The MGN60609 is a Schneider Electric C60H miniature circuit breaker from the Multi9 range, rated 2 A with a C-curve trip characteristic. It is a 1-pole unit designed for distribution applications, with a thermal-magnetic trip unit and a breaking capacity of 15 kA Icu at 240 V AC and 24 kA Icu at 60 V DC per EN/IEC 60947-2.
The C-curve means the magnetic trip fires at 8.5 x In (±20%), so it handles moderate inrush from small motors or transformers without nuisance tripping, but still clears fast on a hard short. The 24 kA Icu at 60 V DC is the key number for DC bus or battery-string protection; the 15 kA at 240 V AC covers most single-phase panel feeds.
Snaps onto a 35 mm symmetrical DIN rail, takes 2 x 9 mm pitches (18 mm wide). Tunnel terminals accept 1 to 25 mm² rigid or flexible wire; strip 14 mm and torque to 2 N.m. The ON/OFF toggle and contact position indicator give a quick visual on the state without poking a meter in.
