The Schneider Electric MGN60881 is a C60N Multi9 miniature circuit breaker — 2-pole, C-curve, rated 16 A at 50 °C per EN/IEC 60947-2. It breaks up to 20 kA Icu at 240 V AC phase-to-phase, with a service breaking capacity (Ics) of 15 kA at the same voltage, so it clears faults at full rated interrupting capacity and still leaves the breaker usable downstream. The C-curve magnetic trip fires at 8.5 x In ±20 %, meaning it holds motor inrush and transformer energization without nuisance tripping while still clearing moderate short circuits fast.
Snaps onto a 35 mm symmetrical DIN rail and occupies 4 x 9 mm pitches — 36 mm wide. The 73 mm depth leaves clearance behind a standard 80 mm deep enclosure backplate. Tunnel terminals accept 1…25 mm² rigid or flexible copper, torqued to 2 N·m. IP20 finger-safe terminals suit enclosed distribution boards; not rated for wet or dusty environments.
