Circuit Breakers

A circuit breaker is an electrical switch which is used for protection against excessive current in an electrical circuit. The use of circuit breakers is necessary to prevent damage to electrical equipment and risk of fire due to overheating of the circuit or a short circuit. Circuit breakers are designed to automatically detect faults and turn off the circuit when necessary. To enable the safe operation of electrical networks, circuit breakers must be designed to a very high standard to ensure they perform their protective role effectively.

IUL1-1REC4-61-50.0-A-01 Application Field and Working Principle

The IUL1-1REC4-61-50.0-A-01 circuit breaker is a high performance, robust breaker with a range of features for protection against short-circuits, overloads and earth faults. The circuit breaker is suited for use in a variety of industrial, commercial and residential applications. It is suitable for the protection of medium-voltage power systems in both indoor and outdoor locations.

The operation of the IUL1-1REC4-61-50.0-A-01 circuit breaker is based on the use of a bimetal strip which is heated by the current flowing through it. When the current reaches a certain level, the strip bends, causing the contacts to separate and trip the breaker. This ensures that the circuit is protected against excessive current, thereby preventing damage to the electrical system or the risk of fire. The circuit breaker also has an adjustable sensitivity setting which allows it to be adjusted to trip at different levels of current.

The IUL1-1REC4-61-50.0-A-01 circuit breaker also has additional features such as a thermal-magnetic trip unit, a flexible start-up current setting and an adjustable current range, as well as power and Earth leakage circuit interruptors. This allows the circuit breaker to provide a wide range of protection from a variety of potential faults, ensuring it is suitable for a range of applications.

The IUL1-1REC4-61-50.0-A-01 circuit breaker is an efficient and reliable protection device for medium-voltage power systems. With its adjustable sensitivity and range of features, it is suitable for a wide range of applications and is ideal for protecting your electrical equipment from short-circuits, overloads and earth faults.
