Circuit breakers are frequently used in electrical systems to protect the wiring and devices connected to the mains from being damaged due to overcurrent or excess voltage. The IELHK21-29178-2-V is a common type of Circuit Breaker that provides these same features.

This particular breaker is used in 50 Hz AC electrical systems for protection against short circuit and overload. It is widely used in residential, commercial and industrial applications, including lighting switchboards, air conditioning systems, motor control panels, and various other electrical systems. This particular breaker is also suitable for use in higher voltage circuit applications, such as those found in substations.

The IELHK21-29178-2-V is a two-pole breakers that has a breaking capacity of 1000A for AC 50 Hz and 500A for AC 15kA. The rated voltage is 220/230 volts. It is made of polycarbonate material and is UL, CUL, and CE approved. In addition to providing overload, short circuit, and end of life protection, the IELHK21-29178-2-V also features manual reset, an indicator light, and is a semiconductor-based device that utilizes a translinear voltage-to-current converter.

The main components of the IELHK21-29178-2-V are a translinear converter circuit, a relay, current control logic, and a switch. The translinear converter circuit uses a voltage-to-current converter to detect and measure the current. When the current reaches a certain level, the relay is triggered which opens the circuit, thus breaking the current and protecting the other components. The switch is used to manually reset the breaker when it has tripped.

The current control logic helps to ensure that the circuit does not trip unnecessarily due to small fluctuations in the current. When a large increase in the current is detected, the logic will decide if the current is indeed dangerous and will then trip the relay to open the circuit if necessary. This feature allows the breaker to be used in motor control circuits as well, since the breaker can tell the difference between normal current fluctuations and dangerous levels of current. This helps ensure that the motor won\'t be damaged due to the breaker tripping unnecessarily.

The IELHK21-29178-2-V is a reliable and efficient circuit breaker that can be used in a variety of applications. Its features and protection capabilities make it ideal for use in residential, commercial, and industrial electrical systems. It is also suitable for use in higher voltage circuit applications, such as those found in substations.
