The ABB DS301CA-B16/0,03 FI/LS-Schalter is a compact single-pole+neutral residual current circuit breaker with overload protection, designed for safe 1P+N circuits in homes and light commercial settings. It delivers 30 mA residual current protection, Type A fault detection, and a 6 kA short-circuit rating with a 16 A nominal current (B16).

Key Features & Design

• Residual current protection: Type A with 30 mA sensitivity for AC faults and pulsating DC currents
• Nominal current: B16 (16 A) with a B-curve overcurrent characteristic
• Configuration: 1P+N device combining leakage protection with overcurrent protection (FI/LS)
• Short-circuit rating: 6 kA breaking capacity
• Model reference: ABB DS301CA-B16/0,03, part number 2CSR255163R1165

Performance / Benefits

This device protects people and equipment by quickly disconnecting the circuit when leakage or overload occurs, reducing the risk of electric shock and electrical damage. Type A protection covers both alternating currents and pulsating DC faults, making it suitable for modern electrical loads. With a 6 kA breaking capacity and 16 A nominal current, it provides reliable protection for typical domestic and light commercial circuits, helping you meet safety standards with confidence.
