Circuit breakers, also known as molded case circuit breakers (MCCB) or molded case switches (MCS),are an important and essential safety device in electrical installation. They are designed to protect circuits and people from any hazardous events such as overcurrent due to short circuit or overload. The IELHK11-1-72-30.0-01-V is one type of such a device.

The IELHK11-1-72-30.0-01-V is a three-pole, thermal-magnetic molded case circuit breaker that is suitable for use in various lighting, industrial, and commercial applications. It is suitable for circuit protection in a variety of AClow voltage power systems and can provide four levels of protection: overload, short circuit, under-voltage and service entrance protection. The IELHK11-1-72-30.0-01-V is capable of interrupting up to 30,000A of current at 500V AC. It is also fitted with a thermal flexible trip unit to offer precise protection.

The working principle of the IELHK11-1-72-30.0-01-V circuit breaker is quite simple. It relies on the thermal and magnetic effects of electric current to detect any overcurrent, overvoltage, or a short circuit in the system. The electric current passes through the breaker’s thermal element which is designed to sense any electric energy and then raises the breaker’s temperature until it reaches the breaker’s thermal overload set point. When the temperature of the breaker reaches the thermal overload set point, it triggers the release mechanism and breaks the circuit. On the other hand, the magnetic element of the breaker detects any over current or short circuit in the system and operates the breaker’s release mechanism.

The IELHK11-1-72-30.0-01-V circuit breaker can be used in multiple application fields. These include industrial installations, lighting applications, low voltage power and distribution system, motor and machine control, service entrance protection, fire pump circuits and emergency generator circuits. The circuit breaker can also be used as a disconnect switch in manual motor control and industrial equipment. It is also used in residential and commercial applications such as residential electricity meters and electronic HVAC controls.

The IELHK11-1-72-30.0-01-V circuit breaker is designed to provide the necessary safety measures to protect the circuits and people from any potentially dangerous scenarios. The device can detect any overcurrent, overvoltage, and short circuits in the system and disconnect the circuit to prevent any further damage. The device is also equipped with an overload trip unit to provide precise protection.
