The ALSTOM MCRI01T1CD0751C is a type of overcurrent relay that is commonly used in electrical protection systems. These relays are designed to detect overcurrent conditions and provide a protective function by tripping a circuit breaker or isolating equipment to prevent damage.

### Key Features of Overcurrent Relays:
1. **Protection Functionality**: They monitor the current flowing through a circuit and trigger an alarm or trip the circuit when the current exceeds a predetermined level.

2. **Settings and Coordination**: Users can set the pickup current level and time delay based on the application requirements. This allows for coordination with downstream devices to prevent nuisance tripping.

3. **Multiple Operating Modes**: Many overcurrent relays, including models from ALSTOM, may offer various operating modes, such as inverse time characteristics, definite time, and instantaneous tripping.

4. **Communication and Data Logging**: Advanced relays often have communication capabilities (like Modbus or IEC 61850) to integrate with larger control systems and can log operational data for analysis and troubleshooting.

5. **Environmental Considerations**: Designed to operate effectively in various environmental conditions, these relays often have ratings for temperature and humidity.

6. **User Interface**: Many units feature a display for real-time monitoring of current levels, settings, and event logs.

### Applications:
– Used extensively in power plants, substations, and industrial locations to protect transformers, generators, and feeders from overcurrent conditions.
– Suitable for both large-scale utility applications and smaller industrial settings.

### Maintenance:
– Routine testing and calibration may be necessary to ensure proper operation.
– Keeping firmware updated (if applicable) can enhance performance and add features.
