ABB 2CDS272001R0034 S202M-C3 2P 3A 25kA Type C Miniature Circuit Breaker

The ABB S202M-C3 (SKU: 2CDS272001R0034) is a high-performance 2-pole miniature circuit breaker from the S200M series, rated at 3 A with a Type C trip curve and an exceptional breaking capacity of 25 kA at 230 V AC. Designed for demanding industrial and commercial installations, the S202M-C3 delivers reliable overcurrent and short-circuit protection on standard DIN rail systems, making it the preferred MCB for engineers requiring superior fault-clearing performance in compact modular form.

Technical Specifications

Applications & Use Cases

• Industrial Control Panels: The S202M-C3 is ideally suited for protecting motor feeders, control circuits, and inductive loads where Type C trip characteristics are required to ride through high inrush currents without nuisance tripping.
• Commercial Electrical Installations: Use this 2-pole DIN rail MCB to protect lighting circuits, HVAC equipment, and general distribution boards in commercial buildings requiring robust short-circuit protection.
• Distribution Boards & Switchgear: The S200M series high breaking capacity of 25 kA makes the S202M-C3 suitable for use close to transformer secondaries and bus bars where fault energy levels are elevated.
• Machine Building & OEM Equipment: With its compact modular footprint and superior fault-clearing capability, the S202M-C3 is a standard choice for machine builders specifying IEC-compliant circuit protection.

Frequently Asked Questions

What is the difference between the S202M-C3 and standard S200 series breakers?

The S200M series offers a significantly higher breaking capacity (25 kA at 230 V AC) compared to standard S200 models, making it the preferred choice for installations with higher prospective short-circuit currents.

What does the Type C trip curve mean for the S202M-C3?

A Type C trip curve means the breaker will trip instantaneously on faults between 5× and 10× the rated current (15–30 A for this 3 A unit). This characteristic is ideal for inductive and motor loads that exhibit high inrush currents at startup.

Is the ABB S202M-C3 suitable for DIN rail mounting?

Yes. The S202M-C3 is designed for standard 35 mm DIN rail installation, enabling fast and tool-free mounting in modular distribution boards and control panels.

What is the rated current of the S202M-C3?

The S202M-C3 carries a rated current of 3 A, making it appropriate for low-current branch circuit protection in both industrial and commercial applications.
