2.4.2.2 Outlet sockets for QAX 12-20-30
3-phase units
The outlet sockets application provides the following
outlet sockets and circuit breakers:
X1 .......3-phase outlet socket (400 V Y)
Provides phases L1, L2 and L3, neutral and
earthing.
X2 .......3-phase outlet socket (400 V Y)
Provides phases L1, L2 and L3, neutral and
earthing.
X3 .......1-phase outlet socket (230 V Y)
Provides phase L3, neutral and earthing.
Q1 .......Main circuit breaker and minimum
voltage relay
Interrupts the power supply to X1 when a
short-circuit occurs at the load side or the
overcurrent protection (QAX 12: 20 A,
QAX 20: 32 A, QAX 30: 50 A) is activated
or when the shunt trip is energized. It must
be reset manually after eliminating the
problem.
Q2 .......Circuit breaker for X2
Interrupts the power supply to X2 when a
short-circuit occurs at the load side, or when
the overcurrent protection (QAX 12-20:
16 A, QAX 30: 16 A/32 A) is activated.
When activated, Q2 interrupts the three
phases towards X2. It can be activated again
after eliminating the problem.
Q3 .......Circuit breaker for X3
Interrupts the power supply to X3 when a
short-circuit occurs at the load side, or when
the earth leak detector (30 mA), or when the
overcurrent protection (16 A) is activated.
When activated, Q3 interrupts phase L3 and
the neutral towards X3. It can be activated
again after eliminating the problem.
Circuit breaker Q1 does not only
interrupt the power supply towards
socket X1 but also towards sockets
X2 and X3.
Make sure to switch on circuit
breakers Q1, Q2 and Q3 after
starting the generator when power
supply is done by means of X2 or X3.
