Communication System Manual
Hardware:
-Communication-capable circuit-breaker 3WN6 (no. 1): Overcurrent releases D, E/F, H, J/K, N or
P (no. 1a) are communication-capable when fitted with "additional functions 2". (no. 1b). Unlike a
standard 3WN6, a communication-capable 3WN6 circuit-breaker has a communication module (no.
1c). When additional measurement functions are required (e.g. voltage, frequency, power), a
communication module with measurement functions (no. 1d) must be ordered instead of the simple
communication module. (Please refer to section 3.2, page 28 and section 3.1.1, page 37 for a
description of the functionality of the overcurrent release when combined with a communication
module/communication module with measurement functions.)

-Order number:
- The type of overcurrent release ("D"..."P") can be determined from position 10 of the circuit-breaker
order number; enter a "7" in the eighth position of the order number if the circuit-breaker is to be
fitted with "additional functions 2".
- The order number supplement for the communication module is "Z=F01".
- The order number supplement for the communication module with measurement functions is
"Z=F05" instead of "Z=F01".
Example: For a draw-out circuit-breaker, complete with guide frame with overcurrent release "P",
"additional functions 2" and a communication module with measurement functions, the order
number is 3WN6 ......-7.P....-....-Z with Z=F05 +...
Note 1: If the draw-out circuit-breaker and guide frame are ordered separately, 2 order numbers are
required. In the case of a draw-out circuit-breaker without a guide frame, the sixth position of the order
number is "7":
Circuit-breaker order number:
Frame order number:
Note 2: The position signaling switches cannot be ordered separately with communication-capable
draw-out circuit-breakers. They are included in the scope of supply and are located on the position
display unit (bottom right) of the circuit-breaker.
Note 3: In order to remotely close a circuit-breaker via PROFIBUS, the circuit-breaker must be fitted with a
motorized operating mechanism and closing solenoid (Y1). To remotely open a 3WN circuit-breaker via
PROFIBUS, the circuit-breaker must be fitted with a shunt release of the type F1 or F2. The possible
switching commands are illustrated in Fig. 5, page 32 and Fig. 6, page 32, Step 2.
- One DP/3WN6 interface module for each 3WN6 circuit-breaker (no. 2).
Order number:
- A connecting cable from the SUB-D socket on the DP/3WN6 interface module to the SUB-D
socket of the 3WN circuit-breaker (no. 2a). This cable is a standard 9-pole cable (1:1 connection)
with a length of 3m and is supplied with the interface.
- Connection from the "PROFIBUS-DP" terminal of the DP/3WN6 interface module to PROFIBUS-
DP (no. 3).
Order number:
- 24 V DC voltage supply (in acc. with DIN 19240; no. 4).
