A9F94463: Supports full Acti9 accessory range:
Multi‑function auxiliary / contatos de alarme
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 >6o
- Critical facilities: industrial, grande comercial, hospital, centro de dados
- Future expansion needed (controle remoto, voltage monitoring, etc.)
- 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
- Somente proteção básica, no complex accessories
- Already installed EA9 panel with matching system parameters
4 Notas de substituição
- Direct interchangeability: Both 4P C63A, DIN‑rail mount – direct replacement.
- Wiring check: A9F94463 neutral position matches EA9AN (esquerda) – no need to reorder wiring.
- Desclassificação: Both derate at >30°C (–1% per °C).
- Compatibilidade de acessórios: Existing EA9 accessories must be replaced with Acti9‑specific versions.
