ABB S202U-K1 1A 2-Pole 240 V Circuit Breaker

The ABB S202U-K1 1A 2-Pole 240 V Circuit Breaker is your compact, dependable solution for protecting low-current electrical circuits. Built by ABB, this 2-pole breaker interrupts both live conductors in a 240 V circuit, delivering reliable overcurrent protection for control panels, lighting, and other sensitive loads. With a precise 1 A rating, it helps keep everyday electronics and automation components safe from overloads without nuisance trips.

Why the ABB S202U-K1 stands out

• Dual-pole design for 240 V protection: By disconnecting both conductors, it provides safer, more robust protection for 240 V circuits and simplifies code-compliant wiring in panel boards.
• Exact 1 A current rating: Ideal for protecting small control circuits, instrumentation, sensors, and other low-current devices where precise protection matters.
• Trusted ABB engineering: Built to deliver consistent performance over time, with a dependable mechanism designed for repeated on/off cycles in demanding environments.
• Clear part identification: Part Number S202U-K1 makes replacement and cross-reference straightforward in maintenance or upgrade projects.

Ideal use cases

• Control panels and automation enclosures requiring tight current protection on 240 V circuits. • Lighting control circuits, small ballast or relay circuits, and other low-amperage 240 V loads. • Retrofits or replacements in residential, commercial, or light industrial settings where a compact, two-pole breaker is needed.

How this breaker helps you operate safely and efficiently

• Enhanced safety: Simultaneous disconnection of both hot lines minimizes shock risk and ensures complete circuit isolation.
• Precise protection: The 1 A rating provides targeted protection for sensitive devices, reducing the chance of unnecessary interruptions in critical systems.
• Simple maintenance: Clear labeling and a standard two-pole format streamline replacement, inspection, and upgrades in consumer or commercial panels.
