The MGN60891 is a Schneider Electric C60N miniature circuit breaker from the Multi9 range, rated 4 A at 50 °C with a C-curve trip characteristic and three protected poles. Breaking capacity is 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V — numbers that govern selectivity and SCCR coordination in a panel.
Snaps onto 35 mm symmetrical DIN rail — standard for enclosure mounting in panel builds. Occupies 6 x 9 mm pitches (54 mm wide), so it takes three module spaces on the rail. IP20 finger protection per EN/IEC 60947-2, suitable for enclosed panel installation where the front face is accessible. Pollution degree 3 rated — handles conductive pollution typical in industrial control rooms. Electrical durability is 10,000 cycles; mechanical durability 20,000 cycles.
Listed as current-production (active lifecycle stage). The MGN60891 is a standard catalog item in the Multi9 / C60N family, widely specified in distribution boards and subpanels across industrial and commercial sites.
