IEL111-24943-1-V is a type of circuit breaker, typically used in power systems to protect heavy industrial and commercial equipment. It is designed to protect high-voltage circuits from overloads or short circuits by breaking the circuit when a certain threshold is exceeded. The device has a rated voltage of 11.5kV and an interrupting capacity of 200kA.

A circuit breaker consists of several components, including a switch, an overcurrent or short circuit protection device, and a control system. The switch in a circuit breaker is normally open and remains closed when there is no current flowing through the circuit. When a fault occurs, an internal trip mechanism is activated, causing the switch to open and thus breaking the circuit. In this way, the circuit breaker is able to prevent damage to equipment and other components that could be caused by an overload or short circuit.

When it comes to working principles, IEL111-24943-1-V employs a variety of technologies, which vary depending on the type of circuit breaker. For example, some circuit breakers use thermal overload protection, which monitors the current flowing through the circuit and trips the breaker when the current exceeds a certain threshold. Other circuit breakers use magnetic overload protection, which works in a similar way but uses the energy generated by a small magnet to trip the breaker when too much current is present. In either case, once the circuit breaker has detected an overload or short circuit, it opens and breaks the circuit, preventing further damage.

The IEL111-24943-1-V is used mainly for the protection of heavy industrial and commercial equipment, such as transformers, lighting systems, air conditioning units, and other electrical appliances. It offers high-voltage protection and is designed to withstand interrupting current up to 200kA. It is also suitable for the protection of three-phase system equipment.

IEL111-24943-1-V is a reliable and robust circuit breaker that offers high-performance protection for electrical circuits. Its varying technologies offer protection from overloads and short circuits, while the control system helps optimize its performance and ensure the safe and efficient operation of the equipment it serves.
