摘要：
Voltage drop detector adjustable for different nominal current voltages, formed by a functional assembly that comprises an input voltage rectifier stage (DB), after which a cascade sequence of Zener diodes (DZ1, DZ2, DZ3) is arranged, which are connectable selectively in common series or partially, by means of circuit breakers (JP1, JP2), with the power circuit of a relay (RL), so that when the voltage drops below a given value, the relay (RL) is tripped, activating the current cutoff in the installation.
