The MGN60647 is a C60H miniature circuit breaker from the Multi9 range, rated 1 A at 50 °C per EN/IEC 60947-2. Four protected poles on a 4P frame give you full isolation on a 3-phase + neutral DC or AC circuit — the suitability-for-isolation marking (per EN/IEC 60947-2) means you can use it as a visible-break disconnect for lockout/tagout. That 50 kA DC figure is unusually high for a 1 A frame — it safely interrupts a hard fault on a battery bank or DC bus without cascading upstream.
Snaps onto 35 mm symmetrical DIN rail (EN 60715). Fixed mounting, toggle control, ON/OFF indication on the front. The 4-pole body occupies 8 x 9 mm pitches (72 mm wide). Comb busbar compatible top or bottom — standard for Multi9 distribution boards.
