Installation and person protection – ABB DSH201 C20 AC30 residual current circuit breaker with overcurrent protection

This circuit breaker combines short-circuit and leakage current protection, providing comprehensive safety in electrical installations. It is an essential device for both new and modernized facilities where the priority is to protect people and equipment. Characteristic C makes it cope well with shock loads, such as starting motors or compressors.

The DSH201 C20 AC30 circuit breaker is a single-pole device with a connected neutral pole (1P+N), designed to operate in circuits with a voltage of 230V and a frequency of 50Hz. Its rated current is 20A, and the rated short-circuit breaking capacity is 6kA – which guarantees effective disconnection of the circuit in the event of a failure. Additionally, the leakage current sensitivity of 30mA ensures a quick response in the event of an electric shock hazard.

The circuit breaker design has been designed for easy mounting on a TH35 rail. It occupies 2 modules, allowing for optimal use of space in the switchgear. Solid construction with high-quality materials guarantees long-lasting and reliable operation. Terminal blocking prevents accidental loosening of connections, and clear markings facilitate identification and operation of the device.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical devices with moderate power consumption.
• Overload and short-circuit protection: characteristic C provides effective protection against the effects of overloads and short circuits in the electrical installation.
• Leakage current protection: high leakage current sensitivity (30mA) minimizes the risk of electric shock.
• Easy installation: compact dimensions (2 modules) and the possibility of mounting on a TH35 rail facilitate installation.
• Safety of use: terminal blocking prevents accidental loosening of connections, and the IP2X degree of protection protects against touching live parts.
• Compliance with standards: meets the requirements of EN 61009 and IEC 60947-2, which guarantees safety and reliability of operation.
• Rated short-circuit breaking capacity Icn: 6kA according to EN 61009-1 and 10kA according to IEC 60947-2 – high parameters ensuring effective protection of the installation.
• Connection wire cross-section: possibility of connecting stranded wires with a cross-section of 25 mm² and solid wires with a cross-section of 25 mm².
