It's rated 25 A continuous, with a 30 mA earth-leakage sensitivity and a 230 V AC operational voltage, so it catches both series and parallel arc faults plus ground leaks in one unit. The arc-fault detection thresholds trip at 275 V (+/- 5 V), and the earth-leakage protection is Type A-SI (Super Immunised), meaning it resists nuisance tripping from high-frequency inverter noise or transient surges out here in the grease.
Mounts via clip-on onto a DIN rail (35 mm per EN 60715). The 1P+N configuration has the neutral on the left. Termination uses tunnel-type terminals: 1 to 16 mm² rigid or 1 to 10 mm² flexible, with a tightening torque of 2 N.m and a 14 mm strip length.
Compliance standards include EN/IEC 62606 (arc-fault detection devices), EN/IEC 61009-1, and EN/IEC 61009-2-1 (residual current breakers with overcurrent protection). It carries IMQ quality mark. The unit is tropicalised to Severity B per IEC 60068-2-30 for 28 days, so it holds up in humid environments — a real plus for a lube-tech route where condensation on the panel door is the norm.
Electrical durability is rated at 10,000 cycles above 25 A and 20,000 cycles at or below 25 A; mechanical durability is 20,000 cycles. The local signalling includes ON/OFF status, a fault-trip LED, and an arc-fault diagnostic LED, so a field tech can read the fault type without a meter. The device also records date-and-time stamps and maintenance indicators, compatible with EcoStruxure Panel Server concentrators for remote monitoring.
