Panel fit: 25 A C-curve on a 35 mm rail
Mounts on a standard 35 mm DIN rail (EN 60715) and occupies a single module width of 17.5 mm — the 69 mm width listed is the overall envelope including the toggle and terminal housing.
Breaking capacity and fault clearance
For a panel with a prospective short-circuit current (PSCC) above 6 kA, a current-limiting upstream fuse or a higher-rated breaker (e.g., 10 kA or 25 kA) is required ahead of this MCB.
The lifecycle stage is current — ABB continues to manufacture this order code for new installations and replacement stock.
