Doepke DFS4 063-4/0.30-PVFI Residual Current Circuit Breaker 4-Pole 63 A 300 mA Type F 09146804

Residual current circuit breaker with 4 poles, 63 A rated current and 300 mA residual current, specifically designed for photovoltaic systems and circuits with frequency converters. The Type F (PVFI) RCCB detects sinusoidal AC, pulsating DC and mixed frequency residual currents up to 1 kHz, ensuring reliable protection in modern electrical installations.

Advantages

Type F tripping characteristic provides comprehensive protection for PV inverters and electronic loads. High surge current withstand capability of 3 kA prevents nuisance tripping. Compact 4-module width saves space on DIN rail. Wide terminal capacity from 1.5 to 50 mm² solid conductors simplifies installation.

Suitable for

• Photovoltaic (PV) systems with transformerless inverters
• Frequency converter circuits
• Industrial control panels with electronic operating equipment
• Three-phase distribution boards requiring residual current protection
