ABB S281K2A - 2A, 1-Pole, Circuit Breaker

Introducing ABB S281K2A — a compact 2A, 1-Pole circuit breaker designed to deliver precise overcurrent protection where space and reliability matter most. Built for industrial, commercial, and OEM environments, this device safeguards distribution and control systems with consistent performance you can trust.

Precise protection for compact panel layouts

The S281K2A is rated for 2 amps and configured as a single pole, making it ideal for protecting individual, low-current branches within panelboards, switchboards, and control panels. Its 1-pole design reduces wiring complexity and footprint while maintaining robust safety margins for sensitive loads.

Where it shines

• Industrial, commercial, and OEM applications: Perfect for distribution panels and motor control centers that demand dependable overcurrent protection without sacrificing space.
• Control and instrumentation circuits: Protects signaling, sensing, and small-motor feeds that require precise, low-amperage protection.
• Easy integration: Suits standard ABB protection schemes and easily fits into common panel configurations.

Why choose ABB S281K2A

From a trusted global electrical safety brand, this breaker combines durability with predictable performance in challenging environments. The 2A rating delivers targeted protection for circuits that don’t need higher current capacity, helping minimize nuisance trips while shielding equipment from overcurrent events.

Practical considerations

• Compatibility: Designed for panelboards, switchboards, and control panels, and particularly suitable for distribution panels and motor control centers.
• Reliability: ABB's engineering delivers consistent trip characteristics and long service life in industrial settings.
