⚡ Acti 9 Indication & Tripping Auxiliaries

Acti 9 indication and tripping auxiliaries are modular add‑on devices that provide remote status indication, fault signalling, and remote tripping for Acti 9 MCBs, RCCBs, and RCBOs.
They enhance monitoring, control, and safety in commercial and industrial panels.


🟦 What These Auxiliaries Do

  • Indicate breaker status — ON/OFF/TRIPPED signals
  • Provide remote signalling to BMS/SCADA
  • Enable remote tripping via shunt or undervoltage release
  • Improve safety & diagnostics with clear fault outputs

🟧 Key Auxiliary Types

  • OF Auxiliary Contact — open/closed position indication
  • SD Fault‑Signal Contact — trips only on fault (overload/short‑circuit)
  • OF+SD Combined — position + fault indication in one module
  • MX Shunt Trip — remote tripping via external command
  • MN Undervoltage Release — trips when supply voltage drops or is cut
  • MNx Emergency‑Stop Variant — safety‑rated undervoltage release

🟨 Typical Applications

  • BMS/SCADA integration — remote monitoring of breaker status
  • Safety interlocking — emergency‑stop circuits, machine safety
  • Load shedding & control — remote trip for demand management
  • Fault diagnostics — identify overload vs manual OFF

🟩 Position in the Acti 9 Ecosystem

  • MCBs (iC60) — overcurrent protection
  • RCCBs (iID) — leakage protection
  • RCBOs (iDPN Vigi / Vigi iC60) — combined protection
  • Auxiliaries — monitoring, signalling, remote control

Auxiliaries = the intelligence layer that adds monitoring and control to Acti 9 breakers.


⭐ One‑line summary

Acti 9 indication and tripping auxiliaries provide remote status, fault signalling, and remote‑trip capability, enhancing monitoring, safety, and automation in modern electrical panels.
