Circuit breakers are an essential component in any electrical system to prevent overloads, short circuits, and external faults. In particular, the LMLB1-1RLS4-35530-11-V is a thermal-magnetic circuit breaker designed for switching and protection of low voltage systems. It features an adjustable trip unit with fast tripping response times, excellent isolation properties, and high contact current ratings.

The main application field of the LMLB1-1RLS4-35530-11-V is residential and light commercial electrical systems. It is used to protect lighting, heating, or air conditioning circuits, as well as other low voltage circuits such as telephone and intercom systems. It can also be used in hazardous locations such as industrial processes and medical facilities.

The working principle of the LMLB1-1RLS4-35530-11-V is based on the combination of overheating, overcurrent, and short-circuit protection. This is achieved by a thermal-magnetic trip unit, which consists of a thermal element and a magnetic element. The thermal element will cause an increase in temperature when the current increases and will trip the circuit breaker when a pre-determined temperature is reached. The magnetic element, on the other hand, will trip when an overcurrent is detected, resulting in an uninterrupted power supply.

The LMLB1-1RLS4-35530-11-V offers several features that make it an ideal choice for different applications. First, it features voltage ratings of 690V AC and 500V DC. The adjustable trip unit allows the user to select the current rating that best fits the intended system. Additionally, the compact design of the circuit breaker allows for easy installation and maintenance. Moreover, it provides excellent isolation properties for increased safety.

The LMLB1-1RLS4-35530-11-V is a highly reliable and robust circuit breaker designed for residential and light commercial applications, providing fast tripping response times and excellent isolation properties. With adjustable current ratings and a compact design, it is an ideal choice for various low voltage applications, such as lighting, heating, and air conditioning circuits. Additionally, its high contact current ratings make it suitable for hazardous locations, such as in the industrial or medical fields.
