The Schneider Electric A9N19887 is an Acti9 DCP Vigi RCBO — a residual current breaker with overcurrent protection, combining a 32 A thermal-magnetic MCB and a 30 mA earth-leakage module in a single 2-pole unit. Integrated 30 mA earth-leakage protection means this single device covers both overcurrent and residual current faults — saves a DIN space vs a separate RCCB + MCB pair, and the trip unit is thermal-magnetic, so no electronics to fail in the overcurrent path. The 30 mA sensitivity is the standard for personal protection against indirect contact in wet or general-purpose circuits.
Tunnel-type terminals top and bottom accept 1...35 mm² rigid or 1...25 mm² flexible — strip 12 mm, torque to 2 N.m. IP20 on the body, IP40 inside a modular enclosure. The white housing and toggle control with ON/OFF/fault-trip local signalling make panel identification straightforward. Rated for isolation (suitability for isolation: yes) with a visible contact position indicator, but not padlockable — so if lockout/tagout is required at the device, plan for a separate locking mechanism upstream. Electrical durability 10,000 cycles, mechanical 20,000 cycles — solid for a distribution-board RCBO.
