Doepke DFS4 063-4/0.03-B SK

The Doepke DFS4 063-4/0.03-B SK is a highly advanced residual current circuit breaker (RCCB) designed for use in single-phase and three-phase networks. This switch provides reliable protection for people, animals, and electrical systems by immediately interrupting the power supply in the event of dangerously high fault currents. With a compact design that occupies only four modular units, the DFS4 is suitable for both standard applications and more demanding environments. The devices are available in various versions and support rated currents of up to 125 A. The large double-deck terminals allow for the use of conductors with larger cross-sections, while the special tripping characteristics and all-current sensitivity of type B ensure high safety. Additionally, the switch is shock current and lightning resistant, making it particularly robust. The integrated labeling software simplifies labeling and documentation, which facilitates installation and maintenance.

• Two- or four-pole design for flexible applications
• All-current sensitive at frequencies from 0 Hz to 150 kHz
• Increased shock current and lightning resistance
• Reduced tripping sensitivity at higher frequencies
• Airtight encapsulated tripping mechanism in a special alloy for corrosion protection.
