Circuit breakers are an important and often overlooked part of any electrical system. As their name implies, circuit breakers protect circuits from overloading or miswiring and allow for safe power distribution. The LEL1-27350-1 is an example of a circuit breaker with a specific application field and defined working principle.

The LEL1-27350-1 is a miniature circuit breaker (MCB) utilized in low-voltage applications. It is a single pole MCB rated at 10A and interchangeable between the 1P, 2P and 3P MCB ranges. The breaker has a rated short circuit capacity (Ics) of 10kA for 1 second and a rated ultimate short circuit capacity (Icu) of 10kA for 1 second. The maximum breaking capacity for 1P and 2P breakers is 6kA.

The LEL1-27350-1 is designed for low power applications and is suitable for DC or AC circuits operating from 10 to 250 volts. It is approved for use in domestic, commercial, and industrial applications. The breaker has a long expected life, making it a reliable choice for a variety of electrical applications.

The working principle of the LEL1-27350-1 is based on the use of a thermal magnetic protection system. This type of protection uses both thermal and magnetic elements in order to trip the breaker when the current level reaches a dangerous level. The thermal element is responsible for detecting any sustained currents that exceed the rated current of the breaker while the magnetic element is used to detect any momentary or intermittent overcurrents.

The breaker also has a manual reset button which helps to reset the breaker after it has tripped. The reset must be done manually, as the breaker will not reset itself automatically. It is important to ensure that the breaker is not continuously resetting, as this could indicate a fault in the electrical system.

In addition to its thermal magnetic protection system, the LEL1-27350-1 also boasts a host of other features to ensure its safe and reliable operation. These include a rapid trip response time and a noise suppression system to reduce radio frequency interference. The breaker also incorporates a surge protective device to protect against both automatic power recovery and undervoltage conditions.

The LEL1-27350-1 is designed for use in a wide range of applications including domestic, commercial, and industrial. It is a reliable and cost-effective option for low power applications that require reliable protection against overcurrents and undervoltage scenarios. With its thermal magnetic protection system and host of other features, the breaker provides a safe and reliable solution for any electrically powered system.
