The MGN60531 is a 3-pole C60N miniature circuit breaker from the Multi9 range, rated 2 A at 50 °C with a D tripping curve (12 x In magnetic release, +/-20 %). Breaking capacity is 20 kA Icu at 240 V AC phase-to-phase (EN/IEC 60947-2), which covers most distribution panels downstream of a 22 kA or lower transformer; at 415 V it drops to 10 kA, and at 440 V to 6 kA — so the voltage at the fault point governs whether this breaker clears without upstream backup. The thermal-magnetic trip unit is fixed — no interchangeable trip blocks. Pollution degree 3, so it's rated for the conductive-dust and humidity environment typical of industrial control panels, not just clean residential load centers.
Integration notes
Tightening torque 2 N·m on the power circuit; strip length 14 mm. The tunnel-type terminals are compatible with standard pin and fork crimp lugs. IP20 finger-safe front, so it can be mounted in a panel with exposed busbars as long as the breaker itself is guarded by the enclosure door or a separate cover.
