The Schneider Electric A9F05413 is an Acti9 iC60N miniature circuit breaker rated 13 A with a D tripping curve, 4 poles, and a thermal-magnetic trip unit. It's built for distribution panels where high inrush loads — motor starts, transformer energization, or capacitive banks — demand the D curve's 12 x In magnetic trip threshold. The 36 kA Icu at 12-133 V AC (per IEC 60947-2) gives real fault-clearing headroom on low-voltage secondaries; at 400 V it still holds 10 kA Icu, enough for most European industrial panels.
The D curve (12 x In +/- 20%) means this breaker holds through short-duration current spikes up to roughly 156 A before the magnetic trip fires. The 13 A rating is the continuous thermal current; wire the load at 13 A or below, sized per the terminal range (1-25 mm² rigid, 1-16 mm² flexible). Breaking capacity is dual-rated: 36 kA Icu at 12-133 V AC, 20 kA at 220-240 V, 10 kA at 380-415 V, and 6 kA at 440 V (all per IEC 60947-2). Under IEC 60898-1 it's rated 10 kA Icn at 400 V. The 36 kA figure at low voltage is useful for high-fault locations near transformers; the 6 kA at 440 V still covers standard distribution. Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (residential/commercial), so it qualifies for both IEC 61439 switchgear assemblies and domestic consumer units.
Snaps onto standard DIN rail. 72 mm wide (8 x 9 mm pitches), 91 mm tall, 78.5 mm deep. The toggle actuator and trip indicator give local status at a glance. IP20 finger-safe terminals for enclosed panel use.
