Voltage and phase measuring and monitoring relay
GAVE ELECTRO
Voltage monitoring relay for three phase supply.
Protects against Phase Failure (loss) and Phase Sequence.
Characteristics
• Mounting on symmetrical DIN rail
• Connects when detecting: 3 phases presence
correct phase sequence RST presence
• Trips when detecting: voltage drop > 25%
incorrect phase sequence
• Phase failure is considered when nominal voltage is < 75% rated
• Output changeover relay 8A / 250V AC cos cp = 1
• Operating temperature: -10° to + 60°C
