Circuit breakers are a common yet important device found in electrical systems. Generally, they are used to protect circuits from damage resulting from over current and short circuit conditions. If these conditions occur, the circuit breaker will trip, opening the connection and disconnecting the flow of electricity in the circuit. In this way, the circuit is protected from the damage that could be caused if the electricity was allowed to continue flowing.

IELHK1111-35550-80-V is a specific circuit breaker with the purpose of protecting low voltage AC motor drives. This circuit breaker utilizes a three-phase thermal-magnetic design. This designs includes both a thermal element and a magnet element.

The thermal element is responsible for protecting the device from current over-loads. The thermal element consists of a bimetal strip, which is designed to heat up once a certain temperature is reached. When the temperature exceeded the temperature required for protection, the strip will rapidly expand, causing the circuit breaker to trip, thus protecting the circuit from the excess current.

The magnet element of the circuit breaker is responsible for protecting the device from short circuits. The magnet component consists of a ferromagnetic core that is arranged along the current path. When a short circuit occurs, a large current will flow through the circuit, thus creating a large magnetic field in the core. This magnetic field causes the armature of the circuit breaker to be pulled in, tripping the circuit breaker and protecting the device from the high current that would occur during a short circuit.

The IELHK1111-35550-80-V circuit breaker is designed for use with low voltage AC motor drives. The low voltage means that there is not a high risk of damage due to excessive current. Therefore, the thermal element of the breaker acts as the primary protection, while the magnet element acts as a secondary protection. This approach provides a large degree of protection for the device, while also ensuring that the breaker will not trip unnecessarily due to low-level overloads.

The IELHK1111-35550-80-V circuit breaker utilizes a three-phase thermal-magnetic design to provide protection from over currents and short circuits. The thermal element is responsible for protecting the device from excessive currents, while the magnet element is responsible for protecting the circuit from short circuits. This circuit breaker is designed for use with low voltage AC motor drives and provides a high degree of protection for these devices.
