18/86 IZM circuit-breakers, IN switch-disconnectors
IZM26 tripping characteristics
2010 CA08103002Z-EN
L protection: IEC-C extreme inverse tripping, and S protection: flat characteristic curve
See Notes 3, 7, 8, 9, 23, 25, 28, 29.
IZM26…P... Tripping characteristics for trip units with power measurement
Non-delayed short-circuit protection (I)
I-protection: Adjustable
See Notes 1, 4, 5, 6, 7, 11, 12.
E Set values for short-time delayed short-circuit protection
I-protection: For high short-circuit currents
A Set values for overload protection
C Minimum total opening delay
I Available set values for short-time delayed short-circuit protection Isd
J Short-circuit release for very high currents
S Long delay time at 14 × Ir
F Set values for short-time delayed short-circuit protection with flat
characteristic curve
G The end of the characteristic curve is determined by the type of application
and the switching capacity of the selected switch.
