The under-voltage coil YU controls the value of the voltage in the circuit to which it is connected.
The coil opens the circuit-breaker when:
• the power supply voltage of the coil drops to a value in the range 35%… 70% Un
The under-voltage coil YU can in addition be used for the following purposes:
• Release the circuit-breaker remotely using push-buttons of the normally closed type.
• Activate the lock when the circuit-breaker is closed (the closing of the circuit-breaker is
allowed only with the under-voltage coil energized).
NOTE: The power supply of the coil must drawn on the supply side of the circuit-
breaker or from an independent source.
The tables listing the available voltages and the electrical characteristics are provided below:
