Doepke FISwitch DFS 4 04040,30A R

The Doepke FIS switch DFS 4 04040, 30A R is a highly advanced residual current circuit breaker (RCCB) 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 suitable for both residential and commercial applications. The devices are available in various versions and support rated currents up to 125 A. The integrated double-decker terminals allow for the connection of large conductor cross-sections, while the type A tripping characteristic ensures high sensitivity to alternating and pulsating direct fault currents. The user-friendly multifunction switch knob display simplifies operation and troubleshooting, while the free labeling software makes it easy to label the switches.

• Sensitive to alternating and pulsating direct fault currents (Type A)
• High short-circuit resistance
• Double-decker terminals on both sides for large conductor cross-section
• Multifunction switch knob with three positions: on, off, tripped.
