Protection Relays
Three-Phase Failure and Sequence Protection Relay without Neutral (3P)
ModelPPR-06F
Product overview
The VTEKE PPR-06F is a phase failure relay designed to protect three-phase electrical systems and equipment against abnormal phase and voltage conditions. It monitors the three-phase supply and provides protection against phase failure, phase sequence error, voltage asymmetry, overvoltage, undervoltage, and insufficient supply voltage.
Applications
- Designed for monitoring and protection applications. Suitable for:
- Three-phase motor protection
- Pumps and compressors
- Industrial machinery
- HVAC systems
- Control and automation panels
- Distribution panels
Key features
- Phase failure monitoring
- Phase sequence error protection
- Adjustable voltage asymmetry protection
- Overvoltage and undervoltage protection
- Insufficient supply voltage detection
- Adjustable delay time
- Adjustable reset time
- LED status and fault indication
- DIN rail mounting
