Circuit breakers are safety mechanisms that protect electrical and electronic systems from overloads and short circuits. They are widely used in homes, offices, factories and industry, and can be found in many types of systems. The 209-1-1REC4-25986-1 circuit breaker is a single and two pole thermal magnetic circuit breaker with adjustable trip curve. It is designed to protect circuits and equipment from overload, short-circuit and earth leakage.

The 209-1-1REC4-25986-1 circuit breaker consists of two electromagnet coils, a thermal element and an adjustable trip bar. The two electromagnet coils, when energised, act as an electro-magnetic lock, preventing the breaker from being reset until the power is turned off. The thermal element allows for adjustment of the trip curve, allowing the circuit breaker to detect fault currents more quickly and accurately. The adjustable trip bar is used to adjust the contact gap between the two poles, which will trip the breaker when the contact gap is exceeded.

The 209-1-1REC4-25986-1 circuit breaker can be used in a wide range of applications including residential, commercial and industrial. It is specifically designed to protect overload and short circuit currents, and can also be used to detect fault currents in an electrical system. It is suitable for both single and two pole applications, and can be used to protect both fixed and portable electrical systems.

The working principle of the 209-1-1REC4-25986-1 circuit breaker is that when the current exceeds the rated current, the temperature of the thermal element will rise due to the Joule heating effect. If the current is not limited by the thermal element, the contact gap between the two poles will be exceeded, causing the circuit breaker to trip. This is done by the adjustable trip bar, which is adjustable according to the individual needs of the system.

The 209-1-1REC4-25986-1 circuit breaker is widely used in electrical and electronic systems to protect against current overloads and short circuits. It has an adjustable trip bar which allows precise control over the trip point, allowing it to detect fault currents more quickly and accurately. Its thermal element also makes it suitable for applications where the temperature of the system needs to be controlled. The 209-1-1REC4-25986-1 circuit breaker is a reliable and versatile safety device for both residential, commercial and industrial applications.
