The ABB DS301CB6A30 is a compact FI/LS-Schalter that combines residual-current protection with overcurrent protection for safe, reliable electrical circuits. Designed for both residential and commercial installations, it helps protect people and equipment from leakage currents and overloads.

Key Features & Design

• Protection type: FI/LS-Schalter (RCD + MCB) with Type A residual-current detection and Characteristic B trip curve
• Residual current sensitivity: 30 mA
• Rated current: 6 A
• Product code: 2CSR255163R1065
• Application: Designed for standard electrical installations requiring combined leakage and overcurrent protection

Performance / Benefits

By quickly disconnecting the circuit on leakage or overload, the DS301CB6A30 reduces the risk of electric shock and fire while keeping circuits protected from nuisance trips. This two-in-one device simplifies panel design, lowers component count, and supports safe, compliant electrical installations.
