1. Product Overview

The ABB 2CDS211001R0104 is a single-pole miniature circuit breaker (MCB) from the ABB SH200 series. It provides protection against overload and short-circuit faults in AC distribution circuits. The breaker features both thermal trip (overload) and electromagnetic trip (short-circuit) mechanisms, allowing fast disconnection of abnormal currents, preventing wiring damage and fire hazards. It is suitable for residential, commercial, and light industrial low-voltage distribution systems.

• High Breaking Capacity – 6 kA interrupting rating suitable for residential and light industrial circuits.

• Wide Operating Temperature – Reliable operation from ‑25 ℃ to +55 ℃.

• International Standards Compliance – Meets IEC/EN 60898‑1 for global low-voltage AC systems.

4. Typical Applications

• End-circuit protection in residential and apartment installations

• Circuit protection for commercial buildings (lighting, sockets)

• Small office distribution boards

• Light industrial assembly lines and terminal equipment protection

• Distribution panels and control cabinet end circuits

• Any low-voltage AC system requiring 10 A overload and short-circuit protection

5. Installation & Usage Notes

• Correct Rating Selection – Ensure breaker rating matches the load to avoid nuisance trips or protection failure.

• DIN Rail Mounting – Secure mounting on standard TH35 rails.

• Proper Terminal Connections – Tighten screws to recommended torque to prevent poor contact and overheating.

• Environmental Considerations – Avoid prolonged exposure to high humidity, dust, or corrosive environments.

• Periodic Maintenance – Inspect appearance, wiring, and trip events for reliable operation.

• Do Not Mix Different Types – Avoid installing different trip characteristic breakers in parallel on the same rail without isolation.
