It is rated 63 A continuous, with 30 mA sensitivity, Type A (AC and pulsating DC fault detection), and 4 poles (4P) for three-phase plus neutral systems. The part clips onto a standard DIN rail, occupies 8 x 9 mm pitch modules (72 mm wide), and is intended for outgoer positions in distribution boards. Rated operational voltage is 380...415 V AC 50/60 Hz, with an insulation voltage of 500 V AC and impulse withstand of 6 kV. Breaking capacity is 1500 A (Idm and Im). The unit is certified to EN/IEC 61008-1, with IP20 (IP40 in modular enclosure) per IEC 60529.
The 63 A rating covers the full load current of a subfeed or a large final circuit — sized for a 3-phase distribution board feeding a workshop or a small commercial floor. The 30 mA sensitivity is the standard for general-purpose shock protection (EN/IEC 61008-1). Type A detection means it trips on sinusoidal AC faults and pulsating DC faults (typical from rectified loads like VFDs, lighting ballasts, or IT equipment). Voltage-independent tripping means the RCCB operates without needing a separate power supply — it uses the fault energy itself to open the contacts, so it works even if the neutral is lost upstream. Instantaneous trip (no intentional delay) is appropriate for circuits where selectivity with downstream RCDs is not required. The 8/20 µs impulse withstand of 250 A means the device tolerates surge currents from lightning or switching transients without nuisance tripping. Padlocking provision allows lockout/tagout during maintenance.
