Product overview
The VTEKE VCR-02 is a voltage control relay designed to protect electrical systems and equipment against abnormal voltage conditions in three-phase applications. It monitors the supply voltage and provides protection against overvoltage, undervoltage, insufficient supply voltage, phase failure, and neutral absence.
Applications
- Designed for monitoring and protection applications. Suitable for:
- Motor protection systems
- Pumps and compressors
- Industrial machinery
- HVAC systems
- Control and automation panels
- Distribution panels
Key features
- Overvoltage and undervoltage monitoring
- Phase failure protection
- Neutral absence detection
- Insufficient supply voltage detection
- Adjustable overvoltage and undervoltage thresholds
- Adjustable delay time
- Adjustable reset time
- LED status and fault indication
- DIN rail mounting
