The ALZ21F48W is a power relay from the ALZ21 series, specifically designed for applications that require greater than 2 amps of current in a single load. It has an incredible load-bearing capacity of 100A at 250VAC, making it ideal for use in various industries such as automotive, industrial, and medical applications. The ALZ21F48W is designed with different features that help it to perform better in different environments, including an A-rated, highly-reliable isolation contact structure and gold-plated contacts for superb heat resistance.

The ALZ21F48W utilizes a bimetallic strip switch mechanism to sense an abnormal temperature. This switching mechanism is designed such that when temperature increases, the strip bends and causes a gap in the contact, which in turn disrupts the circuit to prevent a surge or electrical fire. By cutting off the power, it protects the connected components from the harmful effects of excessive current. Therefore, the ALZ21F48W is an excellent choice for safety applications and environments where equipment could run the risk of overloading.

The ALZ21F48W is designed to be compatible with most industry-standard interface connectors. It has a 100x90-mm footprint and is compatible with any kind of mounting, making it easy to integrate with existing systems. The ALZ21F48w also features a wide operating temperature range of -40°C to +105°C and an impressive lifetime of 1 million operations, making it durable and reliable for many years.

The ALZ21F48w works on the principle of electromechanical contact switch. The relay has an input rail connected to the electrical source and an output rail connected to the load. When a current is sent through the input rail, the relay switch is activated. This activates the electromagnet which then pulls in the metal armature to create contact between the input and the output rail, thus completing the circuit. The relay can also be deactivated when the current is removed from the input rail. The ALZ21F48w offers a contact rating of 15A 250V.

With its remarkable load bearing capacity, superior contact structure, compatibility with a variety of standard connectors, and an impressive operating temperature range, the ALZ21F48w is designed to provide reliable performance in any application. Whether it’s in an automotive, industrial, or medical application, this powerful relay has the features to handle the job.
