Alstom Single Phase Overcurrent AC Relay MVTU13T1BA0751H - by Areva T&D UL Ltd.

The Alstom Single Phase Overcurrent AC Relay MVTU13T1BA0751H stands as a highly reliable and precision-engineered solution designed specifically to protect electrical circuits from damage caused by overcurrent conditions. Engineered by Alstom, a leader in advanced electrical protection and automation, this relay delivers exceptional performance tailored for demanding environments within the power industry, petrochemical plants, and general automation systems. At its core, the MVTU13T1BA0751H is built to detect single-phase overcurrent faults with high sensitivity and rapid response times, ensuring minimal disruption and maximum safety. It features a robust input capacity compatible with standard AC voltage levels commonly found in industrial settings, offering accurate current monitoring for systems operating up to 600 V AC. 

The relay supports input currents typically up to 10 A, with configurable input ranges depending on the installation requirements. Its output contacts are rated for switching operations up to 250 V AC and 5 A, providing reliable tripping signals to circuit breakers or alarm systems. Durability is a key aspect of the MVTU13T1BA0751H. Constructed with high-quality insulating materials and sealed against dust and moisture ingress, it offers extended operational life in harsh industrial environments. The relay is tested to withstand temperature fluctuations from -20°C to +70°C, ensuring consistent performance across a broad range of climatic conditions. Its mechanical endurance exceeds 100,000 operations, supporting long-term reliability without frequent maintenance. Performance metrics emphasize fast response times, with trip activation occurring within milliseconds of detecting overcurrent conditions above preset thresholds.

This rapid action helps prevent damage to critical electrical assets and reduces downtime in power generation or automation processes. The relay’s adjustable time delay settings provide flexibility, enabling customization for specific applications and coordination with other protective devices. In real-world usage, the Alstom Single Phase Overcurrent AC Relay MVTU13T1BA0751H excels in protecting transformer windings, motors, and feeder lines in power plants and petrochemical facilities where electrical reliability is paramount. Its precise overcurrent detection helps avoid costly equipment failures and supports compliance with stringent safety standards. Within general automation environments, it safeguards control panels and machinery from overloads, contributing to efficient and safe plant operation.

When comparing the MVTU13T1BA0751H to other Alstom automation products, its specialization in single-phase overcurrent protection distinguishes it from multifunctional relays like the Alstom AL122A or the Alstom MVAJM14JB1004A1, which cater to broader protection roles including voltage monitoring and multi-parameter control. Unlike the Alstom RTS-13060102-R and RTS-61 models, which are primarily designed for three-phase systems, the MVTU13T1BA0751H focuses on single-phase scenarios, making it ideal for specific legacy or specialized installations. Additionally, the MVTU13T1BA0751H complements other Alstom relays such as the Alstom 20X4342/10, known for its overcurrent and earth fault protection, and the Alstom 20X4521/10, which offers time-delay functionalities suitable for complex coordination schemes.

The Alstom 30V7000/10 and 20X4334/30 series provide alternative solutions for high voltage applications, whereas the MVTU13T1BA0751H excels in medium voltage single-phase applications with precise sensitivity. Alongside the Alstom Single Phase Overcurrent AC Relay MVTU13T1BA0751H, we also offer the Alstom IC693PWR324X and Alstom IC693CMM311M, which serve as power supplies and communication modules respectively, enhancing overall automation system integration. The Alstom CMS2 and Alstom ALSPA MV500 relays provide advanced monitoring and multi-functional protection, making them ideal companions in complex installations requiring layered protection strategies.
