Schneider Electric Acti9 iC60N A9F74110 Miniature Circuit Breaker, 1P 10A Curve C — BOLTON SKU 55039.
About the Schneider Electric Acti9 iC60N A9F74110 Technical Co
A9F74110 is the 10 A single-pole member of the Schneider Electric Acti9 iC60N miniature circuit breaker family, supplied with a type C tripping characteristic whose instantaneous trip band sits at five to ten times rated current under IEC 60898-1. On this Schneider Electric Acti9 technical component that translates to a magnetic trip threshold of roughly 50 A to 100 A, with the thermal element handling slower overloads below that. The 10 A rating is chosen where the circuit’s continuous load is modest but the connected equipment still draws a brief inrush at switch-on — small transformers, control gear, switched-mode power supplies and compact motors — so a curve B device at the same rating would risk tripping on energisation. Being single-pole, it makes and breaks the line conductor only. Catalogue number A9F74110 identifies the exact rating and characteristic within the range, which matters because iC60N devices of different ratings are physically interchangeable in the board and can only be told apart by their marking.

Typical applications
Ten-amp curve C ways are typically allocated to lighting circuits with electronic drivers or ballasts, control and instrumentation supplies, small fan and pump circuits, and dedicated feeds to equipment cabinets whose steady-state draw is well under the rating but whose start-up surge is short and sharp. The lower rating also allows tighter discrimination against upstream protection than a 16 A device on the same board. In refurbishment work it is fitted where an existing 10 A way must be replaced without altering the circuit design or cable sizing.
