Circuit breakers are indispensable components used in almost every type of electrical system. The CMLB1-1REC4-52-125.-1-91-T circuit breaker is a specific type of electrical device, which is designed for current and temperature control in alternating current (AC) circuits. This article will analyse the application field and working principle of this type of circuit breaker, showing its importance in the industry.

The CMLB1-1REC4-52-125.-1-91-T circuit breaker is an example of the thermal magnetic circuit breaker, using both heat and magnetism to control the electrical currents. Compared to other types of electrical breakers, such as the electronic circuit breaker, the thermal magnetic circuit breakers offer better performance in terms of their ability to make and break the load current without generating very high transients. In addition, they can be used in a wide range of applications, such as industrial, residential, marine, and commercial.

The thermal magnetic circuit breaker is composed of a main device and an auxiliary device, which are connected by lead wires. The main device consists of bimetallic strip and a magnetic strip, while the auxiliary device contains a coil and other terminals. Together, they form the heart of the circuit breaker.

The working principle of the CMLB1-1REC4-52-125.-1-91-T circuit breaker is based on the heat generated by the bimetallic strip during the electrical current and the magnetic field created by the magnetic strip. When no current runs through the circuit, the bimetallic strip is in a relaxed state, which keeps the switch in the off position. When the current flows through the circuit, the heated bimetallic strip will bend, creating a push on the lever of the switch. This push in turn opens the arms of the switch, and the circuit is broken. The amount of heat generated by the bimetallic strip is dependent on the amount of current flowing through, so the CMLB1-1REC4-52-125.-1-91-T circuit breaker can offer protection against thermal overloads, as it will break the circuit before the current reaches dangerous levels.

The magnetic strip, on the other hand, helps to prevent the current from restarting automatically and even in a more rapid manner. It does this by creating a magnetic field which holds the contacts of the switch together, even when the bimetallic strip has cooled down. As a result, it is possible to have the switch close and open quickly without affecting the current levels.

In conclusion, the CMLB1-1REC4-52-125.-1-91-T is a type of electrical device which offers excellent safety and temperature control in AC circuits. It uses a combination of heat generated by a bimetallic strip and magnetism from a magnetic strip to work effectively. This product is suitable for a variety of applications, such as industrial, residential, marine, and commercial. Its working principle ensures that it can offer improved safety and rapid opening/closing of the switch, thus providing reliable protection for the circuits.
