The Siemens SIPROTEC 7UM6115-5EC92-0FA0/EE generator relay is an advanced protection device designed for generators and engine-starting applications. This model is a part of Siemens' SIPROTEC 7UM series, which provides superior performance and reliability for power generation systems.
The 7UM6115-5EC92-0FA0/EE relay is a roller contact relay with an electronic overload and over temperature protection function. It is engineered to reliably protect generators against various faults, ensuring their optimal performance and longevity. The relay features a user-friendly design, allowing for easy installation and operation.
The electronic overload protection function monitors the current flowing through the generator and automatically trips the circuit breaker when the preset limit is exceeded. This prevents damage to the generator caused by overloading. The over temperature protection function monitors the generator temperature and trips the circuit breaker if the temperature rises above the defined limit. This prevents damage to the generator caused by overheating.
The 7UM6115-5EC92-0FA0/EE relay also offers excellent immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring reliable operation in electrically noisy environments. The relay is designed to comply with IEC 60255-2 standards.
The relay's contact rating is 630A at 250V AC, with a total contact capacity of 2.5 kVA. It features seven contacts, including three normally open (NO) contacts for overload, over temperature, and fault protection, and four normally closed (NC) contacts for start, stop, run, and fault indications.
The 7UM6115-5EC92-0FA0/EE relay includes a built-in test function, which allows for easy verification of its functionality and protection settings. It also features a testing current of 100mA, ensuring that the contacts function properly even when the main load is disconnected.
The housing of the relay is constructed from insulating material and is front-accessible, which allows for easy replacement of the relay in the field. The relay is designed for operation in air-conditioned environments with a temperature range of 5 C to 40 C. Overall, the 7UM6115-5EC92-0FA0/EE generator relay is a robust and reliable protection device that is essential for ensuring the optimal performance and longevity of generator systems.
