Phase protection relay plug

Compressor Protector & Voltage Guard
Designed for coffee machines, refrigerators, freezers, and other electrical appliances

This device is specially engineered to protect compressors from damage caused by power fluctuations such as undervoltage, overvoltage, or power surges. It helps extend the lifespan of your compressor and ensures safe, reliable operation.

• If the voltage drops or rises beyond ±20% of the normal range, the relay will automatically cut off the circuit to prevent damage.

• Once the voltage returns to normal, the system activates a delay timer allowing the refrigerant inside the unit to stabilize before restarting. The relay will then automatically re-energize and resume operation.

Key Features
✅ Protects against undervoltage, overvoltage, and power surges
✅ Automatic cut-off and reset for compressor safety
✅ Built-in delay timer for safe restart cycles
