Circuit Breakers

CB212-25 Application Field and Working Principle

Circuit breakers are an important part of electrical systems that act as safety devices to protect them and their components from electrical overloads. They provide a simple and effective way to prevent potentially hazardous or dangerous situations from occurring. The CB212-25 circuit breaker is a general-purpose device used to protect electrical wiring from being overloaded and short-circuited. This particular breaker has an open- and closed-circuit indicator to indicate whether the current flow is continuous or not.The CB212-25 is most commonly used to protect residential and business buildings from overloading circuits. It is also used to protect motors, heating systems, and appliance circuits in residential, industrial, and commercial settings. It is not recommended for use in high-voltage applications.The CB212-25 is a dynamically tested, two-pole circuit breaker designed in accordance with IEC/EN60947-2. It is a 440 A-rated breaker with a 25 ampere rating that utilizes a no-trip/trip mechanism. This means that the circuit breaker will not trip unless the current draw exceeds its rating. In other words, if the circuit’s current demand suddenly increases, the CB212-25 will trip to prevent overloads and consequent damage. The CB212-25 can be connected to a line load and neutral wire up to a maximum of 440A. This circuit breaker is suitable for overcurrent protection of multiple types of installation, including lighting circuits, industrial machines, motors, fans, and household appliances. Its overload protective device utilizes high dielectric and mechanical strength material with thermal-magnetic, manual resetting properties, allowing it to provide the highest degree of safety and protection. Additionally, it has the ability to trip at temperatures up to 60 degrees Celsius.The CB212-25 has a tripping current range of 8A to 25A (including minimum and maximum currents). This range can also be adjusted by means of turning the adjusting bar and adjusting screws located inside the breaker. The CB212-25 is designed to trip at a nominal time of 30-60 milliseconds.The CB212-25 has a manual-trip system with a test button that allows it to be tested periodically for safety. The test button is conveniently located at the front of the breaker for easy access. In addition, the CB212-25 can be connected to remote alarm systems. This feature is especially beneficial in larger industrial settings, where it is important to monitor the condition of the breaker.The CB212-25 is a two-pole breaker and is available in both surface- and flush-mounting versions. It has a UL rating of UL1077, meaning it meets the relevant UL standards. This CB212-25 has a polycarbonate case and is capable of withstanding temperatures up to 130 degrees Celsius.In conclusion, the CB212-25 is a reliable and safe circuit breaker designed to protect residential, industrial, and commercial settings from overloading circuits. It is easy to use and has an open/closed circuit indicator to quickly identify whether the circuit is open or closed. Additionally, its manual-trip system and adjustable tripping current range make it a reliable, versatile, and safe choice for most electrical applications.
