Independent of the supply voltage
Function
b
b
Trips the device with which it is combined when its input voltage decreases
(between 70 % and 35 % Un). Prevents device closing again until its input voltage is
restored
b
b
Tripping of the associated device by
opening of the control circuit
(e.g. push-button, dry contact)
b
b
Not tripping on transient
voltage dip
(up to 0.2 s)
b
b
A drop in the supply voltage does not
trip the associated device
b
b
A locking push-button control allows
the circuit protected (e.g. machine
control) to be placed in safety
configuration

Insensitive to control circuit voltage
variation to increase service continuity
Important: Before any servicing
operation switch off the mains power
supply (voltage presence at terminals
