The GIC MG21DF is a 3-phase monitoring relay for 208-480 VAC systems. It protects against under-voltage, over-voltage and single phasing, with an adjustable OFF delay to ride through short disturbances.
🔧 Technical Highlights:
- Supply: 208-480 VAC, 3-phase
- Functions: UV, OV and phase loss (single-phasing) protection
- Delay: Adjustable OFF delay
- Output: Relay contacts
✅ Benefits:
- Prevents nuisance trips on momentary dips
- Protects motors and drives from damaging voltages
- Ideal for wide-ranging plant supplies
🚀 Applications:
- Pumps, compressors and fans
- Material handling and conveyors
- General industrial control panels
MG21DF combines UV/OV and single-phasing protection with a practical OFF-delay for resilient control.
