FREOGUARD 30A 220V Voltage Monitoring & Protection Relay ACRTOOLS

ACRTOOLS FREOGUARD 30A 220V Voltage Monitoring & Protection Relay.

Functions:

• Phase loss detection.
• Voltage level monitoring.
• Power supply instability monitoring.
• Overvoltage and undervoltage protection.

The FREOGUARD continuously monitors the incoming supply voltage and protects connected equipment from any voltage abnormality outside the 190–260V operating range.

If the voltage exceeds or falls below these limits, a 3-minute timer starts. If the voltage remains outside the safe operating range after the delay period, the FREOGUARD deactivates the output relay, disconnecting and protecting the connected equipment.

While the output remains switched off, a second delay timer is activated to prevent immediate restarts and protect compressors and other electrical equipment.

In general, the FREOGUARD is a single-phase voltage monitoring relay with integrated automatic monitoring and protection for single-phase electrical applications. It helps prevent costly damage caused by phase loss, unstable power supply, overvoltage, and undervoltage.

Its compact dimensions (9 × 7 × 3.5 cm) make it suitable for installation even in space-limited systems. It can also be connected directly to the main power supply, providing protection for the entire electrical installation.

Features:

• Three LED status indicators:

  • Red: Voltage fault detected – output relay open (Comp OFF).
  • Yellow: Delay timer active.
  • Green: Normal voltage – output relay closed (Comp ON).
• 3-minute Delay-On-Break timer to prevent immediate restarts.
• Automatic voltage monitoring from 190V to 260V.
• 30A output relay.
• Built-in 3-minute restart delay to prevent repeated compressor cycling and protect connected equipment.
