The 20 A rated current at 30 °C sets the continuous thermal capacity for resistive and mixed loads; the C-curve (5–10 x In) means the magnetic trip releases between 100 A and 200 A for short-circuit faults, which is the standard choice for general-purpose distribution circuits feeding socket outlets and small appliances. The 300 mA earth-leakage sensitivity is a delayed-action or high-threshold RCD intended for protection against fire risk from earth faults, not direct personal shock protection (which requires 30 mA or lower). This makes the A9N19645 suitable for circuits supplying fixed equipment where 30 mA nuisance tripping is a concern — think lighting banks, air-handling units, or commercial kitchen appliances — while still providing ground-fault detection. The integrated earth-leakage protection is instantaneous (no intentional time delay), so it will coordinate with upstream time-delayed S-type RCDs in a selective scheme. The thermal-magnetic trip unit is the standard dual-element design: a bimetal strip handles overload protection (inverse time curve), and a solenoid coil handles short-circuit protection (instantaneous above the C-curve threshold). The 20,000-cycle electrical durability and matching mechanical durability (conforming to IEC 61009) reflect a solidly built device rated for typical switching duty in distribution — not a high-cycling contactor application, but fine for the occasional manual isolation or fault interruption over its service life. The 1P+N configuration (neutral left, phase right) is the standard arrangement for single-phase outgoing circuits in European-style distribution boards. Tunnel-type terminals accept up to 10 mm² flexible or 16 mm² rigid cable, which covers the full range of conductor sizes for a 20 A circuit. Embedding depth of 72 mm fits standard shallow enclosures. The toggle control provides local ON/OFF indication and manual switching; the contact position indicator confirms the state of the main contacts independently of the toggle mechanism — useful for lockout/tagout verification during panel maintenance. Tropicalisation level 2 conforming to EN 61009 indicates the device is treated to resist humidity and fungal growth — relevant for installations in coastal or high-humidity environments. Certified to EN/IEC 61009-1 and EN/IEC 61009-2-1, the harmonized standards for RCBOs in Europe. Limitation class 3 (energy-limiting performance) means the device restricts the let-through energy during a short-circuit fault, reducing stress on downstream wiring and connected equipment.","metaTitle":"Schneider Electric A9N19645 Acti9 DPN Vigi RCBO, 20A C-Curve","metaDescription":"Schneider Electric A9N19645 Acti9 DPN Vigi RCBO. 20A rated current, C-curve, 300mA earth leakage, 6kA breaking capacity.
