DOEPKE DRCBO 4 B32/0.03/3N RCBO, 32 A, 30 mA, Type A, 4-Pole (3P+N), 6 kA, DIN Rail 9945107

With a rated breaking capacity of 6 kA and a 30 mA residual current sensitivity, the DOEPKE DRCBO 4 B32/0.03/3N delivers robust protection against both overloads and earth leakage currents in a single, space-saving module. This 4-pole (3P+N) RCBO combines the functions of a miniature circuit breaker and a residual current device, ensuring compliance with EN 61009-1 and VDE 0664-20.

Overview

The DRCBO 4 B32/0.03/3N is a residual current circuit breaker with overcurrent protection (RCBO) designed for DIN rail mounting. It features a rated current of 32 A, a rated residual current of 30 mA, and a tripping characteristic of type B, making it suitable for circuits with high inrush currents. The Type A residual current detection covers both alternating and pulsating direct residual currents, providing reliable protection in modern electrical installations.

What stands out

• Combined protection: MCB and RCD in one device, saving space and simplifying installation.
• High breaking capacity: 6 kA short-circuit rating for demanding applications.
• Type A residual current detection: suitable for AC and pulsating DC residual currents.
• Wide terminal capacity: accepts conductors up to 25 mm² solid or 16 mm² flexible.
• Energy limitation class 3: enhances safety by limiting let-through energy during faults.
