Product Information
Full details
The ABB System pro M compact S200 miniature circuit breaker (model 2CDS251001R0025) is designed for residential, commercial, and industrial applications requiring reliable overcurrent protection. Its key benefit lies in its dual tripping mechanisms, offering both overload and short-circuit protection. A potential caveat is its specific B-curve characteristic, which may not be suitable for all inductive loads without careful consideration.

FAQs
What does the 'B' in B2A signify?
The 'B' indicates the tripping characteristic. A B-curve breaker trips between 3 to 5 times its rated current (2A in this case), making it suitable for circuits with low inrush current, such as lighting and socket outlets.
What is the breaking capacity of this model?
This specific model, 2CDS251001R0025, has a breaking capacity of 20 kA at 230/400 V AC.
Can this breaker be used for motor protection?
While it offers short-circuit protection, the B-curve is generally not ideal for motors due to their high starting currents. A C or D curve breaker might be more appropriate depending on the motor characteristics.
What is the difference between thermal and electromechanical tripping?
The delayed thermal tripping mechanism protects against sustained overloads by reacting to heat buildup. The electromechanical tripping mechanism reacts instantly to high fault currents, providing rapid protection against short circuits.
Is this breaker suitable for both AC and DC circuits?
This model is designed for AC circuits. Specialized DC circuit breakers are required for DC applications.
What are the physical dimensions of the breaker?
The breaker has a height of 88 mm. It occupies standard module widths on a DIN rail.
Troubleshooting
Circuit breaker trips frequently
Check for overloaded circuits, faulty appliances, or wiring issues. Ensure the breaker's rated current and tripping characteristic (B-curve) are appropriate for the connected load.
Breaker will not reset after tripping
Verify that the fault condition has been cleared. If the fault persists, there may be internal damage, and the breaker may need replacement.
Visible damage to the breaker
Immediately de-energize the circuit and replace the damaged breaker. Do not attempt to repair a physically damaged device.
Pros and Cons
Pros
- Provides robust protection against both overloads and short circuits.
- Ensures safety and reliability in a wide range of applications.
- Compact form factor saves space in electrical enclosures.
- Compliant with major international safety standards.
- Durable construction with metal and plastic components.
Cons
- The B-curve tripping characteristic might trip prematurely on certain motor start-ups or inductive loads if not properly matched.
- Breaking capacity of 20 kA, while substantial, may not be sufficient for very high fault current scenarios.
- Requires professional installation by a qualified electrician.
Setup, Compatibility & Care
Setup: Installation must be performed by a qualified electrician. The circuit breaker is designed for mounting on a standard DIN rail within an electrical enclosure. Ensure the correct wiring polarity and torque settings as per manufacturer guidelines.
Compatibility: This model is compatible with standard electrical systems adhering to IEC/EN and UL standards. It is suitable for use in residential, commercial, and industrial environments. Ensure compatibility with the specific voltage and current rating of the circuit being protected.
Care: These are maintenance-free devices under normal operating conditions. Regular visual inspection for damage is recommended. Keep the area around the circuit breaker clean and free from dust and debris.
