Doepke DOEP DFS4 063-4/0,10-B SK Residual current circuit breaker DFS4 4-p

The Doepke DFS4 063-4/0,10-B SK residual current circuit breaker is a highly advanced device designed to protect people, animals, and electrical systems. This residual current circuit breaker (RCCB) disconnects the power supply when dangerously high fault currents occur, providing an essential safety function in electrical installations. The DFS4 is available in a compact design and is suitable for both single-phase and three-phase networks. With a high rated current of up to 125 A and a type B tripping characteristic, this switch is particularly versatile. The large double-decker terminals allow for the use of large conductor cross-sections, while the tripped position of the multifunction switch makes troubleshooting easier. Additionally, the switch is all-current sensitive and offers high immunity to operational leakage and fault currents, making it a reliable choice for modern electrical systems.

• Two- or four-pole version for flexible applications
• High immunity to operational fault currents starting from 1 kHz
• All-current sensitive for frequencies from 0 Hz to 150 kHz
• Increased surge current and lightning resistance
• Optimized for systems without fire protection requirements.
