The DRCBO3C16/0.03/1N-F from Doepke is a highly advanced combination RCD/MCB switch that integrates both residual current protection and circuit protection in a single device. This innovative product protects individuals from hazardous residual currents and electrical systems from short circuits and overloads. The switches in the DRCBO series are independent of the mains voltage and offer a high rated switching capacity, making them a reliable choice for various applications. Thanks to separate indicators, users can quickly get an overview of the current operating status. The DRCBO switches are also sensitive to mixed frequencies and provide protection against pulse and alternating fault currents that deviate from the standard frequency. Their increased surge current and lightning resistance make them particularly robust and durable. Installation is simple and quick on a mounting rail, facilitating the setup process. - Mixed frequency sensitivity for comprehensive protection against fault currents - High short-circuit resistance for enhanced safety - Separate indicators for a quick overview of the operating status - Tristable toggle switch for easy installation and removal - Quick mounting on a rail for straightforward installation.
