LELK1-1REC4-31551-70-V

Circuit breakers are devices that are designed to open and close an electric circuit by interrupting the flow of current. The LELK1-1REC4-31551-70-V circuit breaker is an example of such a device. Specifically, this circuit breaker is designed for use in motors or other electric circuits where high mechanical and electrical performance are required. It is rated for a maximum breaking capacity of 5kA and a maximum short-circuit capacity of 10kA.

When connected to an electrical circuit, the LELK1-1REC4-31551-70-V circuit breaker first detects the current running through it. When the current reaches an unsafe level, either because of a short circuit or an overload, the circuit breaker turns off the power supply and opens the circuit, protecting the electrical system and its components from damage. When the cause of the overload or short circuit is remedied, the circuit breaker can be reset and power restored.

The LELK1-1REC4-31551-70-V circuit breaker utilizes a combination of both thermal and magnetic technology to detect faults and to interrupt the current. When the current running through the circuit breaker reaches a certain level, a temperature-sensitive element within the device trips, initiating a process to break the circuit. At the same time, an electromagnet within the device is energized, causing the circuit breaker\'s contacts to separate, effectively opening the circuit and stopping the supply of power.

Due to its combination of thermal and magnetic protection, the LELK1-1REC4-31551-70-V circuit breaker is suitable for applications where current levels can change quickly, such as on electric motors where the level of current can rapidly increase as the motor accelerates. By utilizing thermal and magnetic protection, the circuit breaker can react nearly instantly, protecting both the motor and the electrical system in general from damage due to overcurrent or short circuits.

The LELK1-1REC4-31551-70-V circuit breaker offers a range of other benefits, such as its high breaking capacity, long service life and small size. This makes it suitable for a variety of applications and installations, including industrial and commercial applications.

In conclusion, the LELK1-1REC4-31551-70-V circuit breaker is a device designed for use in circuits where high mechanical and electrical performance are required. By combining thermal and magnetic protection, it is able to efficiently detect overloads and short circuits, quickly interrupting the flow of current and protecting the circuit from damage. Its various features and benefits make it ideal for a variety of applications and installations, such as industrial and commercial circuits.
