The Schneider Electric DOMF01202 is a Domae miniature circuit breaker rated 2 A with a C-curve, 2 poles, and a breaking capacity of Icn 6000 A per IEC 60898-1. It clips onto a DIN rail and uses a thermal-magnetic trip unit to protect final circuits in residential or light commercial panels.
What the ratings mean for fit
The C-curve (magnetic trip 5–10 × In) means it handles moderate inrush from small motors or transformers without nuisance tripping — common for general-purpose socket circuits and lighting. At 2 A it protects a low-current branch, e.g. a control transformer or a small pump. The 6 kA breaking capacity at 230 V AC is the maximum fault current it can safely interrupt. In a domestic or light commercial panel where the prospective short-circuit current stays under 6 kA, this breaker clears the fault without upstream damage. The 2-pole version (2P) switches both line and neutral, with neutral on the left. Thermal-magnetic trip technology means the thermal bimetal handles overloads (slow curve), while the solenoid handles short-circuits (instantaneous). The 18 mm connection pitch between phases matches standard busbar comb systems — check compatibility with your distribution block.
