About the Schneider Electric Acti9 iC60N A9F74116 Technical Co
A9F74116 is a Schneider Electric miniature circuit breaker from the Acti9 iC60N range, configured as a single-pole device with a rated current of 16 A and a type C tripping characteristic. As a Schneider Electric Acti9 technical component it protects a final circuit against both overload and short circuit: the thermal element responds to sustained overcurrent while the magnetic element trips rapidly on fault current, with the C characteristic placing that instantaneous trip band between five and ten times rated current under IEC 60898-1. That band is the reason a 16 A curve C device is chosen ahead of a curve B equivalent — it rides through the short inrush surge drawn by motors, transformers and switched-mode supplies at start-up instead of nuisance tripping, while still clearing a genuine fault. The single-pole format switches and protects the line conductor only, so neutral arrangements and any requirement for isolation of both poles must be resolved at design stage. Catalogue number A9F74116 is the controlling reference for like-for-like replacement in an existing Acti9 board.

Typical applications
A 16 A single-pole curve C breaker is a standard final-circuit device for socket-outlet rings and radials, fixed appliance supplies, and small motor or fan circuits whose starting current would trouble a lower-threshold characteristic. At 16 A it sits above lighting and control-circuit ratings and is commonly used for power circuits in workshops, plant rooms, containerised facilities and equipment cabinets. It is also fitted as a like-for-like replacement in existing Acti9 distribution boards where a 16 A curve C way has failed or has been re-purposed.
