Long Switching Service Life
Aug 28, 2017

Switch switch supplier is a multiple-file, control multiple circuit of the main order of the main electrical appliances suppliers. When the handle is rotated, the cam inside the switch is driven, Change Over Switch so that the contact points are closed or disconnected in the specified order. Switch switching switch suppliers are mainly used for various control circuit conversion, voltmeter voltage meter supplier, Change Over Switch ammeter commutation measurement control, distribution device line conversion and remote control.

The switching switch is a multiple loop control apparatus, which is made up of the same structure of the contact component. It consists of three parts: operation mechanism, positioning device and contact point. The contact point is a double breakpoint bridge structure, Change Over Switch and the dynamic contact point is designed to automatically adjust to ensure the synchronization of the same short time. The static contact point is in the contact seat. When the handle is rotated to a different gear, the hinge rotates with the cam so that the contact is closed or disconnected in the specified order.

Switching switch has the advantages of long life, Change Over Switch reliable use and simple structure.

Switching switches are mainly used in the conversion of various control lines, voltage meter, Change Over Switch ammeter commutation measurement control, distribution device line conversion and remote control. The universal switching switch can also be used to directly control the starting, speed and commutation of small-capacity motors.

Switch switch can be used for AC 50Hz, Change Over Switch voltage 500V and DC voltage 440V circuit, for the electrical control line conversion and voltage 380v5.5KW and the following three-phase squirrel cage Induction Motor Direct control of the use. The product complies with GB14048.5 standard.

Structural characteristics

By use, there are main control switches and direct control 5.5KW three-phase squirrel cage asynchronous motor with two kinds.

According to the number of contact systems, there are $number sections, a total of 16.

The combination of operation and actuator position,

According to the mode of operation: There are two types of self-complex with positioning type

According to the shape of the actuator: the ball-type pinch hand and knob type two.

According to work system: there is intermittent cycle work (operating frequency 300 times/hour) and eight hours working system.

According to the form of protection: there are two types of open type and protection.

Main technical Data

The open switching switch is contracted with a heating current of 16A. The protective type only provides reversible switching switch LW5-16/5.5N3, which is sealed with a heating current of 16A, Change Over Switch the Enclosure protection rating is: IP40.

The rated insulation voltage of switching switch is: 500V.

Rated operating voltage (UE) and rated operating current (Ie) for switching switches

A. Nominal operating voltage (Ue) and rated operating current (Ie) for switching switches for master control

B. Direct control 5.5KW three-phase cage motor switching switch rated operating voltage of 380V rated operating current is 12A.

C. The two-breakpoint contact groups belonging to the same switching switch are electrically separate, Change Over Switch so each pair of breakpoint contacts can control an independent electrical circuit.

D. Switching switch of electrical life 20x104 more than once,

E. Switching the mechanical life of the switch 100x104 more than once.
