- application safe xiliary pow supply (as diagram 2), fuses
must selected according the electrical rating the otor operators or
control coils (see technical catalogue relevant irc breaker range).
F line -to -lin voltages low er, odular irc breakers can be
selected follow s:
- application safe auxiliary power supply (as diagrams and 4):
Q61/1 2-pole odular circu breaker In= (S252 C1)
Q61/2: 4-pole odular circu breaker In= (S254 C1)
- application safe auxiliary pow supply (as diagram 2), devices
must selected according the short-circuit current calculated the ain
breakers:
7.
How select Q61/1 and Q61/2
Fuses odular irc breakers used, depending specific installation
requirements.These devices are used protect:
- the ATS010 circuits
- the circu breaker otor operators control coils, they are powered norm al
and emergency lines (see circu diagram ithout safe auxiliary pow supply").
