The MGN60865 is a Schneider Electric C60N miniature circuit-breaker from the Multi9 range, single-pole, C-curve, rated 4 A at 50 °C per EN/IEC 60947-2. It breaks 10 kA Icu at 240 V AC phase-to-neutral and 3 kA Icu at 415 V AC, making it suitable for distribution boards where the fault current stays within those limits. The C-curve magnetic trip triggers at 8.5 x In ±20 %, so it handles moderate inrush from small motors or transformers without nuisance tripping.
Snaps onto 35 mm symmetrical DIN rail, occupies 2 x 9 mm pitches (18 mm wide). Tunnel terminals accept 1…25 mm² rigid or flexible wire; strip 14 mm and torque to 2 N·m. The 73 mm depth leaves clearance for standard gland plates and comb busbars — top or bottom feed is supported.
Rated for isolation with a visible contact-position indicator. Electrical durability is 10,000 cycles; mechanical durability 20,000 cycles. Ambient operating range -30…70 °C, storage -40…80 °C.
