Product details
The Doepke RCD switch DFS4 040-4/0.03-A NA is a highly advanced residual current device designed for use in single-phase and three-phase networks. It provides reliable protection for people, animals, and electrical systems by automatically disconnecting the power supply in the event of dangerously high fault currents. With a compact design that occupies only four modular units, this switch is ideal for applications where space is limited. The DFS4 is available in Type A configuration, meaning it responds to both alternating and pulsating direct fault currents. The integrated LED display indicates emergency disconnection, while the ability to connect multiple switches in parallel enhances installation flexibility. The easy mounting on a DIN rail and the large double-decker terminals, which can accommodate large conductor cross-sections, make this switch a practical choice for various electrical installations.
- Network and auxiliary voltage-independent tripping for increased safety
- Built-in emergency stop button for quick shutdown in emergencies
- LED display for indicating emergency disconnection or wire break
- Compact size for space-saving installation
- Complete disconnection properties without requiring additional power supply.
