The MGN60615 is a 1-pole C60H miniature circuit breaker from the Multi9 range, rated 20 A at 50 °C per EN/IEC 60947-2. The C-curve (magnetic trip at 8.5 x In, +/- 20 %) means it holds brief motor inrush but trips fast on a hard short; it's the standard choice for general-purpose distribution and mixed resistive-inductive loads in a control panel. Breaking capacity is 15 kA Icu at 240 V AC phase-to-neutral, and 24 kA Icu at 60 V DC phase-to-phase. The 24 kA DC rating is unusually high for a 1-pole 20 A MCB; it means this breaker handles battery-bank or rectifier-fed DC bus faults where most residential-grade MCBs would fail.
Snaps onto a 35 mm symmetrical DIN rail, 18 mm wide (2 x 9 mm pitches). That 18 mm width is the standard single-module footprint for a 1-pole MCB — it occupies one slot in a distribution board or enclosure rail. Tunnel terminals accept 1 to 25 mm² rigid or flexible wire; strip 14 mm and torque to 2 N·m.
Suitable for isolation — the contact position indicator shows ON/OFF status visually. Mechanical durability is 20,000 cycles; electrical durability 10,000 cycles at rated load. Ambient operating range is -30 to 70 °C, storage -40 to 80 °C. Earth-leakage protection requires a separate block (not built-in).
