Circuit breakers are electromechanical devices which are used to protect electrical circuits and equipment from excessive current or overload. The IALHK11-39345-15 is a medium voltage circuit breaker which is designed to provide reliable over-voltage protection and circuit isolation.

The IALHK11-39345-15 is a single pole circuit breaker, which is typically used in three phase systems with voltage ratings up to 15 kV. It has a rated current of 175 Amp and a rated short-circuit current of 65 kA. The operating temperature range is -25°C to +65°C and the operational time is less than 15ms.

The IALHK11-39345-15 has two independent over-voltage protection functions which can be used separately or in combination. The first is the thermal overload protection, which uses an integrated thermal overload relays which monitors and trips the breaker if the current exceeds the predetermined level. The second is the voltage protection, which uses an adjustable, very sensitive, voltage-sensitive switch which monitors the voltage level and trips the breaker in the event of an over-voltage condition.

The IALHK11-39345-15 also has a manually operated override switch, which can be used to manually trip the breaker in the event of an emergency. The breaker can be easily reset by pressing the reset button or by manually resetting the thermal overload relays.

The IALHK11-39345-15 also has two separate protection functions which can be used simultaneously. The first is the phase-neutral over-current protection, which uses an adjustable current setting to protect against over-currents. The second is the earth leakage protection, which uses an adjustable earth current setting to protect against earth faults.

The IALHK11-39345-15 has a contact arrangement of single-pole, two-way. This means that the contacts open in one direction and close in the other. This type of arrangement ensures that the breaker can be used in both phases of the alternating current supply, allowing for more flexibility than single-pole, double-throw breakers.

The IALHK11-39345-15 is a reliable and robust circuit breaker which has been designed to provide superior protection for electrical systems and equipment against overloading and over-voltage conditions. It is also easy to install and maintain, making it an ideal choice for many industrial applications.
