Overcurrent circuit breaker, 3P, characteristic C, 80A, 6kA, AC | S203-C80 2CDS253001R0804

Reliable protection of electrical installations with S203-C80 circuit breaker

This three-pole circuit breaker with C characteristic is a key element of every safe and reliable electrical installation. Designed to protect against overloads and short circuits, it provides peace of mind for both installers and end-users. Model S203-C80, with a rated current of 80A and a short-circuit breaking capacity of 6kA, is perfect for protecting electrical circuits in residential and commercial buildings.

Solid construction and high performance

This circuit breaker is characterized by a compact design, taking up 3 modules on a DIN rail. Its housing with an IP20 degree of protection provides protection against touch and dust. The rated insulation voltage Ui of 440V and impulse withstand voltage of 4kV guarantee safe operation even in difficult conditions. Power losses of 39.2W minimize the impact on the energy efficiency of the installation.

Versatility and easy installation

The S203-C80 circuit breaker is compatible with solid conductors from 2.5 to 50 mm² and stranded conductors from 4 to 35 mm². The C characteristic provides a delayed tripping response to short-term overloads, which is particularly important for devices with motors or other elements generating high starting current – this helps to avoid unnecessary tripping of the circuit during normal operation. The possibility of additional equipment increases the functionality of the device, adapting it to the specific needs of the installation. A wide range of operating temperatures from -25°C to 55°C allows it to be used in various environmental conditions. The short-circuit breaking capacity of 6kA at 400V and 10kA at 230V ensures effective protection against the effects of serious failures.
