Protection relays and systems are important components of the electrical system. The MPU-32-00-01 is an integrated multifunction three-phase protection unit that can be used to provide over current, under voltage and overvoltage protection in three-phase power systems. It is used in industrial, commercial, and residential applications.

The MPU-32-00-01 is designed to protect electrical devices in three-phase systems. It is a type of overcurrent protection device that constantly monitors the current in the system and quickly responds to abnormal current conditions by tripping the breaker. This helps to prevent damage to property and personnel caused by overloads and short circuits.

The MPU-32-00-01 has a built-in instantaneous trip release that is activated when an overcurrent condition exceeds the preset limit. The trip release is enabled or disabled by a button located on the unit. It is also equipped with a voltage monitor that senses undervoltage and/or overvoltage conditions and trips the breaker.

The working principle of the MPU-32-00-01 is based on the measurement of the current flowing through the system. The current is measured in terms of Amperes (A) and if it exceeds the set limit, the relay will release the trip. The trip circuit is also equipped with a voltage monitor which ensures that the supply voltage does not drop below a certain predetermined level or rise above another level. If either of these conditions is detected, the trip will be released.

Most often the MPU-32-00-01 will be used in branch circuit protection of three phase equipment. The unit is designed to provide overcurrent, undervoltage, and overvoltage protection. It is used to protect motors, heaters, AC units, and any other type of electrical device in a three-phase system against overloads and short circuits. The trip feature of the unit ensures that any abnormally high current is quickly and reliably disconnected.

The MPU-32-00-01 is an integrated multifunction three phase protection unit that is used to protect and disconnect an electrical device in a three phase system from overloads and short circuits. It features an instantaneous trip release and a built-in voltage monitor to ensure that negative or positive voltage surges are quickly disconnected to prevent damage to property and personnel. The unit is an efficient and reliable protection device for use in three-phase systems.
