The Schneider Electric MGN19767 is an Acti9 DCP Vigi residual current breaker with overcurrent protection (RCBO) — a 2-pole device that combines thermal-magnetic overcurrent protection (B-curve, 32 A rated current) with integrated 30 mA earth-leakage protection in a single 36 mm wide module. The B-curve magnetic tripping threshold (3...5 x In) means it responds quickly to moderate overloads, making it a typical choice for general-purpose distribution circuits in residential or light commercial final subcircuits where cable protection and personnel shock protection are both required.
Breaking capacity: 10 kA Icn / Icu at 220...240 V AC, 50 Hz, conforming to EN/IEC 61009-2-1 and EN/IEC 60947-2. Earth-leakage sensitivity: 30 mA, integrated. This is the standard threshold for personnel protection against indirect contact (touch voltage). The RCBO trips when leakage to earth exceeds 30 mA, which is below the threshold for ventricular fibrillation. The 8/20 µs impulse withstand of 250 A means it resists nuisance tripping from lightning surges or switching transients common in industrial environments. IP20 (device) / IP40 (modular enclosure) per IEC 60529. IP20 means finger-safe — no ingress protection against water, so it belongs inside a cabinet or distribution board, not in a wet area. IP40 on the enclosure side means protection against tools and small wires (1 mm) but still no water. For washdown zones, you'd need an IP65-rated enclosure around it.
The tunnel-type terminals accept 1...35 mm² rigid or 1...25 mm² flexible copper; strip length 12 mm, tighten to 2 N.m. That wire range covers most final circuit cable sizes up to 6 mm² (10 AWG) comfortably, and the tunnel terminal is a standard cage clamp — no special tooling. The toggle control gives ON/OFF/fault trip local signalling, and the contact position indicator confirms isolation status. Non-padlockable, so if lockout/tagout is required, you'll need a separate lockable isolator upstream or a padlockable accessory.
