8.3.7 Connect auxiliary switch AS- AS’
For filter configuration with S option (pre-equipped with
switch, see sections 2.1 to 2.4)
The auxiliary switch is a contact, which indicates state of cir-
cuit breaker. It is closed under normal operation (CB on) and
is open in abnormal condition (CB off). Abnormal condition
can be a short circuit in the trap capacitors, overcurrent in
the trap circuit, too hot ambient temperature or switch-off
status in low load condition (use of motor mechanism to-
gether with the circuit breaker – check relevant section in the
circuit breaker manual
).
For filter configuration with J option (equipped with trap
disconnect jumper for third party switch installation, ,
see sections 2.1 to 2.4)
The AS terminal block is installed, but not connected to any
switch (empty terminal). Customer can connect any auxiliary
switch of an additionally installed third party switch circuit
breaker (NC, NO or other). Customer is fully responsible for
the third party switch installation, wiring and usage accord-
ing to the respective manual.
For wire cross section recommendation see section 3.6.2.
Warning: an engaged auxil-
iary switch not resulting from a
manual or remote controlled open-
ing must lead to immediate load
shutdown and investigation of the
problem.
