The DOEP DFS4AFI25-4/0.5 is a highly advanced residual current circuit breaker (RCCB) designed for use in single-phase and three-phase networks. With a rated current of 25 A and a rated residual current of 0.5 A, this switch provides reliable protection for people, animals, and electrical installations. The compact design of the device occupies only four modular units, making it ideal for applications with limited space. The switch is independent of network and auxiliary voltage and responds to both alternating and pulsating direct fault currents, which makes it particularly versatile. The large double-deck terminals allow for the connection of conductors with larger cross-sections, while the switching position indicator and the viewing window for labeling stickers facilitate handling and troubleshooting. The multifunctional switch knob with three positions ensures easy operation and clear status indications.

• Two- or four-pole design for flexible applications
• High short-circuit resistance for added safety
• Quick mounting for easy installation on DIN rails
• Multifunctional switch knob with clear positions for simple operation
• Viewing window for individual labeling and better visibility.
