Circuit Breakers

IEG1111-1REC4-72-10.0-01-V is a circuit breaker commonly used in a variety of applications. In the context of an electrical system, a circuit breaker is a type of device designed to protect against dangerous currents and faults. It is designed to trip when the current in the circuit exceeds the level for which it is rated for, preventing possible damage to a building or its occupants.

The circuit breakers from the IEG1111-1REC4-72-10.0-01-V series are usually used in industrial applications, such as in power supply systems, on ships, locomotives, and in industrial plants, as well as in residential buildings for protection against short-circuits and overcurrents. The particular type of circuit breaker from the IEG1111-1REC4-72-10.0-01-V series is rated for a maximum of 10 amps and has a rating of 72 volts. It is used to protect both single-phase and three-phase systems.

The working principle of the IEG1111-1REC4-72-10.0-01-V circuit breaker is relatively simple. It has two parts which work together: the contact and the trip unit. The contact is the part of the circuit breaker which completes the circuit when it is closed and interrupts the circuit when it is open. The trip unit of the breaker detects when there is an abnormal current or short-circuit in the circuit and acts to open the contact, thus interrupting the circuit and protecting the system from damage.

In the case of the IEG1111-1REC4-72-10.0-01-V circuit breaker, the trip unit has a thermal element and an electromagnetic element. The thermal element works by detecting an increase in temperature caused by excessive current. The electromagnetic element acts to detect an increase in current as well as if there is a short circuit. The current is measured by the circuit breaker and is compared to the rated current of the breaker. If the current is above the rated level, the trip unit will open the contact, thereby interrupting the circuit.

In conclusion, the IEG1111-1REC4-72-10.0-01-V is a circuit breaker which is typically used in a variety of industrial applications. It is designed to protect against abnormal currents and faults by tripping the contact when the current in the circuit exceeds the level for which it is rated for. The working principle of the IEG1111-1REC4-72-10.0-01-V circuit breaker involves a contact and trip unit with a thermal element and an electromagnetic element. The thermal element acts to detect an increase in temperature, while the electromagnetic element detects excessive current and short circuits. When the current is above the rated level, the trip unit will open the contact and interrupt the circuit, thereby protecting the system from damage.
