The Schneider Electric MGN60539 is a C60N Multi9 miniature circuit breaker — a 3-pole, 32 A thermal-magnetic MCB with a D trip curve, rated to EN/IEC 60947-2. It breaks 20 kA at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V, which covers most commercial and light industrial distribution panels where fault current stays under those thresholds.
The 20 kA Icu at 240 V gives headroom for high-fault panels; the 10 kA at 415 V still suits most European 400 V distribution. Service breaking capacity (Ics) is 75 % of Icu — 15 kA at 240 V, 7.5 kA at 415 V — meaning it can reclose after a fault at that level.
Snaps onto 35 mm symmetrical DIN rail, fixed mounting. Occupies 6 x 9 mm pitches (54 mm wide), so it takes six module spaces in a distribution board. Tunnel terminals accept 1.5…35 mm² rigid or flexible wire; strip 14 mm and torque to 3.5 N·m. IP20 finger-safe front, suitable for enclosed panels only.
