MT66 Combined protector with reclosing: IGA + permanent overvoltage
Referencia: MT66UV80SC10
• Standards: EN50550 / IEC61643-1 / IEC60898-1
• Permanent overvoltage trip threshold:
• 2P: 290V
• 4P: 500V
• Permanent undervoltage trip threshold:
• 2P: 160V
• 4P: 270V
• IGA breaking capacity: 6KA
• Dimensions: 54mm (2P) and 90mm (4P)
• Do not install on lines without neutral
• Principle of operation:
1. It disconnects the line when there is an overvoltage, undervoltage or the input voltage disappears (even when you want to close the circuit breaker manually).
2. It will automatically reconnect the line 3 seconds after the input voltage has been restored to normal.
3. It will delay the disconnection of the power supply for 3 seconds to avoid the "island effect".
• Main applications:
• Electric vehicle charger protection
• Residential and tertiary protection
• Protection against "island effect" in photovoltaics
• Street lighting, industrial refrigeration, LED screens, etc.D58
