Overcurrent circuit breaker, 3P, C characteristic, 4A, 6kA, AC | S203-C4 2CDS253001R0044

Reliable protection of electrical installations – S200 series circuit breaker

This three-pole circuit breaker with C characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. Designed to operate in AC systems, it offers a high short-circuit breaking capacity – up to 6kA at 400V, making it an ideal choice for both home and commercial installations.

Functionality and parameters tailored to your needs

The S203-C4 circuit breaker with a rated current of 4A has been designed for a wide range of applications. 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 inrush currents – e.g. pumps, air conditioners or power tools. This will avoid unnecessary tripping of the circuit during normal operation of these devices.

The rated short-circuit breaking capacity (Icn) of 6kA at 400V and 20kA at 230V guarantees a quick and safe response in the event of a failure. Made of high-quality materials, resistant to environmental conditions in the temperature range from -25°C to 55°C, and meeting the standards of overvoltage category III and pollution degree III – ensures long-lasting and reliable operation. A width of 3 modules makes it easy to install in standard distribution boards.

• Versatility: The ability to connect solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm², provides flexibility in choosing cables for specific needs.
• Safety: Energy limitation class 3 and high impulse voltage resistance (4kV) provide additional protection for the installation and users.
• Compatibility: The possibility of mounting additional equipment allows for expanding the functionality of the circuit breaker in the future.
• Durability: Made of high-quality materials guarantees long-lasting and trouble-free operation of the device in various environmental conditions.
