> SC49N Series miniature circuit breaker
Standard: IEC60898

> Technical Data
Number of poles:1,2,3,4,1+N,3+N Input terminals:
Nominal current In(A) =Clip terminals(with barrier layer),snap-locked
1,2,3,4,6,8,10,13,16,20,25,32,40,50,63 against the worse input of a conductor
Characteristics: The input and output can be interchanged
B The short-circuit release is to be set up to 3 In They enable more conductors as well as
through 5 In.It serves especially for protection of cir- interconnecting strips to be connected

Nominal voltage: For better distinction among circuits in the
1P (single-pole)~230/400V 50/60Hz switchboards,we supply also miniature circuit
3P (three-pole)~400V 50/60Hz breaker with distinction of nominal currents by
Rupturing capacity: means of colored levers corresponding to the col-

operational rupturing capacity) 0.2A-1.6A(Black)
Protection:IP40 for a sole MCB with its design, 2A(Pink)
it protects against a hazardous finger or instrument 4A(Brown)
touch as well as against very small foreign objects; 6A(Green)
It is without any protection against water leakage 8A(Light green)

onto the falt surface by means of screws.
Removal form the DIN strip:
By means of an unique auxiliary snap
mechanism, the MCB’s can be removed even from
a row of devices mutually interconnected by a
forked or reed rack strip without necessity to dis-
