Overcurrent circuit breaker, 3P, Z characteristic, 6A, 6kA, AC | S203-Z6 2CDS253001R0378

Electrical installation protection with S200 series circuit breaker

This three-pole circuit breaker with Z characteristic is a key element of every safe electrical installation. It provides reliable protection against overloads and short circuits, protecting both devices and people. Designed to operate in AC networks with a voltage of 400V and a frequency of 50-60Hz, it is an ideal solution for a wide range of applications – from home installations to commercial facilities.

This circuit breaker, with a width of 3 modules, is characterized by a high short-circuit breaking capacity – up to 6kA at 400V (according to EN 60898) and 10kA at 400V (according to IEC 60947-2). Thanks to this, it effectively reacts to sudden current surges, minimizing the risk of damage and fires. The Z characteristic means a delayed response to current increase, which is particularly important in the case of loads with high inrush current, such as motors or transformers.

Solid construction and universal mounting

The circuit breaker is made of high-quality materials, which guarantees its durability and reliability. Its housing with an IP20 degree of protection provides protection against contact and ingress of solid objects. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) or from 0.75 mm² to 25 mm² (stranded) provides great flexibility during installation. The device operates in a wide range of ambient temperatures (-25°C to +55°C), which allows it to be used in various environmental conditions. Additionally, the possibility of expanding with accessories increases the functionality of the circuit breaker and allows it to be adapted to individual needs.

• High short-circuit breaking capacity: 6kA at 400V ensures effective protection of the installation against serious failures.
• Z characteristic: ideal for loads with high inrush current – motors, transformers, etc.
• Wide range of wire cross-sections: allows easy connection of different types of wires.
• Durable construction: guarantees long-lasting and reliable operation of the device.
• Expandability: thanks to compatibility with additional accessories, the functionality of the circuit breaker can be adapted to specific installation requirements.
• Energy limitation class 3: provides adequate protection in the event of an electric arc.
• Surge category III: resistance to overvoltages occurring in power grids.
