Single pole thermal-magnetic overcurrent circuit breaker with slow
magnetic trip curve, suitable for high inrush currents (up to 12xI
N
).
Suffix -2100 is also available for types 3400 and 3600.
Enquire for further details.
Single pole thermal-magnetic circuit breaker suitable for high ambient
temperatures. The special rating of the circuit breaker allows
resetting at no load in ambient temperatures up to +80
°
C.
Suffix -2350 is also available for types 3400 and 3600.
Enquire for further details.
