4435.0021 Circuit Protection

Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. This helps to limit the amount of damage that can occur to an electrical circuit due to a short circuit, or overload, thus preventing a fire and possible injury.

The 4435.0021 circuit breaker is particularly useful in applications that require reliable connection of control systems and automated actuators. The 4435.0021 offers reliable switching and current limitations. The main features of the 4435.0021 circuit breaker include its ability to close on a minimal load and to maintain a high level of performance in environments with high electromagnetic interference. The device is also overload and surge protected, with a fusing time of 8ms.

4435.0021 Application Field

The 4435.0021 circuit breaker is ideal for applications in industrial automation and control systems. It can be used in areas such as:

• Lighting and HVAC (heating, ventilation, and air conditioning) control
• Security systems control/monitoring
• Automatic switching of circuit protection
• Load shedding or load balancing applications
• Professional and domestic power line (PLC) protection

4435.0021 Working Principle

The 4435.0021 circuit breaker is a current operated device, meaning it senses the current flowing through the device and then opens or closes the circuit, dependent on the current flowing. It has an over-current protection element, which is designed to disconnect the circuit from the mains supply in the event of an overload. It is also surge and overload protected, meaning it can be used in areas with high electromagnetic interference. In general, the 4435.0021 is designed to provide a consistent switching performance in a wide variety of applications.

The 4435.0021 circuit breaker is designed to be easy to install and maintain. It has a built-in thermal protection feature that will trip if the temperature inside the circuit breaker exceeds the maximum allowed. The device also has a built-in LED indicator that will light up when it is in use, providing a quick indication to maintenance personnel that the system is functioning correctly. The circuit breaker is also tested to meet UL and CSA standards.

The 4435.0021 is an advanced, versatile, and reliable circuit breaker designed to meet the needs of a wide variety of applications. Its robust design offers Plug-&-Play operation for quick and easy installation, making it ideal for applications in industrial automation, security systems, and load balancing applications.
