Overcurrent circuit breaker, 3P, B characteristic, 6A, 6kA, AC | S203-B6 2CDS253001R0065

Reliable protection of electrical installations – ABB S203-B6 circuit breaker

This three-pole circuit breaker with B 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 fires. It is an ideal solution for both home, commercial and industrial applications.

The S203-B6 circuit breaker is characterized by a high short-circuit breaking capacity – up to 6kA at 400V AC, which guarantees a quick response in emergency situations. The B characteristic means a delayed tripping time for short-term overloads, which is particularly important for devices with motors or other elements generating high inrush currents. This avoids unnecessary tripping of the circuit during normal operation.

Solid construction and easy installation

The circuit breaker is mounted on a DIN rail, ensuring quick and convenient installation. Compact dimensions (width of 3 modules) allow for efficient use of space in the switchgear cabinet. Made of high-quality materials, it guarantees long-lasting and reliable operation even in harsh environmental conditions (operating temperature from -25°C to 55°C). The IP20 degree of protection provides protection against touch and ingress of solid objects.

Parameters tailored to your needs

This circuit breaker has a rated current of 6A, making it ideal for protecting circuits with moderate power consumption. It is compatible with most standard electrical installations thanks to the rated voltage of 400V AC. It provides high resistance to short-circuit currents thanks to the rated short-circuit breaking capacity Icn of 6kA (at 400V), and Icu: 10kA (at 400V) and 20kA (at 230V). The possibility of connecting solid conductors with a diameter of 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm² provides installation flexibility. Surge category III and pollution degree 3 guarantee reliable operation in demanding conditions, and power losses of only 6W affect the energy efficiency of the installation.

This circuit breaker is not only a protective element, but also an investment in safety and peace of mind. Compliance with EN 60898-1 and EN60947-2 standards confirms its high quality and reliability.
