LMLB1-1RLS4-35530-3-V

Circuit breakers are protective devices that safeguard electronic and electrical circuits from short circuits and overloads. They protect not just the circuit and the power supply, but also people and equipment from electrical shock injuries. LMLB1-1RLS4-35530-3-V is a model of a 3-pole circuit breaker that is designed for residential, commercial, and industrial applications. This article will discuss the application and working principle of the LMLB1-1RLS4-35530-3-V circuit breaker.

Application of LMLB1-1RLS4-35530-3-V Circuit Breaker

The LMLB1-1RLS4-35530-3-V circuit breaker is designed to provide circuit protection for three-phase applications in residential, commercial and industrial settings. It has a voltage rating of 480Y/277VAC, and can interrupt up to a 65kAIC@240VAC short circuit current. It is UL 1053, UL 98, and UL 489 listed, and features a number of different adjustable trip settings, as well as a trip indicator light. It also meets CSA C22.2 No. 14, and IEC 60947-2 requirements.

It has a wide range of applications due to its compact size and low operating temperature. It is recommended for use in residential and commercial homes, commercial buildings, and large industrial applications including power plants and substations. It is rated for up to 100A of continuous current, and can be used to protect a wide variety of loads such as lighting, heating, air conditioning, fans, pumps, and compressors.

Working Principle of LMLB1-1RLS4-35530-3-V Circuit Breaker

The LMLB1-1RLS4-35530-3-V circuit breaker uses the traditional inverse time-delay protection to ensure that circuit breakers respond to overload conditions and short circuits. When a short circuit or an overload occurs, the current flowing through the circuit breaker increases dramatically. The circuit breaker has an integrated magnetic trip mechanism that senses the current flowing through it and triggers an internal time delay, which causes the contacts to open after a predetermined amount of time.

The trip mechanism is adjustable, so the user can choose the amount of time it takes for the contacts to open in response to a surge in current. This allows the user to choose a trip threshold that is suitable for their application. The trip mechanism is designed so that the circuit breaker will not trip prematurely in the event of a mild overcurrent, but will still react quickly if a more serious fault occurs.

The LMLB1-1RLS4-35530-3-V circuit breaker also incorporates a current transformer that monitors the current flowing through the connected load. When an overcurrent or a short circuit occurs, the current transformer produces a signal that activates a relay that opens the circuit breaker contacts. This ensures that the connected load does not become damaged and prevents further damage to the circuit and power supply.

The LMLB1-1RLS4-35530-3-V circuit breaker is designed to provide protection in residential, commercial and industrial settings. It has a compact size, adjustable trip settings, and meets multiple safety regulations. It is recommended for applications that require circuit protection for up to 100A of continuous current. Its integrated magnetic trip mechanism, current transformer, and trip indicator light make it an ideal choice for circuit protection.
