The MGN60648 is a Schneider Electric C60H miniature circuit breaker from the Multi9 range, rated 2 A at 50 °C with a C-curve trip characteristic (magnetic tripping at 8.5 x In ±20 %). The 4-pole configuration with 4 protected poles makes it a straight choice for three-phase plus neutral distribution circuits where you need coordinated overcurrent and short-circuit protection on all poles. That is a high-capacity rating for a 2 A frame, so it is sized for installations with substantial upstream fault current, not a lightly braked subpanel. That is a real-world durability figure: if you are coordinating selectivity in a panel where a downstream fault might hit 15 kA, this breaker survives the event and stays in service. At 250 V DC the Icu jumps to 50 kA, which is unusually high for a DC-rated MCB — it handles the arc extinction challenge of DC circuits where there is no natural zero-crossing. Rated operational voltage spans 240 V AC phase-to-phase, 415 V AC phase-to-phase, 440 V AC, and 250 V DC.
The 72 mm width (8 x 9 mm pitches) for a 4-pole breaker is the expected footprint; it occupies four module spaces. The IP20 finger-safe terminals are fine for enclosed distribution boards; no washdown rating here. The toggle control with ON/OFF indication gives a clear visual state for commissioning and troubleshooting.
The C60H series is the high-breaking-capacity variant of the C60 family. If you are auditing an installed base or filling a spare, the Multi9 range is a well-established platform with broad comb-busbar and distribution-block compatibility (top or bottom feed). The separate earth-leakage protection block option means you can add RCD functionality without replacing the breaker.
