Power Relays, Over 2 Amps: LY4-AC240 Application Field and Working Principle

LY4-AC240 is a type of power relay among the high power relay series of over 2 Amps, which can be used in low pressure lighting switch, high pressure motor, electric heater, oven, water heater and other household electric and electric heating appliances.

The LY4-AC240 has advantages of AC contact capacity, large contact capacity, high breakdown voltage, small volume and compact structure. It is featured by hermeticity, long service life, no spark and no arc.

The applicable contact load of LY4-AC240 is :AC500V/2A, AC250V/10A, and AC125V/16A.The temperature rise of the bracket is small, and the temperature rise of the contact is only about 10 degrees Celsius.

The working principle of LY4-AC240 is pretty simple. When the coil is energized, the iron core is pulled by electromagnetic force, and the contactor is opened or closed. The contact closure is connected with an elastic spring, which gives the switch a certain spring action. When the coil is de-energized, the elastic spring of the contact returns the movable contact to the starting position and the contactor is closed. Since the contact is in direct contact with the coil, the contact load and the contact temperature are relatively small.

The LY4-AC240 is very suitable for energy-saving environment in power applications. Its small size, high power, high operating frequency and low temperature rise make it ideal for applications that need quick, reliable switching or attractive power savings.

To summarize, the LY4-AC240 has a great application field and working principle. It is a reliable and economical type of power relay and is mainly used in low pressure lighting switch, high pressure motor, electric heater, oven, water heater and other household electric and electric heating appliances, electrical equipment, and other occasions. Its features , such as hermeticity, long service life, no spark and no arc, make it a popular choice for these kinds of applications.
