Doepke DFS6 063-4/0,03-A NU Residual Current Circuit Breaker 4-Pole 63A 30mA Type A 09144801

The Doepke DFS6 063-4/0,03-A NU stands out as a robust 4-pole residual current circuit breaker (RCCB) engineered for demanding electrical installations. Unlike basic models, it combines a high 63 A rated current with a sensitive 30 mA residual current threshold, delivering reliable protection against both AC and pulsating DC earth faults. Its Type A classification and 10 kA short-circuit withstand capability make it a dependable choice for commercial and industrial distribution boards.

Highlights

• Type A residual current protection – detects AC and pulsating DC leakage currents
• 63 A rated current with 4-pole switching for three-phase and neutral isolation
• 30 mA trip sensitivity for personal and fire protection
• Rated switching capacity of 1000 A and surge current withstand of 3 kA
• Compact 4-module DIN rail mounting (EN 60715)
• Wide terminal range: 1.5–50 mm² solid, 1.5–35 mm² flexible
• Operating temperature from -25 °C to +40 °C

In daily use

Installed on a standard 35 mm DIN rail, the DFS6 063-4/0,03-A NU provides immediate disconnection when residual currents reach 30 mA, preventing electric shock and reducing fire risk. Its instantaneous tripping characteristic ensures fast response, while the IP20 terminal protection (IP40 when installed in a distribution board) guards against accidental contact. With a rated voltage of 230/400 V AC and 50 Hz frequency, it integrates seamlessly into European low-voltage networks. The device meets VDE 0664-10 and EN 61008-1 standards, ensuring compliance and long-term reliability.
