Circuit Breakers

Circuit breakers are devices used to protect circuits and prevent overloads. The LEL111-2R-34173-1-V is a type of standard circuit breaker with an application field and working principle that is worth understanding.

Application Field

The LEL111-2R-34173-1-V is a 3-pole breaking capacity circuit breaker that is used in electric power distribution systems. It is a cost-effective circuit breaker that has a breaking capacity rating of 63 A and a max rated voltage of 240V. It is UL listed for both indoor and outdoor use and can be used in residential, industrial, and commercial applications. The LEL111-2R-34173-1-V also comes with a range of features, including an adjustable time delay, adjustable energy storage/delay rating, and adjustable current rating.

Working Principle

The working principle of the LEL111-2R-34173-1-V is based on the principle of thermal-magnetic tripping. This type of circuit breaker relies on thermally activated switches that are triggered once the circuit temperature exceeds a predetermined level. This switches on a magnetic latch that trips the circuit breaker, thus breaking the circuit and preventing any further damage. This type of circuit breaker also offers adjustable time delay and adjustable energy storage/delay rating, meaning that the circuit breaker can be set to trip after a certain amount of time or a certain amount of energy is consumed.

The LEL111-2R-34173-1-V also utilizes a number of other safety features that help prevent damage to the circuit. The breaker uses an adjustable current rating so that the trip time can be varied to ensure the correct overload protection. Additionally, the breaker includes a lockout/tagout feature that ensures the breaker cannot be reset until the lockout/tagout procedure has been completed. Finally, the LEL111-2R-34173-1-V also includes an adjustable set of LEDs that indicate the trip level, thus providing a visual warning of potential overload conditions.

Conclusion

The LEL111-2R-34173-1-V is an economical and reliable 3-pole breaking capacity circuit breaker suitable for residential, industrial, and commercial applications. This circuit breaker utilizes a combination of thermally-activated switches and adjustable magnetic latches that help protect the circuits against overloads. It also features an adjustable time delay, adjustable energy storage/delay rating, adjustable current rating, lockout/tagout capability, and adjustable LEDs to indicate the trip level. This combination of features makes the LEL111-2R-34173-1-V an effective and cost-effective solution for circuit protection.
