It protects a final subcircuit against arc faults, earth leakage, overload, and short circuit, all in one 36 mm wide clip-on DIN-rail package. The 6 kA breaking capacity at 240 V AC 50 Hz (per AS/NZS 61009.1) is sized for residential and light commercial distribution boards where the prospective fault current stays under that level. Integrated earth-leakage protection means you don't need a separate RCCB upstream for the protected circuit — the VigiARC combines both functions. Trip technology is thermal-magnetic for the overcurrent side, with a separate electronic sensing circuit for arc-fault detection.
Designed to EN/IEC 62606 (arc-fault detection devices) and AS/NZS 61009.1 (RCBOs). It carries the RCM quality label for the Australian and New Zealand markets. Limitation class 3 per AS/NZS 61009.1 means it limits let-through energy in a fault event, reducing stress on downstream wiring. Pollution degree 2 (suitable for normal indoor environments with non-conductive contamination), overvoltage category III (distribution-board level), and IP20 finger-safe terminals. Tropicalisation severity B per IEC 60068-2-30 means it withstands 28 days of damp heat cycling — relevant for coastal or high-humidity installations.
Neutral is on the left, cable entry from top and bottom. Local signalling shows ON, OFF, and fault-trip status — useful for quick troubleshooting without a meter. Electrical and mechanical durability both rated at 20,000 cycles, which is typical for a domestic-grade MCB/RCBO.
