Overcurrent circuit breaker, 3P, Z characteristic, 1.6A, 6kA, AC | S203-Z1.6 2CDS253001R0258

Reliable protection of electrical installations – ABB S203 series circuit breaker

This three-pole overcurrent circuit breaker from ABB’s S203 series is a key element in protecting any electrical installation. Designed to protect against overloads and short circuits, it ensures safe use and reliable operation. It is characterized by a high short-circuit breaking capacity, making it an ideal choice for both domestic and industrial installations.

Made of high-quality materials, this circuit breaker guarantees long-lasting and trouble-free operation. Its compact dimensions (3 module width) make it easy to install in electrical panels with limited space. Characteristic Z provides a quick response to an increase in short-circuit current, minimizing the risk of damage to the installation and equipment.

Parameters and application

The S203-Z1.6 circuit breaker with a rated current of 1.6A is particularly recommended for protecting lighting circuits, socket outlets and other devices with low power consumption. Its short-circuit breaking capacity of 6kA at 400V and 10kA at 230V guarantees effective protection even in the event of serious disturbances in the electrical network. Suitable for operation at temperatures from -25°C to +55°C, it will perform well in a variety of environmental conditions.

Mounting on a DIN rail is simple and intuitive, which translates into time savings during installation. The possibility of additional equipment allows the circuit breaker to be adapted to the specific needs of a given facility. Compliance with EN 60898 and IEC 60947-2 standards confirms its high level of safety and reliability.
