Doepke 091448HD DFS 4-pole 63A 0.03A Type B SK N-li HD RCD circuit breaker all-current sensitive

The Doepke DFS 4-pole 63A 0.03A Type B SK N-li HD residual current circuit breaker is a highly advanced device designed for use in single-phase and three-phase networks. This circuit breaker 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, it is ideal for mounting on DIN rails. Type B is sensitive to all currents and can detect both smooth DC fault currents and high-frequency fault currents up to 150 kHz. The devices are particularly robust and short-circuit resistant, making them suitable for use in demanding environments. Additionally, they are equipped with a special alloy and a stainless steel switch lock to resist corrosion and environmental influences. The integrated labeling software simplifies the labeling and documentation of circuits, making handling and maintenance easier.

• All-current sensitive Type B for comprehensive protection against fault currents
• Suitable for single-phase and three-phase networks with a rated voltage of up to 400 V
• Robust construction with enhanced protection against corrosion and harmful gases
• Easy fault diagnosis through the tripped position of the multifunction switch button
• Compatible with large conductor cross-sections thanks to the large double-deck terminals.
