What this 2-pole C-curve MCB does on the rail
Breaking capacity is rated 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. That 15 kA figure under the industrial standard gives you headroom for higher fault-current panels — the EN 60898 rating covers the residential/commercial side, while the IEC 60947-2 rating is what you use for industrial coordination studies. On the DC side, it's rated 60 V maximum, so it handles control-circuit protection and small DC bus feeds within that voltage ceiling.
Dimensions: 36 mm wide, 70 mm deep, 121 mm tall. The 70 mm installation depth matches standard DIN-rail enclosures; no extra clearance needed behind the rail. That -40 °C low end is unusual for a standard MCB — it's specified for cold storage, outdoor cabinets, or unheated enclosures in northern climates. The 75 °C high end covers most industrial panel internal temperatures without derating. Protection class: IP20 with connected conductors, IP40 in the handle range.
Material compliance and terminal details
Vibration resistance: 50 m/s² at 25 to 150 Hz and 60 m/s² at 35 Hz (4 seconds). This covers most industrial machinery and conveyor applications without needing additional clamping.
