IUGN11-1REC4-53-15.0

Circuit Breakers

A circuit breaker is a device designed to protect electrical circuits from damage caused by overcurrent, overload or short circuit. The IUGN11-1REC4-53-15.0 is a particular type of circuit breaker – a thermal-magnetic circuit breaker – which is used to protect circuits from overcurrent caused by either long-term overload or short circuit. The thermal element of this circuit breaker uses a bimetallic strip to detect excessive current; when that current is exceeded, the contacts open, shutting off the electrical power. The magnetic element is designed to detect short-circuits and also operate rapidly enough to protect the circuit from extreme overcurrent.

Application Field

The IUGN11-1REC4-53-15.0 is designed to protect circuits from overcurrent due to overload or short circuit. It is commonly used to protect lighting circuits, heating and air conditioning, computers, pumps, motors, or other circuits that require protection from current spikes. The breaker is designed to trip when the current reaches 15.0 amperes. It is suitable for use in residential, commercial, and industrial applications, including ships, off-shore rigs, and factories.

Working Principle

As mentioned, the IUGN11-1REC4-53-15.0 is a thermal-magnetic circuit breaker. This type of breaker is designed to protect circuits from both overload and short circuit. It works by detecting excessive current using both a thermal element and a magnetic element. The thermal element consists of a bimetallic strip that expands when heated by the current. This expansion causes a contact arm to open, which shuts off the electrical power. The temperature-sensing element can detect small overloads over a long period of time.The magnetic element consists of a coil, an armature, and a contact arm. When an excessive electrical current flows through the coil, a magnetic field is generated – enough to force the armature against the contact arm and open the circuit. This allows the breaker to trip quickly when large surges or short circuits occur.

Conclusion

The IUGN11-1REC4-53-15.0 is an example of a thermal-magnetic circuit breaker, designed to protect circuits from overcurrent due to either overload or short circuit. Its thermal element uses a bimetallic strip to detect overloads over a long period of time, and its magnetic element is designed to detect short circuits and act quickly to protect the circuit from extreme currents. It is suitable for use in residential, commercial, and industrial applications, and is designed to trip when the current reaches 15.0 amperes.
