ABB S201-K6A 6A 1-Pole 400 V Circuit Breaker

Introducing the ABB S201-K6A 6A 1-Pole 400 V Circuit Breaker — a precise, single-circuit protection device designed to guard your electrical installation against overloads and short circuits. With a 6 A rating and a 400 V capacity, this breaker is built to reliably interrupt fault currents and keep wiring and connected devices safe.

The ABB S201-K6A is a compact, single-pole solution ideal for protecting a dedicated load where current draw stays within a modest range. It helps prevent overheating, reduces the risk of electrical fires, and provides predictable shutdown behavior when faults occur. This makes it well-suited for applications like lighting circuits, control circuits, or small-appliance branches in both residential and light commercial settings.

Key details that matter

• Current rating: 6 A
• Poles: 1
• Voltage rating: 400 V
• Part Number: S201-K6A
• Product type: Circuit breaker for single-circuit protection

Why choose this ABB breaker

• Targeted protection: The 6 A rating provides precise overload protection for loads that don’t require higher current, helping avoid nuisance trips while preserving safety.
• Clear identification: Part Number S201-K6A ensures accurate ordering, stocking, and compatibility in maintenance cycles.
• Trusted reliability: ABB’s engineering delivers consistent trip behavior and durable operation in everyday electrical environments.
• Voltage versatility: A 400 V rating supports modern electrical systems while protecting a single branch circuit from faults.

Use cases and practical benefits

• Protect a dedicated lighting circuit or small equipment load in homes or small offices where the load remains around 6 A.
• Safeguard control circuits within equipment racks or distributed panels that require a defined 6 A protection threshold.
• Serve as a precise replacement breaker in compatible ABB-distributed panels when a single-pole, 6 A device is needed.

Practical outcomes include reduced risk of wiring damage, minimized fire hazards, and clearer, more predictable circuit behavior during fault conditions. By selecting the 6 A rating, you balance protection with reliable operation on normal startup surges.

Shopping notes: Verify panel compatibility and adhere to local electrical codes. If you’re unsure about installation, consult a licensed electrician to ensure safe and compliant setup.
