Circuit breaker, C characteristic, 6 kA, 13 A, 3P SZ203-C13 2CDS253025R0134

Overcurrent circuit breaker from the S203 series is a reliable protection for electrical installations, designed for both professional and home use. The device is characterized by high efficiency in protecting against overloads and short circuits, ensuring safety of use and durability of the installation. Made of high-quality materials, it guarantees long life and stable operation in various conditions.

Product features and application

This three-pole (3P) overcurrent circuit breaker with a rated current of 13A and characteristic C is designed to protect electrical circuits with a rated voltage of 400V. Characteristic C means that the circuit breaker reacts with a delay to short-term current surges, making it an ideal solution for protecting circuits with devices with high inrush current – such as motors or transformers. The rated short-circuit breaking capacity Icn is 6kA at 400V, which ensures effective protection in the event of a short circuit. The width of the device, 3 modules (54mm), allows for easy mounting in standard distribution boards.

Advantages and benefits

• Versatile application: Suitable for protecting various electrical circuits in residential, commercial and industrial buildings.
• High selectivity: Characteristic C provides appropriate selectivity in combination with other circuit breakers in the installation, minimizing the risk of unnecessary tripping of circuits.
• Safety of use: Provides effective protection against overloads and short circuits, protecting electrical appliances and the installation from damage.
• Durable construction: Made of high-quality materials resistant to environmental conditions, which guarantees long life and reliability.
• Easy installation: Compact dimensions (69 mm mounting depth) and a width of 3 modules facilitate installation in standard distribution boards.
• Wide temperature range: The ability to operate in a temperature range from -25°C to 55°C makes the device suitable for use in various climatic conditions.
• Compliance with standards: Meets the requirements of IEC/EN 60898 and IEC/EN 60947-2 standards, which confirms its safety and quality.

Construction and parameters

The circuit breaker has a protection degree of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The cross-section of the connectable single-wire conductor can range from 0.75 mm² to 35 mm², and the multi-wire conductor from 0.75 mm² to 25 mm². The device has energy limitation class 3 and overvoltage category III, which provides additional safety in the event of overvoltages in the electrical installation. The rated impulse withstand voltage (Uimp) is as high as 4kV, which proves high resistance to sudden voltage surges. The possibility of additional equipment allows you to adapt the circuit breaker to specific installation needs.
