ABB 2CDS251001R0804 S201-C80 1P 80A 10kA C-Curve Miniature Circuit Breaker

The ABB S201-C80 (SKU: 2CDS251001R0804) is a 1-pole, 80 A miniature circuit breaker (MCB) from the S200 series, designed to provide reliable overcurrent and short-circuit protection for industrial and commercial installations operating at 230/400 V AC. Featuring a C-curve trip characteristic and a rated breaking capacity of 10 kA at 400 V AC per IEC 60898-1, the S201-C80 is ideal for protecting circuits with moderate inrush currents such as lighting, distribution boards, and general-purpose loads.

Frequently Asked Questions

What does the C-curve trip characteristic mean for the S201-C80?

The C-curve trips instantaneously at 5–10× the rated current (400–800 A), making it suitable for loads with moderate inrush currents such as lighting and general distribution circuits.

What is the breaking capacity of the ABB S201-C80?

The S201-C80 has a rated breaking capacity (Icu) of 10 kA at 400 V AC, in accordance with IEC 60898-1.

Is the S201-C80 DIN rail mountable?

Yes, the ABB S200 series MCBs are designed for standard 35 mm DIN rail installation.

What is the difference between the SKU 2CDS251001R0804 and the catalog number S201-C80?

The SKU (2CDS251001R0804) is ABB's internal order reference number, while S201-C80 is the catalog number printed on the device and used in technical documentation, drawings, and BOMs. Both refer to the same product.
