Power Relays, Over 2 Amps

The MY4I4 AC12 is a powerful industrial grade device designed to provide reliable switching of electrical circuits. It is typically used in medium to heavy duty applications, such as electric motors, lighting systems, and power supplies. The MY4I4 AC12 is highly reliable, and is rated up to 12 Amps.

Design and Construction

The MY4I4 AC12 relay is made up of a base unit, two contact assemblies, and a terminal block. The base unit consists of a plastic housing, which houses the contact assemblies. The contact assembly consists of a set of silver-plated beryllium copper contacts, which are held in place with a ceramic insulator. The base also contains two terminal blocks, which are used to connect the contacts to a power supply.

Application Field and Working Principle

The MY4I4 AC12 is designed for use in moderate to heavy-duty applications where high switching reliability and current capabilities are necessary. It is typically used in electric motors, lighting systems, power supplies, and other applications where a reliable, long-lasting switch is required. The MY4I4 AC12 operates on the principle of magnetic latching. When power is applied to the contact assembly, a magnetic field is generated which causes the contacts to close. When the power is removed, the contacts remain closed due to the magnetic field. This makes the MY4I4 AC12 ideal for applications where the switch must remain in the closed position even if power is lost. The MY4I4 AC12 is designed for use with alternating current (AC) sources up to 12 Amps. The contacts are rated for up to 10 Amps of continuous current and 12 Amps of non-continuous current. The relay is also designed to withstand temperatures up to 85°C (185°F).

Conclusion

The MY4I4 AC12 is a highly reliable and durable industrial grade relay. It is designed for use in applications such as electric motors, lighting systems, and power supplies. The relay operates on the principle of magnetic latching, and is rated up to 12 Amps of alternating current. The MY4I4 AC12 is an ideal solution for applications where reliable switching and long-term use are important.
