Inrush Current Limiters (ICL) are widely used in many fields such as motors, compressors, circuit breakers, UPS, and lighting circuits. The main application of an ICL is to protect against inrush current overloads. In order to keep the system safe from surge and inrush currents, it is essential to modify the device’s behavior momentarily to limit peak inrush currents. This is accomplished by the use of an inrush current limiter. This type of device is typically used to protect circuits from sudden high inrush currents that occur during start up, while still allowing standard levels of current for normal operation.The MS15 15004-A Inrush Current Limiter is a circuit breaker type ICL that is ideal for protecting motors, compressors, transformers, and other electric circuits from risks associated with inrush current overloads. The design utilizes thermal dynamics to protect circuits from inrush current damage. It limits inrush current, suppresses start-up noise, and ensures circuit integrity. This ICL is manufactured with a carefully selected thermal material for rapid thermal capacity and a terminal that is designed to provide quick and accurate connections.The working principle of the MS15 15004-A ICL is based on the device’s ability to accurately measure the peak current and then cuts off the supply of current in the event that the peak current exceeds the limit set by the user. This precautionary measure helps to protect the circuit from overload and hence prevent inrush current related damage. The thermal material of the device is carefully selected to ensure that it has the capacity to absorb and dissipate the inrush current without tripping the breaker or causing any circuit failure. When the power is initially turned on, the device enables rapid current flow to the load, allowing the motor or other devices to reach full speed and obtain the desired torque. After a certain time period, the current will start to slow down due to resistance in the circuit, and the device will respond by gradually reducing the current supply. The thermal material of the device detects the passing of current and absorbs and dissipates the inrush current before the set limit is exceeded.This inrush current limiter also features a soft start functionality, which enables the unit to start slowly and then gradually speed up, avoiding any sudden increase in current. This feature is especially beneficial in applications such as compressors, pumps, and electric motors, where sudden current fluctuations can cause damage to the system.Overall, the MS15 15004-A Inrush Current Limiter is an ideal device for protecting circuits from excessive currents. It is designed to be easy to install and maintain, and its thermal material allows for accurate and fast current readings, limiting the inrush current to the desired levels and avoiding any circuit failure. The unit is capable of withstanding strong electromagnetic fields and has excellent cold flow properties, which ensures that it is able to accurately measure and limit current for prolonged periods of time.
