LELK1-1REC4R-33939-15-V

Circuit breakers are electrical switching devices designed to protect electrical circuits from overloads and damagingly high voltage surges. In terms of their primary functions, all circuit breakers are the same, but there are many variations with regard to their construction and configuration. The LELK1-1REC4R-33939-15-V is a type of circuit breaker commonly used for industrial applications, and this article will explain its application and working principle.

The LELK1-1REC4R-33939-15-V circuit breaker is a compact 3-pole breaker with a voltage rating of AC 600V, and is a high performance breaker suitable for a range of industrial applications. It is composed of a breaker body, interrupter contacts, an overcurrent protective device, a thermal-magnetic device, an arc-extinguishing chamber, and a control device which forms the core of some of the control options available.

The most basic application of the LELK1-1REC4R-33939-15-V is to function as a circuit protector. Its overcurrent protective device is designed to detect and trip the breaker if the current exceeds the pre-set limit, providing protection against overloads. The thermal-magnetic device ensures that the breaker is tripped in the event of a short circuit, providing fast and reliable protection for the connected circuit. The arc-extinguishing chamber allows the breaker to disconnect when arc faults occur, meaning that the circuit is not damaged by the resulting high voltage surge.

The LELK1-1REC4R-33939-15-V also offers control options, allowing its user to control the switching process remotely. This can be achieved either manually or automatically; in the manual mode, an external switch can be used to open or close the breaker remotely by sending a signal through a wire or radio frequency. On the other hand, in the automatic mode, the breaker can be programmed to close or open at predetermined times. This can be used to cycle the power on or off whenever required, without the need for manual intervention.

In terms of its working principle, the LELK1-1REC4R-33939-15-V operates in a similar manner to other circuit breakers. When the power is supplied to the breaker, the current flowing through the device trips the breaker if it exceeds a certain limit. If the current levels remain below the pre-set limit, the breaker will not trip and the circuit will remain powered. When the breaker trips, the contactors separate, thus disconnecting the circuit and protecting it from surges caused by accidental short circuits or overloads.

In conclusion, the LELK1-1REC4R-33939-15-V is a versatile circuit breaker suitable for a range of industrial applications. Its primary function is to provide protection from overloads and high voltage surges, with its various control options allowing the user to cycle the power on or off as and when required. In operation, the breaker is designed to trip if the current in the connected circuit exceeds a certain limit, with the contactors then separating so as to cut off the power.
