Design and Performance
Multi-Standard Protection in One Device
The iC60N combines circuit protection against short-circuit currents, circuit protection against overload currents, and suitability for industrial isolation per IEC/EN 60947-2 in a single compact device, simplifying circuit protection specification.
Versatile AC and DC Network Compatibility
Designed for use on both AC and DC networks, the A9F74340 offers flexibility for distribution applications spanning conventional AC circuits and DC systems such as those found in renewable energy or battery-backed installations.
C-Curve for General-Purpose Circuits
The C tripping curve provides a magnetic trip threshold suited to general-purpose circuits with moderate inrush currents, such as lighting and standard distribution loads, balancing sensitivity against nuisance tripping.
Clear Visual Fault Indication
A red mechanical indicator on the circuit breaker’s front face provides immediate visual confirmation of a fault trip, helping maintenance personnel quickly identify which breaker has tripped during troubleshooting.
Part of the Widely Deployed Acti9 iC60 Range
As part of the iC60N series spanning a broad range of ratings and curves (B, C, D) from 1 to 63 A across 1P through 4P configurations, the A9F74340 integrates seamlessly into standardized Acti9 distribution board designs.
