The Schneider Electric A9P54706 is an Acti9 iC40N miniature circuit breaker rated 6 A with a C-curve, meaning its magnetic trip operates between 5 and 10 times the rated current (5–10 x In per EN/IEC 60898-1, and 8 x In ±20 % per EN/IEC 60947-2). The 3P + N configuration protects three phases and switches the neutral, with the neutral pole on the left side of the unit. Breaking capacity is rated at 10 kA Icu at 400 V AC per EN/IEC 60947-2 (industrial standard) and 6000 A Icn at 400 V AC per EN/IEC 60898-1 (domestic/commercial standard). The thermal-magnetic trip unit combines a bimetal strip for overload protection and a solenoid for short-circuit response. Rated for 20000 electrical and 20000 mechanical cycles, it matches the endurance expected for a distribution MCB in a panel that sees regular switching.
Where it goes — panel integration
The 54 mm width occupies 6 x 9 mm pitches, fitting a standard 6-module position in a consumer unit or distribution board. Tunnel-type terminals accept 1–16 mm² rigid or 1–10 mm² flexible conductors; tightening torque is 2 N.m. IP20 rated on the front (finger-safe), IP40 inside the modular enclosure — suitable for dry indoor panels, not washdown environments. The toggle control provides ON/OFF indication plus a separate trip indicator, so a tripped breaker is visually distinct from one manually switched off. Earth-leakage protection requires a separate Vigi block — this MCB alone does not include RCD functionality.
Approvals include IMQ quality label and compliance with EN/IEC 60898-1 and EN/IEC 60947-2. The dual-standard certification means the breaker carries both the domestic/commercial MCB standard and the industrial circuit-breaker standard, simplifying specification across different installation types.
