How select Q61/1 and Q61/2
Fuses odular irc breakers used, depending specific installation
requirements.5.
Fuses are selected follo s:
- plication safe xiliary pow supply (as diagram 3
and 4), fuses should used.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").
- 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).1 Protection devices Q61/1, Q61/2

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
