Product Information
Full details
The ABB System pro M compact S200M Miniature Circuit Breaker (MCB) is designed for reliable electrical circuit protection in residential, commercial, and industrial settings. It offers superior current-limiting capabilities with dual tripping mechanisms for both overload and short-circuit protection. While highly versatile and compliant with international standards, users should ensure proper understanding of its tripping characteristics (B, C, D, K, Z) for optimal application.

FAQs
What is the difference between tripping characteristics B, C, and D?
Tripping characteristics define the range of current at which the breaker's electromechanical trip mechanism operates. Type B trips between 3-5 times the rated current, suitable for resistive loads. Type C trips between 5-10 times, good for loads with moderate inrush currents (e.g., lights, outlets). Type D trips between 10-20 times, designed for high inrush currents (e.g., motors, transformers).
What is the breaking capacity (kA)?
The breaking capacity (e.g., 10 kA) indicates the maximum fault current the circuit breaker can safely interrupt without being damaged. A higher breaking capacity provides greater protection in systems with higher potential fault levels.
Can I use this breaker for DC circuits?
Yes, the S200M series has a rated DC voltage of 125V, allowing for use in certain DC applications. However, always ensure the DC voltage and current requirements of the circuit are within the breaker's specifications.
How do I determine the correct rated current (ampere) for my application?
The rated current should be selected based on the continuous current draw of the circuit and the rating of the protected wire. It should be higher than the normal operating current but low enough to protect the wiring from overheating in case of an overload.
What does 'current limiting' mean?
A current-limiting circuit breaker significantly reduces the let-through energy during a short circuit. It interrupts the fault current very rapidly, limiting the peak current and the total energy that flows, thereby minimizing damage to the electrical system and connected equipment.
Can I mount auxiliary contacts on this breaker?
Yes, bottom-fitting auxiliary contacts can be mounted on the S200M series to save space. These are typically used for signaling purposes (e.g., indicating breaker status to a control system).
Troubleshooting
Breaker trips unexpectedly during normal operation.
Check for overload conditions. Verify the connected load does not exceed the breaker's rated current. Inspect wiring for any signs of damage or short circuits. Consider if the tripping characteristic is appropriate for the load's inrush current.
Breaker will not reset after tripping.
Ensure the fault condition that caused the trip has been cleared. If the breaker has tripped due to a short circuit, a thorough inspection of the circuit and connected equipment is necessary. If the problem persists, the breaker may be faulty and require replacement.
Breaker feels warm to the touch during operation.
Slight warmth may be normal under load. However, if it is excessively hot, check terminal connections for tightness and ensure the wire gauge is adequate. Overloading or a developing internal fault could also be the cause. Consult a qualified electrician.
Pros and Cons
Pros
- Provides robust protection against both overloads and short circuits.
- High breaking capacity ensures safety even with significant fault currents.
- Wide range of configurations and characteristics allows for tailored system design.
- Compliant with major international safety standards.
- Compact design with optional space-saving accessories.
Cons
- Requires specific knowledge of tripping characteristics (B, C, D, K, Z) for correct selection.
- DC voltage rating (125V) may limit its use in certain high-voltage DC applications.
- Installation requires adherence to electrical safety codes and professional expertise.
Setup, Compatibility & Care
Setup: The S200M series MCBs are designed for DIN rail mounting. Ensure the circuit breaker is switched off (in the 'O' position) before installation. Terminals should be tightened to the specified torque. Use appropriate wiring gauges for the rated current.
Compatibility: This MCB is compatible with other ABB System M products and standard DIN rail mounting systems. It complies with IEC/EN 60898-1 and IEC/EN 609 47-2 standards. Ensure the selected tripping characteristic (B, C, D, K, Z) and rated current match the protected circuit's requirements.
Care: Regular inspection of the installation is recommended. Keep the unit clean and free from dust and moisture. Ensure ventilation around the breaker is adequate. No user-serviceable parts are inside; maintenance should only be performed by qualified electricians.
