Product details

The 2CCS451001R0064: Rated 6 A with C-curve tripping characteristics, this ABB MCB is designed for moderate inrush loads — think lighting circuits, general-purpose socket outlets, and control transformers. The C-curve trips at 5–10× the rated current, so a 6 A unit holds through a motor start surge up to roughly 60 A before opening.

It remains a valid choice for both new designs and replacement stock.

DIN Rail fit and panel clearance

The 1-pole body measures 69 mm wide, 89 mm tall, and 94.5 mm deep — the depth is the key dimension for enclosure clearance behind the DIN rail.

Frequently asked questions

Is ABB 2CCS451001R0064 a suitable replacement for a 6A C-curve MCB?

Yes, it is a direct 1:1 replacement for any standard 6 A C-curve MCB of the same pole count and breaking capacity. The 6 kA breaking capacity matches most domestic and light commercial panel ratings.

Can ABB 2CCS451001R0064 be used for motor protection?

Not as a primary motor-protective device. The C-curve is designed for moderate inrush, but motor-start currents can exceed the magnetic trip threshold (5–10× In) for longer than the MCB's instantaneous trip delay allows. Use a motor-protective circuit breaker (MPCB) for dedicated motor circuits.

What is the difference between B and C curve MCB?

A B-curve MCB trips at 3–5× rated current, suited for resistive loads with low inrush (heating, incandescent lighting). A C-curve trips at 5–10× rated current, handling moderate inrush from small motors, fluorescent ballasts, and transformers. The 2CCS451001R0064 is C-curve.
