Overcurrent circuit breaker, 3P, Z characteristic, 4A, 6kA, AC | S203-Z4 2CDS253001R0338

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 for demanding applications.

Characteristics and application

The S203-Z4 circuit breaker with a rated current of 4A and Z characteristic is designed to protect circuits with high inrush currents. The Z characteristic means a delayed response to short-term current surges, allowing for smooth starting of devices such as motors or transformers. It provides effective protection against the effects of overloads and short circuits – just like any circuit breaker in this class. A width of 3 modules makes it easy to install in standard distribution boards.

Construction and user parameters

The circuit breaker is made of high-quality materials, which guarantees its durability and resistance to environmental conditions. Adapted to work at temperatures from -25°C to 55°C, it can be used in a wide range of applications. The possibility of mounting additional equipment allows you to adapt the functionality of the circuit breaker to individual needs. The cross-section of solid conductors from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm² ensures compatibility with various types of conductors. Energy limitation class 3 and surge category III indicate a high level of protection against interference in the electrical network. Protection degree IP20 provides protection against accidental contact. Power losses are 7.2W at rated voltage 400V.
