Protection relays & systems remain a critical asset in many electrical engineering applications. This is due to their ability to monitor and control electrical systems to ensure that any irregularities are corrected or the system is shut off in the event of an emergency. The SE-330AU-22-00 is a safety device designed to protect electrical systems from damage by regulating electrical flow in and out of a controlled system.

The SE-330AU-22-00 is designed for protection of three-phase current and voltage systems with a rated operational voltage up to 4kV AC (50-60Hz). It is a thermal protection relay designed to protect against the occurrence of overloads, arc-faults, short circuits, and line-to-ground faults. This is accomplished through the use of a multi-sensor system that is capable of detecting the overcurrent, voltage, ambient temperature, and rate of current rise. It also has the ability to detect the ambient temperature of the surrounding environment, providing additional protection against thermal overloads.

The main function of the SE-330AU-22-00 is to provide effective protection and coordination of the various components of the electrical system. This is achieved by the use of two distinct operating principles. The first is the purposeful application of electrical power, which acts as an on/off switch that controls the flow of power. The second principle is the control of the power in a way that protects the system from damage due to overloads or short circuits. This is accomplished by using a differential current sensing system, which senses the different currents in each phase and adjusts the power accordingly.

The SE-330AU-22-00 also has the ability to detect the loss of current in any one of the phases. This is important for applications where the full load current is necessary for operation but there is a risk of phase pitting and power loss. In this case the SE-330AU-22-00 will detect the loss in one of the phases and immediately turn off the power to the controlled system, thus providing protection against serious damage.

In addition to providing protection from the aforementioned events, the SE-330AU-22-00 also provides a number of maintenance and testing capabilities and is capable of operating even in extreme temperatures. This is made possible by the use of an intelligent system that adjusts the current regulation according to the ambient temperature. This ensures that the safety of the system is maintained at all times. Furthermore, the system is also equipped with self-test functions that can be used to carry out predictive maintenance protocols and early fault detection.

The SE-330AU-22-00 is suitable for use in all types of industries from industrial and agricultural applications to automotive and public utilities. It is particularly well suited for use in controlling motors and generators, and is often used in applications where line-to-ground faults are a major concern. With its range of sensing and protective capabilities, the SE-330AU-22-00 is one of the most reliable and effective protection relays available.
