Product details

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.

Frequently asked questions

What is the difference between 2CCS451001R0254 and 2CCS451001R0253?

The two order codes differ in rated current: 2CCS451001R0254 is a 25 A breaker, while 2CCS451001R0253 is a 20 A breaker. Both are 1-pole, C-curve, 440 V, 6 kA, DIN rail mount — the only parametric difference is the current rating.
