The Schneider Electric MGN25086 is a C60H miniature circuit breaker from the Multi9 range, rated 16 A at 50 °C with a D curve and 1-pole construction. This thermal-magnetic MCB is designed for distribution applications where high inrush currents — motor starting, transformer energization, or lighting banks — demand a D-curve magnetic trip set at 12 x In ± 20 %.
For a 415 V AC phase-to-neutral supply, Icu drops to 4 kA and Ics to 2 kA. That matters when you're coordinating downstream protection in a panel where available fault current exceeds the lower rating — you need to verify the fault level at the breaker's location against these numbers. The D curve (12 x In magnetic trip) means the breaker holds through short-duration current spikes up to roughly 192 A before the solenoid trips instantaneously. Rated operational voltage is 240 V AC phase-to-neutral, 50/60 Hz. This is a 1-pole (1P) device protecting a single phase.
Standards, approvals, and isolation capability
It carries an IP20 finger-safe terminal enclosure once installed. It is marked suitable for isolation per EN/IEC 60947-2, with a clear contact position indicator (ON/OFF) on the toggle. That lets you use it as a visible-break disconnect for local isolation of a circuit during maintenance — no separate isolator needed.
