The MGN60519 is a C60N miniature circuit breaker from the Multi9 range, rated 2 A with a D tripping curve, 2 poles, and a 20 kA Icu breaking capacity at 240 V AC. It's a thermal-magnetic MCB built to EN/IEC 60947-2, which means it's rated for distribution duty in industrial control panels — not just residential final circuits. The 73 mm depth and 81 mm height are standard for the C60 footprint, so it slots into an existing Multi9 panel layout without re-spacing.
Breaking capacity and selectivity — the real-world limits
That's the figure a site electrical engineer cares about for selectivity coordination downstream. At 415 V the Icu drops to 10 kA, and at 440 V to 6 kA. For a 2 A D-curve breaker, the 10 kA at 415 V is typical for motor branch circuits on a 400 V supply; the 6 kA at 440 V is the ceiling for a 440 V line-to-line system.
IP20 finger-safe terminals. Mechanical durability 20,000 cycles, electrical 10,000 cycles. The MCB is suitable for isolation — it has a contact position indicator and ON/OFF local signaling. Earth-leakage protection requires a separate block; this is the plain MCB, not an RCBO.
