Circuit breakers are essential components of all electrical systems and offer overload and short circuit protection. The R21-4-15.0A-B161CV-V is an example of a circuit breaker and offers a range of features and benefits. Below, we will explore its application field and working principle in more detail.

When it comes to its applications, the R21-4-15.0A-B161CV-V is suitable for a wide range of environments and systems. It can be used in both commercial and residential settings, and is suitable for use in low-voltage electrical systems. It is also ideal for use in environments where 1-phase alternating current is used, up to a frequency of 400 Hz. Moreover, the R21-4-15.0A-B161CV-V is suitable for use in extreme temperatures, offering reliable and efficient protection up to 125℃.

The R21-4-15.0A-B161CV-V circuit breaker is designed to be paired with a range of devices, including transformers, contactors and other circuit breakers, ensuring reliable protection even when there are multiple devices in a system. It is also compatible with a range of electronic devices, making it ideal for a wide range of applications.

The R21-4-15.0A-B161CV-V circuit breaker is a thermal and magnetic circuit breaker, which uses a combination of both designs to provide reliable overcurrent protection. The thermal design contains bimetallic elements that are designed to bend when exposed to high temperature. This bending then causes the contacts to open, preventing any current from travelling through the system. The magnetic design also works in order to prevent any overcurrents, by introducing a small magnet into the circuit breaker. This small magnet is then activated by any abnormal current, which causes the contacts to open and shut off the supply.

In addition to its overcurrent protection, the R21-4-15.0A-B161CV-V circuit breaker also offers a range of other features. These include over- and undervoltage protection, thermal limiting and short-circuit protection. These features help to ensure that the electrical system is protected and that any sudden surge or drop in power does not cause any system malfunctions.

The R21-4-15.0A-B161CV-V circuit breaker is an example of a reliable and efficient electrical device, offering a wide range of features and benefits. With its combination of thermal and magnetic protection, it offers reliable overcurrent protection and short-circuit protection, making it suitable for use in a range of environments. Additionally, it is suitable for use with a range of other devices, ensuring that the circuit breaker can be integrated easily into any existing system.
