SE-325T

SE-325T is a three-phase monitoring relay which provides protection for motors and other equipment by monitoring the system currents and voltage. The device supports multiple functions such as over/under current protection, phase reversal protection, short-circuit protection, phase unbalance protection, current leakage protection and monitoring of motor overheating. It has a current range of 12mA to 25A and a voltage range of 15V to 600V . The SE-325T can help reduce downtime and improve the efficiency of motors and related equipment.

Application Field:

SE-325T is primarily used to protect motors and other related equipment by monitoring the system for faults. It is designed to provide reliable protection for equipment from overloading, short circuiting and other abnormal electrical conditions. The protection features of the SE-325T make it an ideal choice for applications such as motors, pumps, compressors, air conditioners, lighting systems, and many other industrial applications that require reliable protection.

Working Principle:

The SE-325T works by monitoring the incoming currents and voltage and then performing various protection and detection functions based on pre-set thresholds or settings. It monitors the incoming currents and voltages against pre-defined thresholds to detect any type of overload or over voltage conditions. If any current or voltage exceeds the thresholds defined, the SE-325T will immediately initiate the corresponding protection action. The protection action of the SE-325T depends on the configuration - a short circuit trip, an alarm, a shutdown of the system or something else.

The SE-325T can also provide phase-failure protection and detect when one phase of a motor or related equipment is not working normally. In the event that one phase of a motor fails, the SE-325T will send a fault signal and stop the motor in order to protect it from damage. The SE-325T also provides short-circuit protection for motors and other related equipment, by automatically cutting off the supply if a short circuit occurs.

Conclusion:

The SE-325T is a reliable and efficient three-phase monitoring relay designed to provide reliable protection for motors and other related equipment. Its various monitoring and protection functions make it an ideal choice for applications such as motors, pumps, compressors, air conditioners, lighting systems, and many other industrial applications that require reliable protection.
