Overcurrent circuit breaker, 3P, C characteristic, 2A, 6kA, AC | S203-C2 2CDS253001R0024

Reliable protection of electrical installations with S200 series circuit breaker

This three-pole circuit breaker with C characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. It is a device that will work both in newly built installations and during the modernization of existing ones.

The S203-C2 circuit breaker with a rated current of 2A and a short-circuit breaking capacity of 6kA is designed to operate in AC networks with a voltage of 400V. Its compact dimensions (width of 3 modules, depth of 69mm) allow for easy mounting in distribution boards. The C characteristic provides delayed tripping during short-term overloads, which is particularly important for devices with motors or other elements generating high starting current – it will not cause unnecessary disconnection of the circuit during device startup.

Solid construction and compliance with standards

The circuit breaker meets the requirements of overvoltage category III and pollution degree 3, which guarantees its reliability even in difficult environmental conditions. Its housing is made of high-quality materials, providing resistance to mechanical damage and external factors. The device has a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. The rated impulse withstand voltage Uimp is as high as 4kV.

Mounting and application

The circuit breaker is designed for mounting on a DIN rail and does not require additional tools. It accepts solid conductors with a cross-section from 0.75 to 35 mm² and stranded conductors from 0.75 to 25 mm². The possibility of using additional equipment allows you to adapt the functionality of the circuit breaker to the specific needs of the installation. The rated short-circuit breaking capacity Icn at 400V is 6kA, and Icu at 230V as much as 20kA – this ensures effective protection in the event of a short circuit. The device operates in the range of ambient temperatures from -25°C to +55°C.
