Overcurrent circuit breaker, 3P, C characteristic, 13A, 6kA, AC | S203-C13 2CDS253001R0134

Electrical installation protection with S200 series circuit breaker

This three-pole circuit breaker with C characteristic is a reliable solution for protecting electrical installations against overloads and short circuits. Designed for safety and durability, it is suitable for both domestic and industrial installations. Manufactured by ABB, a renowned manufacturer in the electrical industry, it guarantees high quality and compliance with applicable standards.

Functionality and technical parameters

The S203-C13 circuit breaker with a rated current of 13A and a short-circuit breaking capacity of 6kA (at 400V) effectively protects circuits against the effects of sudden current increases. The C characteristic means that the circuit breaker reacts more slowly to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high starting current – this avoids unnecessary tripping of the circuit during normal operation. The short-circuit breaking capacity of 10kA at 400V and 20kA at 230V ensures effective protection even in the event of serious failures.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical appliances.
• DIN rail mounting: standard width of 3 modules facilitates integration with existing switchboards.
• Wide range of wire cross-sections: possibility of connecting solid wires with a cross-section from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm², provides flexibility during installation.
• Durability and reliability: resistant to environmental conditions, designed to operate at temperatures from -25°C to +55°C.
• Safety: meets the requirements of IEC 60947-2 and EN 60898 standards, ensuring a high level of protection.

Construction and mounting

The circuit breaker is characterized by a solid construction and compact dimensions (installation depth 69 mm). The IP20 degree of protection provides protection against finger contact, which increases safety. Mounting is done by snapping onto a standard DIN rail, which significantly speeds up the installation process and allows for easy replacement if necessary. Additional possibility of expansion with accessories allows to adapt the functionality of the circuit breaker to individual user needs.
