What this MCB does in the panel
The Schneider Electric C60H3P50AC is a 3-pole C60H miniature circuit breaker rated 50 A at 30 °C, with a C-curve trip characteristic (magnetic tripping between 5 and 10 times In). At 230…240 V AC the C60H3P50AC interrupts 30 kA; at 400…415 V AC it handles 15 kA; at its rated operational voltage of 440 V AC it breaks 10 kA. All figures are Icu per IEC 60947-2, so the standard certifies the breaker can make and break a fault once at that level and still be serviceable. The thermal-magnetic trip unit handles overloads via a bimetal strip (thermal) and short-circuits via a solenoid (magnetic). The C-curve means the magnetic trip fires between 5× and 10× In — 250 A to 500 A for this 50 A unit — which suits lighting, distribution, and general-purpose loads where inrush is moderate but not as high as motor-start.
The ON/OFF toggle gives local indication, and a contact position indicator confirms the main contacts are open — IEC 60947-2 certified for isolation when the handle is in the OFF position.
Tropicalisation level 2 per IEC 60068-1, limitation class 3 per IEC 60947-2. Operating temperature range -25…60 °C, storage -40…70 °C. Relative humidity 95% at 55 °C. Altitude limit 2000 m. The MCB carries IEC 60947-2 certification for the breaking capacity and isolation claims listed above.
