The MGN60650 is a C60H miniature circuit breaker from the Multi9 range, rated 4 A at 50 °C with a C-curve (magnetic trip at 8.5 x In ±20 %). At 250 V DC the same pole stack handles 50 kA Icu, so it works in DC bus or battery-string protection without derating to a lower frame. Snaps onto a 35 mm symmetrical DIN rail and occupies 8 x 9 mm pitches (72 mm wide) for the 4-pole version.
Rated operational voltage covers 240/415/440 V AC 50/60 Hz and 250 V DC. Service breaking capacity (Ics) is 50 % of Icu at AC voltages — 15 kA at 240 V, 7.5 kA at 415 V, 5 kA at 440 V — and 100 % at 250 V DC (50 kA). That means after clearing a fault at the rated Ics, the breaker remains functional and can be reclosed; at Icu it clears once and must be replaced. The Multi9 series carries CE marking as standard; UL/CSA listings are typically on the C60H platform but should be verified against the specific catalog number for the destination market. RoHS and REACH declarations are available from the manufacturer's documentation portal.
