Circuit breakers are used in an electrical circuit to protect it from power overloads, short circuits and ground faults. The LELB1-1RS4-36944-20-V is a type of circuit breaker that is used in industrial applications. It is designed to provide over-current protection for electrical devices in industrial, commercial and residential applications.

The LELB1-1RS4-36944-20-V is a single-pole, thermal-magnetic circuit breaker with both overload and short-circuit protection. It has an operating voltage of 120/277V AC, rated frequency of 50/60Hz and an operating temperature of 32 - 140°F (0 - 60°C). It is also UL 1077 CSA C22.2 recognized, and carries a UL 489 listing.

The working principle behind the LELB1-1RS4-36944-20-V is relatively simple. It has a thermal-magnetic design which means it functions both on heat and magnetic forces. The heat is generated inside the breaker due to the electrical current flowing through it and this current creates a magnetic field. This field causes the breaker to engage its internal trip mechanism, which ultimately triggers the circuit to disconnect.

Additionally, the LELB1-1RS4-36944-20-V has a manual reset feature which allows the user to manually reset the breaker after it has tripped. The reset can be done simply by pushing the reset button on the front of the breaker. This is important for applications that require constant power, as it allows for a quick and easy reset in case of a fault or power overload.

The LELB1-1RS4-36944-20-V is a great choice for applications that require reliable over-current protection. It has a long life cycle and is designed to be rugged and reliable. This type of circuit breaker is suitable for a variety of applications, including industrial, commercial and residential, where the electrical current needs to be monitored and controlled.

In conclusion, the LELB1-1RS4-36944-20-V is a reliable and durable circuit breaker designed to provide over-current protection for a variety of electrical applications. It operates on a thermal-magnetic design and has a manual reset feature for quick and easy resetting when needed. It is a great choice for industrial, commercial and residential applications and provides a long life cycle and reliable protection from electrical faults and power overloads.
