Meet the ABB F204 A-63/0,03 residual-current device—a precise A-type, four-pole protection device designed to safeguard electrical installations from leakage currents. With a 63 A rated current and 30 mA sensitivity, this unit delivers reliable protection for panels and multi‑load systems.

Key Features & Design

• Type: A-type residual-current device
• Poles: 4P configuration for three-phase systems with neutral
• Rated current: 63 A
• Residual current sensitivity: 30 mA
• Model / Part: 2CSF204101R1630
• Application: Protects against leakage currents and short circuits in electrical distribution

Performance / Benefits

This RCD helps prevent electric shock and reduces the risk of electrical fires by rapidly disconnecting circuits when leakage currents are detected. The four-pole design provides robust protection across three-phase systems, while the A-type sensitivity covers both alternating and pulsating direct currents, making it suitable for a wide range of modern loads and equipment. Built to ABB’s standards of reliability, it supports safe, compliant, and continuous operation in electrical distribution boards.
