6 Installazione & Note sulla selezione
- Precauzioni per l'installazione
Must be mounted on 35mm standard DIN rail, installation depth ≥78.5mm
Terminal suitable for copper conductors: 1.5–35mm²
Neutral must be connected to the designated left terminal – do not reverse.
- Selection recommendations
Total three‑phase load current ≤63A, suitable for C‑curve loads (not heavy motor starting).
For distribution systems with short‑circuit current >6IL, upgrade to higher breaking capacity models (per esempio., Serie Acti9).
Derate at ambient temperature >30°C: current reduced by 1% per °C rise.
Schneider EA9AN4C63 vs Acti9 A9F94463 Full Comparison & Raccomandazione di aggiornamento
A colpo d'occhio: A9F94463 (iC60L series) is superior to EA9AN4C63 in breaking capacity, compactness, accessory expandability, and electrical/mechanical endurance, suitable for higher short‑circuit risk and higher reliability/expandability requirements.
EA9AN4C63 is more economical and meets basic protection for standard residential and light commercial use.

2 Detailed Performance Differences
2.1 Capacità di interruzione: Core Safety Gap
EA9AN4C63: 6IL, suitable for general systems with short‑circuit current ≤6kA.
A9F94463: 15kA elevato potere di interruzione, reliably clears higher short‑circuit currents, reduces arc risk.
Adatto per:
Impianti industriali, large commercial buildings
Distribution circuits near transformers
Systems where short‑circuit current may exceed 6kA
2.2 Design compatto: Better Space Utilization
A9F94463 depth only 44.5mm, greatly reduced from EA9AN4C63 78.5mm.
Vantaggi:
Fits slimmer distribution boards/cabinets
Risparmia spazio di installazione, eases maintenance
Ideal for retrofit projects with limited space
2.3 Endurance & Affidabilità: Longer‑Term Stability
Electrical endurance from 10k → 15k operations; mechanical 20k → 25k.
A9 series uses higher‑grade materials and precision manufacturing for better long‑term stability.
Better vibration and impact resistance for harsh environments.
2.4 Accessory Expandability: Flexible Function Upgrades
EA9AN: Supports only basic auxiliary contacts and shunt trips.
A9F94463: Supports full Acti9 accessory range:
Multi‑function auxiliary / contatti di allarme
Remote‑control shunt trips
Over/undervoltage protection modules
Auto‑reclose accessories
Ti24 interface for PLC/BMS integration
3 Upgrade Decision Guide
Recommended to upgrade to A9F94463 if:
- Calculated short‑circuit current >6IL
- Critical facilities: industriale, large commercial, Ospedale, centro dati
- Future expansion needed (telecomando, voltage monitoring, ecc.)
- Limited panel space requires compact solution
- Higher reliability and longer service life required to reduce maintenance cost
Recommended to keep EA9AN4C63 if:
- Standard residential / small shop loads, short‑circuit ≤6kA
- Budget‑sensitive, cost priority
- Basic protection only, no complex accessories
- Already installed EA9 panel with matching system parameters
4 Note di sostituzione
- Direct interchangeability: Both 4P C63A, DIN‑rail mount – direct replacement.
- Wiring check: A9F94463 neutral position matches EA9AN (left) – no need to reorder wiring.
- Declassamento: Both derate at >30°C (–1% per °C).
- Compatibilità accessori: Existing EA9 accessories must be replaced with Acti9‑specific versions.
