ABB DS301CA-C16/0,03 FI/LS-Schalter is a compact residual current circuit breaker with overcurrent protection designed for single‑phase circuits. It combines Type A leakage detection with 30 mA sensitivity, a 16 A rating (C16), and robust 6 kA breaking capacity, making it suitable for homes and light commercial installations.

Key Features & Design

• Type: FI/LS-Schalter (RCD) Type A for detecting AC and pulsating DC residual currents
• Sensitivity: 30 mA residual current protection for enhanced personal safety
• Rated current: C16 (16 A) with a C‑curve tripping characteristic for typical loads
• Breaking capacity: 6 kA (short-circuit withstand)
• Pole configuration: 1P+N (single pole plus neutral) for compact, easy installation
• Product code: 2CSR255163R1164

Performance / Benefits

By continuously monitoring the balance between live and neutral currents, this ABB device disconnects the circuit at the first sign of leakage, reducing the risk of electric shock and helping prevent electrical fires. The 16 A rating is well-suited for common household circuits, while the 6 kA breaking capacity provides reliable protection against short circuits. Type A detection covers a wide range of leakage scenarios, including many electronic devices and power supplies often found in modern installations. The 1P+N configuration keeps wiring simple and tidy in consumer units, delivering dependable protection with straightforward integration in new builds, renovations, or upgrades.
