW8, LW12, LW15, LW16, LW26, LW30, LW39, CA10, HZ5, HZ10, HZ12 and other types of switches and universal conversion switches on imported equipment are widely used. The universal transfer switch has a padlock type switch and a dark lock type switch (63A and below), which can be used as a power cut-off switch for important equipment. Prevent misuse and control the operation of unauthorized personnel. The most common universal transfer switches are the LW5, LW6 and LW12 series.
Universal transfer switch structure
The universal transfer switch is a multi-loop control device that is assembled by stacking a plurality of sets of contact components of the same structure. It consists of operating mechanism, positioning device, contact, contact system, shaft, handle and other components. The contact is in the insulating base and is a double-break contact bridge structure. The movable contact is designed to be automatically adjusted to ensure synchronization during on-off, and the static contact is mounted in the contact seat. It is operated by cam and bracket to control the closing and opening of the contact.
