Welcome to our FAQ section dedicated to the ABB SB204M-C10 miniature circuit breaker—your go-to resource for everything from technical specs to real-world applications. Whether you’re an electrical contractor, panel builder, or DIY enthusiast, these answers will help you understand why this breaker is trusted across residential, commercial, and light-industrial installations.
1. What is the ABB SB204M-C10 MCB?
The SB204M-C10 is a 4-pole miniature circuit breaker from ABB’s System pro M compact series. It features a C-type tripping characteristic for balanced overload and short-circuit protection and is rated for 10 A nominal current with a 10 kA breaking capacity.
2. What does “C-type tripping characteristic” mean?
C-type breakers trip between 5 × In and 10 × In (i.e., 50 A–100 A for a 10 A breaker), making them ideal for mixed resistive and inductive loads—think lighting circuits, small motors, and general distribution panels.
3. Which standards and certifications does it comply with?
The SB204M-C10 fully meets IS/IEC 60898-1 requirements for residential, commercial, and industrial use. It carries the CE mark and is tested to withstand impulse voltages up to 4 kV (Uimp) in overvoltage category III.
4. What are its key electrical specifications?
Impulse Withstand Voltage (Uimp): 4 kV
Rated Current (In): 10 A
Breaking Capacity (Ics): 10 kA at 240/415 V AC
Operational Voltage: up to 264 V AC / 60 V DC
Frequency: 50 Hz
5. What are the physical dimensions and installation details?
Terminal Capacity: rigid up to 25 mm², flexible up to 16 mm²
Width × Height × Depth: 70 × 85 × 69 mm
Weight: 0.47 kg
Mounting: Standard DIN-rail
6. In which environments can I use this MCB?
Thanks to its IP40 protection when enclosed, this breaker works well in:
Solar PV distribution boxes
Residential switchboards
Office and commercial panels
Light-industrial control panels
7. How do I request a quote or place an order?
Simply visit ABB SB204M-C2 MCB – Shansen Enterprises—and click the WhatsApp icon on the SB204M-C10 listing. Send us your load details and quantity, and we’ll reply with pricing and delivery timelines.
8. How does the SB204M-C10 differ from B- or D-type breakers?
D-type: Slower trip (10–20 × In), suited for heavy inductive loads like large motors.
B-type: Trips faster (3–5 × In), best for purely resistive loads (lighting, heating).
C-type: Balanced (5–10 × In), versatile for mixed loads.
9. What maintenance is required?
Minimal—periodic visual inspections for dust or corrosion and a manual toggle test every six months ensure reliable operation. Always isolate the incoming supply before performing any checks.
10. Who can I contact for technical support?
