Overcurrent circuit breaker, 3P, Z characteristic, 0.5A, 6kA, AC | S203-Z0.5 2CDS253001R0158

Electrical installation protection with S200 series circuit breaker

This three-pole circuit breaker with Z characteristic is a reliable protection for your electrical installation. Designed to protect against overloads and short circuits, it ensures safe use and long-term reliability. It is characterized by a high short-circuit breaking capacity – up to 6kA at 400V, making it a suitable choice even in demanding conditions.

This circuit breaker, with a width of 3 modules, can be used in both domestic and commercial installations. Its compact dimensions (installation depth 69 mm) facilitate mounting in distribution boards. Adapted to operate at temperatures from -25°C to 55°C, it will perform well in various environments.

Characteristics and application

The Z characteristic means that this circuit breaker reacts very quickly to current increase, which is particularly important in circuits with devices generating high inrush currents – for example, with electric motors or transformers. This ensures effective protection against damage resulting from sudden load surges. The rated current of 0.5A makes it ideal for protecting circuits with low power consumption, where precision is key.

The circuit breaker meets the requirements of overvoltage category III and pollution degree 3, which guarantees its resistance to interference and reliability in difficult industrial and commercial conditions. 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 flexibility during installation. Power losses of only 7.2W minimize the impact on the energy efficiency of the system.
