Overcurrent circuit breaker, 3P, D characteristic, 32A, 6kA, AC | S203-D32 2CDS253001R0321

ABB S200 series overcurrent circuit breaker is a reliable protection for electrical installations, designed for both home and industrial use. This three-pole circuit breaker, with a rated current of 32A and D characteristic, effectively protects circuits against overloads and short circuits. Its compact dimensions (3 module width) facilitate installation in distribution boards.

Application and functionality

The S203-D32 circuit breaker is used to protect electrical circuits powering various types of receivers, including devices with high starting current – such as motors or transformers. The D characteristic provides delayed tripping, which avoids unnecessary shutdowns during short-term current surges when starting these devices. The rated short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) guarantees effective protection in the event of serious disturbances in the network. It meets the requirements of IEC EN 60898-1 and IEC EN 60947-2 standards, confirming its safety and reliability.

Construction and installation

The circuit breaker is designed for mounting on a DIN rail, ensuring quick and easy installation. Its housing made of high-quality materials provides durability and resistance to mechanical damage. The possibility of connecting wires with a cross-section from 0.75 mm² to 25 mm² (stranded) or from 0.75 mm² to 35 mm² (solid) provides flexibility when selecting power cables. The degree of protection IP20 means that the device is protected against finger contact, but is not resistant to water ingress. Operation in an ambient temperature from -25°C to +55°C allows it to be used in various environmental conditions.

Key features and benefits

• D characteristic: Delayed tripping ideal for circuits with devices with high starting current – motors, transformers, pumps. Avoids unnecessary shutdowns during device start-up.
• High short-circuit breaking capacity: Provides effective protection of the installation in the event of a short circuit – both at 230V (20kA) and 400V (10kA).
• Compact dimensions: Only 3 modules wide saves space in the distribution board.
• Versatility: Suitable for home and industrial applications.
• Compliance with standards: Meets the requirements of IEC EN 60898-1 and IEC EN 60947-2 standards – a guarantee of safety and reliability.
• Wide range of wire cross-sections: Allows connection of wires of different thicknesses (up to 35mm²), providing installation flexibility.
• Durable construction: Made of high-quality materials ensuring long device life.
