Circuit Breakers are an important safety feature in most electrical systems, providing protection against power surges and overloads. The LELK121-1REC5-38760-50-G2-V is an example of a circuit breaker that provides an efficient and reliable way to protect against overcurrent. In this article, we will discuss the application field and working principle of the LELK121-1REC5-38760-50-G2-V.

Circuit breakers are generally used to protect circuits from electrical overloads, reducing the risk of a fire or an electrical accident. The LELK121-1REC5-38760-50-G2-V circuit breaker is designed for use in residential, commercial and industrial applications. It is suitable for a range of AC current, from 20 to 50 Amp. Its operating temperature ranging from -25°C to +65°C, and a suitable frequency of 50/60Hz allows for a greater flexibility in use. This device complies with the UL 489A/B, CSA 22.2 standards, which is a safety requirement for equipment designed to be used in areas with high electrical load.

The LELK121-1REC5-38760-50-G2-V operates through the principle of thermal-magnetic trip technology. This means that the current is monitored by heat-sensitive components in the device. When the current reaches a specified maximum, the temperature of the device increases until the current is limited by the thermal switches, tripping the circuit breaker. This prevents any further current exceeding the maximum limit.

The LELK121-1REC5-38760-50-G2-V also features a magnetic trip device. This device responds to excessive current events by either tripping the circuit breaker outright or by providing a delay to reduce the effect of the current event. This delay can help to prevent circuit overloads, reducing the risk of fire or other damages to the circuit.

In addition to its thermal and magnetic trip capabilities, the LELK121-1REC5-38760-50-G2-V is also equipped with a mechanical indicator which provides a visible indication of the circuit trip event. This feature allows users to quickly and easily identify when the current has exceeded the maximum limit, allowing them to take the appropriate corrective action.

Overall, the LELK121-1REC5-38760-50-G2-V circuit breaker provides an efficient and reliable way to protect against overcurrent. Its compliance with safety standards and its combined thermal and magnetic trip mechanisms make it suitable for a wide range of applications, from home and office installations to industrial installations. The included visibility indicator further enhances the device’s usefulness, making it a great choice for monitoring current levels and preventing electrical overflows.
