The ABB S201M-B6 is a 1-pole miniature circuit breaker from the S200M series, rated 6 A with a Trip Curve B characteristic. Curve B trips between 3 and 5 times rated current (18–30 A), making it the right choice for resistive or lightly inductive loads where inrush is low — think lighting circuits, control transformers, or general-purpose power distribution in a panel. The 6 kA interrupting rating at 277 VAC (10 kA at 60 VDC) tells you it can safely clear a fault up to that level without welding contacts or cascading damage upstream — a standard residential and light commercial SCCR for branch-circuit protection. The 1-pole footprint leaves room for multi-pole assemblies when you need shared-trip protection across phases.

Frequently asked questions
Where can I buy the S201M-B6 and get a price?
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm current availability and pricing — no stock count or price figure is published here.
What does the 6 A rating mean for my circuit?
The 6 A rating is the continuous current the breaker carries without tripping under normal conditions. For a Trip Curve B breaker, magnetic trip occurs between 18 A and 30 A (3–5× In), so it protects wiring and loads against short circuits while tolerating the modest inrush of resistive loads like heaters or incandescent lighting.
What is the interrupting capacity of the S201M-B6?
The S201M-B6 has a 6 kA interrupting rating at 277 VAC and a 10 kA rating at 60 VDC. This means it can safely interrupt a fault current up to those levels without failing — adequate for most residential and light commercial branch circuits.
