Doepke 09147848HD DFS 4-pole 63A 0.50A type B SK N-li HD RCD circuit breaker all-current sensitive

The Doepke 09147848HD DFS 4-pole 63A 0.50A Type B SK N-li HD RCD is a highly advanced residual current device designed for use in single-phase and three-phase networks. This protective switch provides reliable protection for people, animals, and electrical systems by immediately disconnecting the power supply in the event of dangerously high fault currents. With its compact design, occupying only four modular units, it is ideal for mounting on DIN rails. Type B is all-current sensitive and can detect fault currents over a wide frequency range from 0 Hz to 150 kHz, making it particularly suitable for applications where DC fault currents may occur. The robust construction and special materials ensure that the switch operates reliably even under extreme conditions, such as corrosion and temperature fluctuations. Additionally, the tripped position of the multifunction switch knob facilitates troubleshooting, while the free labeling software supports the labeling of the switches.

• All-current sensitive Type B for frequencies from 0 Hz to 150 kHz
• Increased surge current and lightning resistance
• Lower response sensitivity at higher frequencies
• Airtight encapsulated trigger in a special alloy for corrosion protection
• Stainless steel switch lock for additional robustness.
