ABB MPRB 99-1.0-GF relay

ABB MPRB 99-1.0-GF relay

Application: It is mainly used in ABB SafeRing/SafePlus series SF6 insulated ring network cabinets and compact switchgear, which are used for transformer protection and other functions, and used with vacuum circuit breakers and other equipment.

Functional characteristics
Protection function: With over current protection, over voltage protection, under voltage protection and other basic protection functions, can be a full range of electrical equipment protection. When the current and voltage in the circuit are abnormal, it can act quickly to cut off the circuit to prevent the equipment from being damaged due to overcurrent and overvoltage.
Measurement and monitoring: the current, voltage and other parameters in the circuit can be measured and monitored in real time to provide accurate electrical data for the system, so that the operator can understand the operating status of the equipment in time.
Signal output and communication: with signal output interface, the measurement data and protection action signal can be transmitted to other control equipment or monitoring system, to achieve remote monitoring and automatic control.

Technical parameter
Rated voltage: The voltage level suitable for equipment such as ring cabinet, usually 12kV.
Rated current: Applicable to different application scenarios and configurations, such as 630A or 1250A rated current.
Accuracy level: High measurement accuracy, such as current measurement accuracy may reach 0.5% or higher, voltage measurement accuracy can also meet the requirements of the power system.
Action time: When a fault occurs, it can respond quickly, and the general action time is within tens of milliseconds to ensure timely protection of the device.

Product advantage
High reliability: The use of high-quality materials and advanced manufacturing processes, through strict quality testing, can operate stably in harsh industrial environments, with a long service life.
Easy installation: compact design, reasonable structure, easy installation and maintenance, can be directly installed in the ring network cabinet or switch cabinet on the corresponding position, reducing the installation space and time cost.
Strong compatibility: It can be well compatible with other electrical equipment and automation systems of ABB to achieve seamless docking, convenient for users to integrate and expand the system.
