CAT1102013 is a type of short circuit current limiter designed to operate automatically in an AC electric power system. It is designed to prevent damage to a system when a short circuit occurs. The CAT1102013 is an electromechanical device that can be programmed to operate within specific operational parameters and curtails current during an overcurrent condition. The CAT1102013 is used in many different applications where current transient control is necessary in protecting electrical equipment from thermal damage due to overcurrent events, or where instantaneous protective devices cannot be used.

CAT1102013 application field mainly includes: current transient protection in equipment such as motors, drives and controllers; limiting peak currents in power distribution systems; protecting switchgear and circuit breakers from over-current operation; preventing high currents in inverter controllers; grid-level protection; and other applications where voltage and current transients are present.

The working principle behind CAT1102013 is based on a magnetic core which is saturated when a fault current exceeding the trip limit of the unit is applied. The core acts like a highly resistive material, reducing the current transmitted through it and hence, limiting the available fault current. The CAT1102013 operates in a highly predictable manner and its operation is independent of the system\'s voltage, load, and fault location.

When an overcurrent condition begins to outweigh the CAT1102013\'s static setting, the core is magnetized and begins to saturate. This causes the impedance of the saturable core to increase and leads to a rapid decrease in current. The magnitude of the reduced current flow is determined by the settings of the device, enabling predetermined shutdowns under different scenarios. CAT1102013s are designed to provide a safe and reliable solution to current levels which otherwise, could seriously damage electrical systems.

The CAT1102013 works by sensing the current, reactively inserting an inductive element into the path of the circuit to limit the fault current. This is done by controlling the electron-mechanical effects of a saturable core which is placed in the magnetic circuit of the device. Once the current in the CAT1102013 exceeds the set limit, the saturable core is saturated and the remaining flux builds up creating a resistive effect on the fault current. This effect allows the CAT1102013 to limit the fault current to a pre-determined level which can be set in accordance with the appropriate equipment rating.

The CAT1102013 is well suited for current control applications due to the fast response time. Typical reaction times are in the order of 4ms, with a response time as fast as 3ms. This allows the CAT1102013 to act before any thermal damage occurs, often limiting the fault current before it can cause any disruption. The device also helps to reduce harmonic distortion in electric power systems, helping to increase the overall lifespan of the system and maintain high levels of safety.

CAT1102013s are reliable, durable and easy to operate, making them an essential component in protecting electrical power systems. As a cost-effective device, CAT1102013s prove to be an economical solution to current limiting applications in distributed energy networks, wind turbine generator systems and other applications.
