Application
The ATS LKB and LKF series are designed for switching one source of supply to another without going through a neutral (off) position. It offers economical and reliable solutions for smaller power supply system, either as an emergency supply, standby power supply or alternative sources. It is also suitable to be used in commercial buildings or industrial plants where reliability of power supply is an important requirement.

Mechanism
Both series are designed to have high interrupting capacity with double throw construction, which is mechanically held, electrically operated. It works on solenoid basic to activate the switch and relay, fully auto or manual operated, with this, there will be no maintenance needed and it allow more reliable and faster switching operation as compared to those using complicated motor and gear. The source of supply to the control circuit can be AC or DC and the switch position indicating the contacts are provided too.

Material
Simple operation and compact in size. All contacts & bus bars are of extra size copper with very low resistance level over the contact point, which is able to provide quicker depreciation of heat. The movable arm and main contacts are housing in an arching chamber, it will enable the --- to absorb heat and pass through the arching chamber.

International Standards
The ATS LKB & LKF series conform and meet the requirement of the international of IEC 60947 - 6 - 1
