Introduction: Circuit breakers are one of the most common types of electrical components found in the home, industry and virtually any other form of modern electric power. They are used to protect electric equipment from malfunction and electric shock, by interrupting the flow of electricity in an electrical circuit when an overload of current is detected. The LMLK1-1REC4-36464-25-V circuit breaker is a single-pole, thermal-magnetic switch, which has been specifically designed for the protection of low voltage systems.

Application Field: The LMLK1-1REC4-36464-25-V breaker is suitable for the protection of installations, equipment and circuits up to 25A carrying AC currents at 690V. Its primary use lies in the protection of domestic, industrial and commercial circuits, for example, in the protection of lighting circuits, domestic appliances, heating devices, pumps and motors, or any combination of these. The circuit breaker is typically used to switch loads on and off and to protect against the risk of thermal and/or magnetic-induced overloads. It is also ideal for use with overcurrent and short-circuit protection devices.

Working Principle: The LMLK1-1REC4-36464-25-V circuit breaker consists of two independent operating elements, a thermal element and a magnetic element which interact to offer reliable protection against overcurrent and short-circuit conditions. Operation is initiated by a thermal element at the pre-set overload current. When a current surge above the rated characteristics is detected, the thermal element causes an internal trip release. This functions at the same time as an electromagnetic force due to the flow of the excessive current through a force field, causing the magnetic’s internal trip release. The movement of an internal latch allows a mechanism to trip the breaker.

The circuit breaker’s short-circuit protection is provided by a separate magnetic element that senses and reacts to sudden fluctuation of current, such as a short circuit. When a short-circuit is detected, the electromagnetic force increases, breaking the contact between the two components and causing the internal latch to move and trip the breaker. When the current is to within pre-set characteristics, the thermal element and magnetic element reset themselves, enabling the breaker to be re-energized.

Safety Features: The LMLK1-1REC4-36464-25-V circuit breaker features a number of safety features to ensure the safe operation of electrical systems. The breaker incorporates a pressure-resistant, thermally insulated case which protects against any shock hazards, while also providing an enhanced level of insulation to ensure the system’s performance. The breaker is also equipped with a manual reset switch, which enables the user to reset the breaker without the need for any tools. Additionally, the breaker has an internal trip keeper which prevents it from being manually reset if the breaker has been tripped by the thermal element.

Conclusion: The LMLK1-1REC4-36464-25-V circuit breaker is an essential component of any electrical system, providing protection against overcurrent, short-circuit and thermal overload conditions. It is designed for the protection of domestic, industrial and commercial installations, and is certified to international standards for high quality and safety. With its innovative design, robust construction and comprehensive safety features, the LMLK1-1REC4-36464-25-V circuit breaker is an excellent choice for the protection of a variety of low voltage systems.
