Product Description
Designed and manufactured by Siemens AG (Germany), the 5SN4106-7CN miniature circuit breaker provides dependable circuit protection for loads up to 6 amperes. Its C-characteristic tripping curve (5–10× rated current) makes it ideal for general-purpose circuits including:
- Lighting circuits in residential and commercial buildings
- Socket outlet circuits with moderate inrush loads
- Small motor starter circuits (up to ~1kW)
- Control panel and automation cabinet wiring
- Solar PV combiner and junction box protection
With a 10kA breaking capacity per IEC 60898-1, this breaker safely interrupts fault currents up to 10,000 amperes — providing a high safety margin for most installation environments. The compact 1-module design (17.5mm width) maximizes DIN rail space in distribution boards.

Frequently Asked Questions
What does “C-characteristic” mean?
The C-trip curve trips magnetically at 5–10× the rated current (30–60A instantaneous for a 6A breaker). This makes it suitable for most general-purpose loads including resistive loads (lighting, heaters) and loads with moderate inrush currents (small motors, transformers under 1kW).
Can I use this on a 400V three-phase system?
Yes. The 5SN4106-7CN is rated for 230/400V AC. On a 3-phase installation, you would use three individual 1-pole breakers (one per phase) for full 3-phase protection.
What DIN rail does this fit?
Standard 35mm top-hat DIN rail per EN 60715 (TH35 type). This is the most common rail type used worldwide.
What’s the difference between 5SN4 and 5SN6?
The 5SN4 is the standard high-breaking-capacity range (10kA). The 5SN6 offers enhanced features including higher breaking capacity (up to 15kA) and compact 1P+N configurations in a single module.
Is this product RoHS compliant?
All current Siemens 5SN series breakers are fully RoHS and REACH compliant.
What’s the difference between C and D characteristics?
C-characteristic trips at 5–10× In (general purpose). D-characteristic trips at 10–20× In (high inrush loads like large motors, transformers, welding equipment). For most residential and commercial applications, C is the correct choice.
