CB187F-80 Circuit Protection

Circuit breakers are essential for modern electrical systems and products. A circuit breaker is a device that interrupts the flow of electricity, and it is often used in cases where the electrical system experiences overload. CB187F-80 circuit breakers are especially designed for industrial usage and have a number of unique features.

This circuit breaker type is mainly applied for AC 50/60 Hz up to 440 volts. It has three-phase four-pole breakers plus neutral, all in same body. It is designed to the DIN standard, and the contact material of its poles is silver alloy with zinc chromate finish. The CB187F-80 can be used for control applications or constructions in machinery, and it can also be used for air conditioning, solar, elevators, pumps, defense, communications, power plants, etc.

The working principle of CB187F-80 circuit breakers is as follows. When current passes through the breaker, a medium-sized iron core of the breaker is attracted and the breaker contacts shift apart, opening the circuit quickly and efficiently. When a current overload or short circuit occurs, a large current will flow, causing the amount of iron to wear away very quickly. This will cause the breaker contacts to be separated very quickly, thus opening the circuit. The heat generated by the current is also absorbed by the connected copper pieces and converted into mechanical energy. The mechanical energy then causes a plunger inside the breaker to activate, thereby activating the trip mechanism of the breaker.

The unique construction and design of the CB187F-80 make it one of the safest and most dependable circuit breakers in the world. It has a number of features designed to protect the circuit from overloading, overload current, short circuit current, and mechanical destruction. The trip mechanism is designed to respond to overloads quickly, and the copper buses, along with the heavy-duty air ducts, are designed to help dissipate the heat generated by high current. This helps to reduce the risk of thermal destruction. In addition, the CB187F-80 is equipped with multiple safety features such as phase failure detection, short circuit protection, overheat protection, and over current protection.

In conclusion, the CB187F-80 is an ideal circuit breaker for industrial settings, due to its robust construction, excellent protection, and wide application field. It has a number of features designed to provide safe and reliable power protection for applications in a variety of situations, and its working principle is quick and reliable.
