ABB S201-C50 - 1-Pole, Miniature Circuit Breaker (MCB)

The ABB S201-C50 is a compact, single-pole miniature circuit breaker (MCB) engineered for dependable overcurrent protection in demanding electrical environments. Its 1-pole design makes it an ideal fit for single-phase circuits in panelboards, switchboards, and control panels, helping you keep wiring simple without compromising safety or performance.

Designed for reliable operation, this MCB features a C-type trip curve paired with a 50 A rating. That combination provides quick fault clearance for short circuits while tolerating normal inrush currents common to motors, lighting, and other general-purpose loads. In practical terms, you get steady protection against overloads and unexpected faults, reducing the risk of damage to equipment and downstream circuits.

• 1-Pole configuration: streamlined protection for single-phase circuits in distribution panels and control enclosures.
• Trip curve and rating: C-type protection with a 50 A rating, balancing fast fault response with tolerance for inrush loads.
• Versatile deployment: suitable for industrial, commercial, and OEM applications where dependable overcurrent protection and safe operation are critical.
• Reliable ABB quality: built to consistent standards, delivering predictable protection in panelboards, switchboards, and motor control centers.

Ideal use scenarios include protecting feeders in distribution panels for small industrial machines, safeguarding single-phase circuits in commercial installations, and serving as a dependable protection device within OEM equipment where compact, reliable MCBs are essential. The S201-C50 helps you minimize downtime by ensuring quick, clean trips when faults occur, while staying compact enough to fit in tighter control cabinets.

Practical installation and operational tips:

• Match the circuit load to the 50 A rating to ensure optimal protection without nuisance trips.
• Place the S201-C50 where single-phase protection is required, such as dedicated control circuits or motor-driven loads in panel assemblies.
• When evaluating protection needs, consider the typical inrush characteristics of the connected equipment to confirm the C-type curve is appropriate.
