ABB S201-B16 (2CDS251001R1165) Compact S200 Miniature Circuit Breaker  

1. Key Parameters

• Product Model: S201-B16 (Order Code: 2CDS251001R1165)
• Product Series: ABB S200-Series Compact Miniature Circuit Breakers (Low-Voltage Protection)
• Core Function: Overload protection; short-circuit protection; low-voltage circuit isolation; current limiting.

2. Core Features

• Compact Design: 18mm narrow width saves DIN rail space, ideal for densely wired control cabinets or distribution boxes.
• Reliable Protection: B-curve design suits resistive/capacitive loads (e.g., lighting, small motors), avoiding false tripping while ensuring fast short-circuit response.
• Easy Installation: Tool-free DIN rail mounting and clear terminal markings simplify on-site wiring and replacement.
• S200 Series Compatibility: Integrates with other ABB S200 series accessories (e.g., auxiliary contacts, shunt trips) for expanded protection functions.

3. Application Fields

• Industrial Control Cabinets: Protects power loops of ABB PLCs, drives, and sensors in industrial automation control systems.
• Commercial/Residential 配电: Guards lighting circuits, socket outlets, and small household appliances in commercial buildings or residences.
• Equipment Power Supplies: Provides overload/short-circuit protection for power inputs of small industrial equipment (e.g., pumps, fans, instrumentation).

4. Precautions

• Current Matching: Ensure load current ≤16A; overloading causes frequent tripping or breaker damage.
• Pole & Curve Selection: Confirm 1-pole configuration and B-curve match the load type (avoid using for inductive loads requiring C/D curves).
• Installation: Follow electrical safety codes (disconnect power before wiring); ensure tight terminal connections to prevent overheating.
• Spare Parts: Use genuine ABB S201-B16 units—non-genuine breakers may have insufficient breaking capacity, leading to circuit hazards.
