The DOEP DFS4 125-4/0.03-A V500 290/500V is a highly advanced residual current circuit breaker (RCCB) designed for use in single-phase and three-phase networks. This compact switch provides reliable protection for people, animals, and electrical installations by immediately disconnecting the power supply in the event of dangerously high fault currents. With a width of only four modular units, it is particularly space-saving and suitable for mounting on DIN rails. The switch is capable of monitoring fault currents of up to 125 A and offers high short-circuit resistance. The integrated double-decker terminals allow for the connection of large conductor cross-sections, simplifying installation. Additionally, the switch features a switching position indicator and a viewing window for labeling stickers, making handling and troubleshooting easier. The network and auxiliary voltage-independent tripping, as well as sensitivity to pulsating DC fault currents, make it a versatile solution for various applications.

• Two or four-pole design for flexible applications
• High short-circuit resistance for increased safety
• Double-decker terminals for large conductor cross-sections
• Multifunctional switching knob with three positions for easy operation
• Viewing window for custom labeling and easy identification.
