purpose

The KO5-M (QS) series reversing switch is a patented new product (patent number: 973 12941.7) that replaces the old QS series switch. It is the most innovative, beautiful, small in size, flexible in operation, and has a long service life among similar products. Especially, it has excellent dustproof and waterproof performance, so it can be widely used in various environmental conditions.
This series of waterproof reversing switches is suitable for circuits with AC 50HZ, rated voltage up to 380V, and maximum capacity of 5.5KW. It is used to directly turn on and off a single asynchronous motor, enabling it to start, run, stop, and reverse.

Main specifications and technical parameters:

Model	Agreed heating current A	Agreed working current A	Rated working power KW
Model	Agreed heating current A	Agreed working current A	Ue380V	Ue220
KO5-M-16	sixteen	seven	three	one point seven

Application of KO3 series reversing switch

1. This series of switches is suitable for use in AC 50HZ three-phase three wire system conversion phase sequence wiring, such as controlling the forward and reverse rotation of motors. The technical performance indicators of the switches comply with GB14048.5-93 standard.
2. The maximum capacity of the motor controlled by this series of switches is shown in the table below

Specification Model	220V	380V
KO3-15	1.7KW	3KW
KO3-30	3.4KW	5.5KW

3. This series of switches should be installed inside circuit control switches and fuses, and should not be used for single power control. They should also not be installed in excessively humid or corrosive gas environments.
4. This series of switches should be used below the rated capacity, but should not be used for sudden braking.
5. When using this series of switches, the contact surface and rotating mechanism of the contacts should be checked regularly. If there is any burning or inflexibility, the power should be disconnected and the switch should be repaired before use.
6. This series of switches should be properly grounded during installation.
7. The installation dimensions of this series of switches are shown in the following chart

Model	A±0.50	B±0.50	Ø±0.50
KO3-15	sixty	fifty-two	six point five
KO3-30	ninety-five	seventy-five	seven
