Arc-fault detection device for final circuits
Rated 16 A with a C-curve trip characteristic, it interrupts fault currents up to 10 kA at 230 V AC, 50 Hz, complying with EN/IEC 62606 and EN/IEC 61009-1/2-1. The white (RAL 9003) housing and top/bottom cable entry keep panel wiring clean and consistent.
Measurement accuracy of ±2 % for voltage and current, ±5 % for power, and the ability to log voltage, active power, current, and power factor make this unit suitable for energy monitoring or fault-event diagnostics — not just protection. The local signalling (ON, OFF, fault trip LED, arc fault diagnostic) gives a visual status without needing to open the panel door. Electrical durability of 20,000 cycles at rated load and mechanical durability of 20,000 cycles align with typical residential/commercial switching duty — expect the unit to outlast the building's fit-out cycle under normal use.
Mounts on DIN rail via the clip-on mechanism. Tightening torque for the terminals is 2 N·m; wire stripping length is 14 mm. Tropicalisation severity B (28-day damp heat test per IEC 60068-2-30) means it handles high-humidity environments without derating. Total power losses of 3.408 W (2.65 W per pole) are low enough that no special ventilation is needed in a standard enclosure. The 73 mm depth fits flush in shallow consumer units.
