FAQs
Is this circuit breaker compatible with residential lighting circuits?
Yes, but ensure the 25A rating is appropriate for your specific circuit load. Lighting circuits often use lower amperages, so verify your electrical design.
Can I install this in a damp environment?
The breaker itself should be housed within a properly rated, ingress-protected (IP) electrical enclosure to prevent moisture contact.
What does the 'B' in S201-B25 stand for?
It refers to the tripping characteristic. B-curve breakers are designed for circuits with low surge currents, typically used for resistive loads.
Does this breaker come with a warranty?
Warranty terms vary by region and distributor; please refer to your purchase documentation or contact ABB directly with your MPN 2CDS251001R0255.
What is the weight of the unit?
The unit weighs approximately 125 grams.
Can this be used for DC applications?
The S200 series is primarily designed for AC voltages. Consult the technical datasheet for specific DC application constraints.
Troubleshooting
Breaker trips immediately upon reset
Indicates a persistent short circuit or ground fault. Disconnect all loads on the circuit and check for damaged wiring or faulty appliances before resetting.
Breaker feels warm to the touch
Check for loose terminal connections causing resistance or verify if the circuit is continuously running near its 25A capacity.
Switch lever won't stay in the 'ON' position
The internal mechanism may be locked or damaged. If the circuit is verified to be clear of faults, the unit may require replacement.
Pros and Cons
Pros
- High reliability with dual-action protection
- Easy to identify switch status via CPI
- Supports space-saving bottom-fitting auxiliary contacts
- Robust construction suitable for industrial environments
- Standardized compact dimensions for easy integration
Cons
- Professional installation strictly required
- Must be matched correctly to circuit load requirements
- Mounting requires standard DIN rail infrastructure
Setup, Compatibility & Care
Installation must always be performed by a licensed professional in accordance with local building codes. The unit mounts onto a standard DIN rail. When installing, ensure that the cables are properly seated in the patented twin terminals and tightened to the manufacturer's torque specifications. The device is designed to be maintenance-free under normal operating conditions. Periodically, however, verify that the terminals remain tight and that there is no dust or debris accumulation inside the distribution board. Always check that the current rating (25A) and the tripping characteristic match the specific requirements of the load being protected.
