ABB S202-D1 - 1A, 2-Pole, Miniature Circuit Breaker (MCB)

ABB S202-D1 is a compact 1A, 2-pole miniature circuit breaker (MCB) engineered to deliver reliable overcurrent protection where space and performance matter. With a two-pole design, it interrupts both live conductors together, helping prevent fault conditions from propagating and safeguarding both equipment and personnel.

Designed for versatile integration in panelboards, switchboards, and control panels, this MCB from ABB provides precise protection for a range of applications. Its 1A rating makes it an ideal choice for protecting low-current control circuits, instrumentation, and auxiliary loads where sensitive protection is essential, while still delivering robust performance in more demanding environments.

• Current rating: 1A — targeted protection for small or delicate circuits without unnecessary trips.
• Poles: 2-Pole — simultaneous disconnection of both conductors for safer fault clearance.
• Breaker type: Miniature Circuit Breaker (MCB) — compact, dependable overcurrent protection suitable for distribution panels and motor control centers.
• Versatile applications — ideal for industrial facilities, commercial installations, and OEM equipment where dependable protection and safe operation are priorities.
• Key environments — well-suited for use in distribution panels and motor control centers to shield circuits feeding motors, relays, and control systems.

Why choose the ABB S202-D1? It combines ABB’s engineering reliability with a focused 1A, 2-pole configuration that protects critical control circuitry while keeping installation simple in panelboards, switchboards, and control panels. In scenarios where precise current limiting and secure isolation are essential, this MCB delivers predictable, rapid response to overloads and short circuits, helping you minimize downtime and protect downstream equipment.

Practical use cases include small-control circuits in manufacturing lines, auxiliary power feeds in commercial systems, and OEM panel assemblies where a compact yet dependable protection device is required. If you’re upgrading or standardizing protection across multiple panels, the ABB S202-D1 provides a consistent, easy-to-specify solution that aligns with distribution panel and motor control center needs.

Bottom line: For precise 1A protection across two conductors in panelboards, switchboards, and control panels, the ABB S202-D1 2-Pole MCB offers dependable, site-proven performance that supports safe operation in a wide range of industrial, commercial, and OEM applications.
