Tele Voltage Monitoring Relay, 3 Phase, DPDT, DIN Rail

Voltage monitoring 3-phase against N, Voltage failure monitoring, 400V, 2 CO, fixed threshold voltage Us=195,5V

Monitoring relays - ENYA series
Undervoltage monitoring
Supply voltage = measured voltage
2 change over contacts
Width 35 mm
Installation design
Task
The emergency lighting is activated in the event of a mains failure or undervoltage.
Solution
The mains failure is monitored with a E3YF400V02 (three phases). If the voltage falls below 85% of the nominal voltage, the output relay trips and turns the emergency lights on.
Use/value
Detects mains failure
Applications
Emergency Power
Facility Management
Renewable Energy
