The DOEP FI/LS combination from Doepke is an innovative protective switch that combines the functions of a residual current circuit breaker (FI) and a miniature circuit breaker (LS) in a compact device. This combination offers comprehensive protection for people and electrical systems by safeguarding against both fault currents and short-circuit and overload situations. With a rated breaking capacity of 6 kA and an all-current sensitive tripping characteristic, this switch is suitable for a wide range of applications. The DRCBO 4 models are particularly robust and short-circuit resistant, making them ideal for use in demanding environments. The integrated trip indicator and labeling window allow for easy handling and documentation. The SK characteristic curve ensures high system availability by minimizing fault-related tripping, while the B tripping characteristic provides standard protection for lighting and socket circuits. Thus, this combination is a reliable solution for modern electrical installation needs.

• All-current sensitive for frequencies from 0 Hz to 150 kHz
• Low sensitivity to higher frequencies to avoid installation-related false tripping
• Separate indication of the tripping reason for easy fault diagnosis
• Terminal blocks with a wide cross-section range for flexible connection options
• Quick mounting on DIN rail for easy and time-saving installation.
