Overcurrent circuit breaker, 3P, D characteristic, 20A, 6kA, AC | S203-D20 2CDS253001R0201

ABB S200 series overcurrent circuit breaker is a reliable protection for electrical installations, designed for both domestic and industrial applications. The three-pole S203-D20 model with a rated current of 20A and D characteristic provides effective protection against overloads and short circuits. The rated short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) guarantees safety in the event of a failure.

This circuit breaker is distinguished by its delayed D characteristic, which means it allows for short-term exceeding of the rated current without tripping. This is particularly important when operating devices with electric motors or other loads with high starting current – such as pumps, compressors or power tools. This avoids unnecessary shutdowns and ensures continuity of operation.

The circuit breaker design allows for mounting on a DIN rail, which simplifies and speeds up installation. Compact dimensions (width of 3 modules) allow for efficient use of space in the distribution board. The IP20 degree of protection provides basic protection against contact and ingress of solid objects. The circuit breaker complies with EN 60898-1 and EN 60947-2 standards, confirming its safety and reliability. The cross-section of conductors connected to the circuit breaker can range from 0.75 mm² to 25 mm² for multi-wire cables and from 0.75 mm² to 35 mm² for single-wire cables.

• D characteristic: ideal for circuits with loads with high starting current – motors, compressors, power tools. Allows for short-term exceeding of the rated current without unnecessary tripping.
• Short-circuit breaking capacity: 6kA at 230V and 10kA at 400V – high resistance to the effects of short circuits, ensuring the safety of the installation and equipment.
• DIN rail mounting: quick and easy mounting in the electrical distribution board.
• Compact dimensions: only 3 modules wide – saving space in the distribution board.
• Compliance with standards: EN 60898-1 and EN 60947-2 – guaranteed safety and reliability confirmed by certificates.
• Wide range of conductor cross-sections: possibility of connecting conductors with a cross-section from 0.75 mm² to 35 mm², providing installation flexibility.
• Operating temperature: from -25°C to +55°C - possibility of use in difficult environmental conditions

The S203-D20 circuit breaker is a solid and durable solution that will work in any circuit requiring reliable protection against overloads and short circuits. Its versatility makes it an ideal choice for both professional installers and end-users looking for safe and effective protection of their electrical installation.
