Protection relays and systems are devices used to provide safety in electrical power systems. The SE-330HV-01-01 is a three-phase over-current circuit breaker. It is designed to ensure that current in an electrical circuit does not exceed its Rated Maximum Interrupting Capacity (RMIC) — the maximum amount of current the device can carry safely without damaging itself or other equipment downstream, or causing a fault on the power system.

The SE-330HV-01-01 is an inherent trip unit with a long history of proven performance and user-friendly features. It is designed for use in medium and high voltage applications ranging from 3.3 up to 38 kV. It is suitable for use as a protection device for transformers, motors, system lines, capacitors, and other medium-voltage equipment. It can also be used as a lock-out relay for open-door safety and for interlocking features in distribution switches.

The SE-330HV-01-01 is a self-powered current-sensing, time-delay motor-operated circuit breaker. It is designed to sense and respond quickly to unexpected faults and overcurrents in the electrical system. It is designed to interrupt electrical faults up to its rated maximum available short-circuit current (MCSIC).

The SE-330HV-01-01 has four built-in protection features designed to protect personnel, equipment, and premises from electrical hazards. The first two features are: instantaneous protection, which operates within 2 milliseconds of a fault; and time-delay protection, which allows a preset time to pass before the fault is interrupted. These two features make the breaker responsive and reliable in protecting personnel and equipment against unpredictable overcurrents and short-circuits.

The SE-330HV-01-01 also has two other protection features: undervoltage protection and overload protection. The undervoltage protection prevents the breaker from operating if the voltage falls below a preset value, while the overload protection allows the breaker to trip when a predetermined current level is exceeded. These features ensure that the breaker will only operate when necessary, while providing a high level of protection for personnel and equipment.

In addition to the above features, the SE-330HV-01-01 has a number of other features that make it an attractive and cost-effective solution for protection against unexpected overcurrents and short-circuits. It is a self-powered device, meaning that it does not require any external power source to function. Furthermore, the SE-330HV-01-01 features a wide range of adjustable settings and allows for remote monitoring and control of the device. This makes it suitable for applications that require flexibility.

Overall, the SE-330HV-01-01 is an excellent solution for protection applications such as transformer, motor, system line, and capacitor protection. Its features make it a cost-effective and reliable solution for many medium- and high-voltage applications. With its wide range of adjustable settings and remote monitoring and control capabilities, the SE-330HV-01-01 is an ideal choice for many applications.
