Circuit Breakers

The IELH111-1REC4-26047-1-V is a circuit breaker that is used in a broad range of applications to provide reliable and safe shutting off of electric circuit. It is often used to protect a building or home from electrical overloads, short circuits and ground faults. It helps to reduce the risk of damage to electrical equipment and even possible electrocution.

Application Field

The IELH111-1REC4-26047-1-V circuit breaker can be applied in a variety of residential, commercial and industrial environments. It is commonly used in electrical wiring systems such as a distribution panel, which is used to distribute power from the source of supply to the various power terminals. It is also used in motors, to protect against accidental motor overloads, and in switchgear for surge protection and arc fault protection.

The IELH111-1REC4-26047-1-V can also be used in circuit breakers that are used to protect electrical equipment in industrial settings, such as high-voltage circuit breakers or circuit breakers that are used to protect electrical equipment in healthcare facilities, such as MRI machines, CT scans, etc. They are also used in marine applications, such as in shipboard electrical panels.

Working Principle

The working principle of the IELH111-1REC4-26047-1-V is based on the principle of electro-mechanical interaction. When an over-current or short-circuit occurs, the circuit breaker trips and interrupts the electrical circuit. This is achieved by using a bimetal strip, which consists of two materials that have different thermal expansion coefficients. When current passes through the strip, the strip warps due to the heat generated and releases a mechanical movement.

This mechanical movement causes the circuit breaker to trip, which in turn interrupts the electric circuit. The breaker can then be manually reset by pulling the trip lever to reset the contact points on the circuit breaker. The resetting of the circuit breaker restores the circuit to a safe state, preventing further damage from occurring.
