Frequently Asked Questions (FAQs) – ABB SB204M-C25 Miniature Circuit Breaker

Your go-to guide for everything you need to know about ABB’s trusted 4P, 25A MCB – System pro M compact SB204M-C25.

1. What is the ABB SB204M-C25 Miniature Circuit Breaker?

The ABB SB204M-C25 is a 4-pole, 25-amp Miniature Circuit Breaker from the SB200M series. It is designed for overload and short-circuit protection with a Type C tripping characteristic. Ideal for residential, commercial, and light industrial installations.

2. What does Type C tripping characteristic mean?

Type C MCBs trip when the current exceeds 5 to 10 times the rated current. This makes them suitable for circuits with moderate inrush currents such as fluorescent lighting and small motor loads.

3. What is the rated breaking capacity of this MCB?

The SB204M-C25 has a rated breaking capacity of 10 kA at 240/415 V AC, which ensures safe interruption of high fault currents without damaging the breaker or wiring.

4. Can I use this MCB in a residential application?

Yes, the SB204M-C25 is compliant with IS/IEC 60898-1 standards and is suitable for residential, commercial, and industrial use, depending on the load type.

5. What is the difference between SB200M and other ABB MCB series?

SB200M series MCBs are part of ABB’s System pro M compact range, designed for current-limiting protection. They feature advanced tripping mechanisms and are compact in size, making them ideal for high-density installations.

6. What are the voltage ratings for this model?

Rated Voltage: 415 V AC
Maximum Operational Voltage: 264 V AC / 60 V DC
Impulse Withstand Voltage: 4 kV

7. What are the physical dimensions of the SB204M-C25?

This MCB has a compact footprint:

Width: 70 mm
Height: 85 mm
Depth: 69 mm
Weight: 0.47 kg
