Circuit breakers are an integral part of power engineering, providing overcurrent protection to the electrical system. The UPL5-31261-1 model circuit breaker is an example of a Thermal Magnetic Circuit Breaker (TMCB). It is designed to be used in residential, commercial, or industrial settings and is used primarily for overload protection.

The UPL5-31261-1 circuit breaker works on the principle of “Thermal Magnetic Action," meaning that it uses both thermal and magnetic forces. The thermal element is a bimetallic strip that is designed to bend when heated by an electrical current. When enough current is passed through, it will bend and eventually disconnect the circuit. The magnetic element is composed of an electromagnet field which is generated when a large electrical current flows through the circuit. This magnet pulls the tripping bar, which trips the breaker, breaking the circuit.

The UPL5-31261-1 is a highly reliable circuit breaker, offering a wide range of features. It has adjustable thresholds allowing for a custom trip setting, a thermal release system that ensures the device will trip even if there is a system fault, a removable base plate that allows for easier servicing, and it is also UL listed for safety.

The UPL5-31261-1 model circuit breaker is a great choice for residential, commercial, or industrial applications where overcurrent protection is required. Its adjustable thermal/magnetic action provides adequate protection while its easy installation and UL listing make it an excellent choice for industrial and commercial applications.
