Acti9 80A 4‑Pole RCCB 300 mA — Schneider Electric Earth-Leakage Isolator 80 A 4P 300 mA

⭐ Key Characteristics

• Rated Current: 80 A

• Poles: 4P (Three-phase + Neutral)

• Residual Current Sensitivity: 300 mA — suitable for main earth-fault and fire risk protection in three-phase systems.

• Type: Typically AC or A type variants available (detects AC or mixed leakage waveforms on earth faults).

• Mounting: DIN-rail modular

• Application Voltage: ~400–415 V AC (three-phase)

🛡️ What It Does

This device detects earth leakage currents of 300 mA or more and disconnects the circuit, helping to:

• Reduce the risk of fire caused by earth faults

• Provide earth leakage protection in industrial and commercial three-phase installations

• Act as a safety disconnect in coordination with other protective devices

📍 Typical Applications

• Three-phase distribution boards

• Commercial & light industrial installations

• Main earth fault protection points

• Workshops, factories & service mains

⚠️ Notes & Installation

• This is an earth leakage isolator (RCD) — it does not provide overload or short-circuit protection on its own; pair it with appropriate MCBs or MCCBs upstream/ downstream.

• Must be installed by a qualified electrician according to local wiring regulations.
