## Summary description

The ABB S201-B50 miniature circuit breaker is designed for reliable electrical protection in residential and commercial installations. It features a 50 A rated current, Type B trip curve, and a 6000 A breaking capacity with a total power loss of 3.25 W. Operating at a frequency of 50 - 60 Hz, this single-pole device effectively safeguards circuits against overloads and short circuits, ensuring system safety and continuous operation.

## Long description

The ABB S201-B50 miniature circuit breaker is engineered for reliable electrical protection in residential, commercial, and industrial installations. Designed as a single-pole device, it effectively safeguards electrical circuits against both overloads and short circuits to ensure system safety and continuous operation. This miniature circuit breaker utilizes two distinct tripping mechanisms, combining a delayed thermal tripping mechanism for overload protection with an electromechanic tripping mechanism for short circuit protection. Built to comply with international standards IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, this device provides dependable performance and current-limiting capabilities.
Advantages
The ABB S201-B50 miniature circuit breaker offers robust current-limiting technology that helps minimize let-through energy during fault conditions, protecting downstream wiring and equipment. Its dual tripping mechanisms ensure precise response times for different types of electrical faults. The compact single-pole design features a standard width of 17.5 mm, allowing efficient use of space within distribution boards and consumer units. Additionally, the unit supports bottom-fitting auxiliary contacts, which can be mounted to save up to fifty percent of installation space compared to traditional side-mounted configurations.
Suitable for
Residential electrical distribution boards
Commercial building sub-circuits
Industrial control panels
Overload and short-circuit protection in single-pole applications
This device may not be suitable for multi-phase circuits requiring two, three, or four poles, as it is strictly a single-pole miniature circuit breaker. It is also not designed for applications where the required rated current exceeds 50 A or where specialized trip curves other than Type B are mandated by specific installation standards.

Installation of the ABB S201-B50 miniature circuit breaker should be performed by a qualified electrician in accordance with local and national electrical codes. The device is designed for mounting on standard DIN rails within suitable enclosures providing at least IP20 protection. Ensure that all terminal connections are securely tightened to the manufacturer's recommended torque specifications to prevent loose connections and potential overheating.
What to consider before purchase
Verify that the 50 A rated current matches the electrical load requirements of your circuit
Ensure that a single-pole (1P) configuration is appropriate for your wiring layout
Check that the Type B trip curve aligns with the expected inrush currents of your connected loads
Confirm compatibility with your existing distribution board and DIN rail mounting space
Always disconnect the main power supply before installing, inspecting, or servicing the circuit breaker to prevent electrical shock or equipment damage.
