ALZ21F12

Power Relays, Over 2 Amps

The ALZ21F12 Power Relay is designed to offer reliable performance and efficient operation for applications that require more than 2 Amps. It features a double electrical distribution that ensures reliable electrical contact over extended periods of time, and is designed to provide protection against high voltage fluctuations in the event of power outages. In addition, its robust construction allows for operation in harsh and extreme environments.

The ALZ21F12 Power Relay’s primary purpose is to switch a large amount of electrical current between two or more circuits for a variety of applications. It allows for the remote control of electrical devices such as motors, transformers, heaters, lighting systems, and HVAC systems. In addition, it can also be used in control applications such as load shedding, environmental management, and safety systems.

Rugged construction and several metal parts extend the relay’s operational life and reduce electrical contact failure in severe conditions. The relay’s robust construction also helps increase its switching capacity and ensures safe operation in harsh environments due to its ability to withstand heat, dust, and moisture. The ALZ21F12 is also UL and CSA approved, making it certified safe for use in commercial and industrial applications.

The ALZ21F12 Power Relay functions by using electricity to create a magnetic field, which activates the relay’s switch arms to open and close contacts. When an electrical signal is sent to the relay, its switch arms interact with the metal components to will either open or close the contacts. The relay will remain in the state (open or closed) until it receives an electrical signal that either turns the relay ON or OFF.

The ALZ21F12 Power Relay is suitable for a variety of applications, including industrial control systems, motor control systems, and safety systems. As a reliable and cost-effective solution, this relay offers superior performance for applications that require high currents and voltages. Its robust construction ensures reliable performance and long-term reliability, even in harsh environments.
