Circuit breakers are a vital safety device used in the electrical industry. They are a main element in the protection and control of all circuits and installations. The LELK11-39949-7-V is a type of circuit breaker used in the telecommunication industry. It is designed for use in challenging environments and is able to provide reliable protection even under extreme conditions. In this article, we will discuss the application field and working principle of the LELK11-39949-7-V circuit breaker.

The LELK11-39949-7-V circuit breaker is specifically designed to meet the demands of the telecommunication industry. It is available in two versions: a low voltage version, rated for up to 1000 volts, and a high voltage version, rated for up to 6000 volts. The circuit breaker is capable of breaking large currents, up to 2000 A, and is designed to be used in applications such as AC/DC switching, DC current control, and circuit protection.

The working principle of the LELK11-39949-7-V circuit breaker is based on electromechanical technology. It is designed to make and break electrical connections quickly and reliably. When the circuit breaker is turned off, an electromagnet is activated, which pulls a metal armature over the contacts on the device, thus breaking the circuit. When the circuit breaker is turned on, the electromagnet is deactivated, which allows for the armature to be released, allowing the contacts to make an electrical connection. This working principle ensures that the circuit breaker can be activated and deactivated quickly and reliably, ensuring that it is able to provide the necessary protection.

The LELK11-39949-7-V circuit breaker is designed for a wide range of applications, including AC/DC branch-circuit protection, back-up AC/DC circuit current control, and emergency circuit protection. It is ideal for use in industrial, commercial, and residential settings. It is compatible with both AC and DC power sources and is capable of operating at temperatures ranging from -30°C to +80°C.

The LELK11-39949-7-V circuit breaker is designed to provide reliable protection even under extreme conditions. It is certified to various national and international standards, such as UL 1077, CSA C22.2, and IEC/EN 60947-2. It is designed to be used in industrial, commercial, and residential settings and is capable of breaking large currents with a short time delay.

In summary, the LELK11-39949-7-V circuit breaker is a reliable safety device used in the telecommunication industry. It is designed to provide protection even under extreme conditions, and is certified to various national and international standards. It is ideal for use in a wide range of applications, such as AC/DC switching, DC current control, and emergency circuit protection. It is compatible with both AC and DC power sources and is capable of operating at temperatures ranging from -30°C to +80°C. The circuit breaker provides reliable protection in challenging environments and is able to make and break connections quickly and reliably.
