Power Relays, Over 2 Amps

KA-11AY-24 is an industrial power relay which is suitable for electric equipment of AC 50/60 Hz. Its rated operational current ranges from 3A to 10A and its rated operational voltage is 690VAC. It is a high-current relay with good contact stability and long life of contact-welding, which is widely used in circuits of ordinary household appliances, lamps, toys, electromagnetic switches and other fields.

Structure and Features

The KA-11AY-24 relay is composed of a coil, a contact group and a housing. The coil is made of fire-resistant hard-magnetic materials, with simple structure, good insulation, stable performance, reliable operation, and wide range of voltage selection. The contact group is composed of a coil, contact cylinders and springs. The contact cylinders are riveted between the bottom plate and the insulation cushion, and are subject to the action of the springs between the contact poles and the poles, so as to achieve the on/off switching. The housing is made of high temperature resistant plastic, with fast heat dissipation, good flame retardancy and good insulation. The KA-11AY-24 is also equipped with a protective device that can effectively reduce arcing and effectively suppress small noises when switching, making it suitable for manual and automatic control.

Application Field and Working Principle

The KA-11AY-24 is suitable for circuits of household and office appliances, pump and motor control, electronic toys, relays, lights and other fields. It is suitable for AC 50/60 Hz with a rated operational current of 3A-10A and a rated operational voltage of 690VAC. It adopts electromagnetic controlling mechanism, which can be controlled by manually or automatically. When the rated working voltage is applied to the input terminal, it will generate the magnetic field, making the contact points close, and thus enabling the controlling circuit. When the control voltage is removed, the magnetic field disappears, and the contact points open, thus breaking off the controlling circuit. The KA-11AY-24 has good contact stability, high current load capability, and long life of contact welding. This makes it a reliable option for a variety of applications.

Maintenance and Precautions

When installing and using the KA-11AY-24, it is important to be aware of its operating temperature range, voltage range, and current range, and make sure that it is not overloaded beyond these parameters. Moreover, the contact points should be checked regularly to verify their operation. For the product to function correctly, it should be operated in a non-corrosive, non-greasy, non-explosive gas-free environment with temperatures between -10℃ and +50℃.In conclusion, the KA-11AY-24 is an industrial power relay that impresses due to its high current load capability, good contact stability, and long service life. As long as the device is kept within the recommended operating temperatures, voltage, and current ranges, it will be a reliable and powerful tool for various applications.
