Circuit breakers are finds of electrical safety devices that provide protection against overcurrent and short-circuit conditions. CB187F-150 is a type of circuit breaker that is designed for use in low voltage electrical systems. It is mainly used to protect personnel, equipment and the wires of the power network from damage in case of an overload or short-circuit.

CB187F-150 circuit breaker is suitable for low-voltage electrical systems such as residential, commercial, industrial and switchboard applications. The main application areas of the CB187F-150 circuit breaker are the protection of household appliances, garage circuits, electric motors and public fields, earth leakage protection, arc-resistant protective device and other places that require effective and reliable protection.

The working principle of CB187F-150 circuit breaker is that when the line current exceeds the current-limiting value, the bulging ring within the circuit breaker moves, depresses and deforms the contact spring. This movement causes an increase in contact resistance, leading to the loss of electrical contact, leading to a "break" in the circuit, thus protecting the power network from current overloads or short circuits.

The main components of CB187F-150 circuit breaker are the body, contacts, insulating connection parts, and air gap. The housing of the CB187F-150 circuit breaker is made of metal or plastic and contains a bimetallic element, contact spring and other metal parts. The contact is the main component of the CB187F-150 circuit breaker, which is connected with the bimetallic element and is pushed to the contact point. When the current through the contacts is excessive, the bimetallic element heats up and causes the contacts to separate, thereby breaking the circuit.

The CB187F-150 circuit breaker has a good performance and is widely used in low voltage electrical systems, providing a safe and reliable power supply protection. It is also very easy to install and maintain. In addition, it has multiple features such as overvoltage protection, overcurrent protection, short circuit protection and is resistant to shock, withstanding large short-circuit current. Therefore, it is a reliable and cost-effective solution for protecting low-voltage electrical systems and equipment.
