Technical specifications
The 3VT9 5006AE00 signalling unit is a modular accessory for
the 3VT4 and 3VT5 circuit breakers and collaborates with the
electronic releases 3VT9 5..-6AC00, 3VT9 5..-6AP00 and
3VT9 5..-6AD00.
• It is intended for applications in automated-control systems
• The unit signals reaching a certain current value in a circuit
and the tripping of the circuit breaker by releases (dependent,
independent, undercurrent)
- user has a options to set up (by steps, using a rotary switch)
an amount of current he wishes to indicate if it has been
reached
- the options are 70; 80; 90; 100; 120; 140; 160 or 180%

(refer to the Table below for more details).
• Local indication regarding the state of the circuit breaker and
the protected circuitry is carried out by LED indicators on the
front panel of the unit
• The information on the state of the circuit breaker is transferred
from the release to the signalling unit by means of optical cou-
pling
• Remote indication on the state of the circuit breaker and the
protected circuitry is ensured by a relay, the make and break
contacts of which are pulled into the terminal strip on the unit
- relays to indicate tripping of dependent or undercurrent and
independent releases have storage
- after the storage relay is activated by tripping of a release,
it is necessary to reset the relay using the front panel RESET
switch or by an external push button remotely.
• The supply voltages are presented in the table
• The main power supply and the reset circuit are not concur-
rently conformable with conditions for safe separation of the
circuits
• The external RESET button must be connected using a
screened cable or a twisted wire with maximum resistance of
the loop 100 Ohm.
The signalling unit will not work without power supply!
