Overcurrent circuit breaker, 3P, C characteristic, 0.5A, 10kA, AC | S203M-C0.5 2CDS273001R0984

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 and reliable electrical installation. Designed to protect against overloads and short circuits, it provides peace of mind for both installers and end-users. The rated current of 0.5A makes it an ideal choice for securing circuits with lower power consumption, and the high short-circuit breaking capacity (up to 10kA at 400V) guarantees an effective response in emergency situations.

Design and parameters for professionals

The S203M-C0.5 circuit breaker occupies 3 modules on a DIN rail, making it easy to install in distribution boards. Its embedding depth of 69 mm allows for installation even in limited spaces. 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 – avoiding unnecessary tripping of the circuit when starting devices. The rated insulation voltage Ui of 440V and energy limitation class 3 confirm the high quality and safety of the device.

The circuit breaker meets the requirements of overvoltage category III and pollution degree 3, which means it can be used in demanding environmental conditions. Suitable for operation in ambient temperature from -25°C to 55°C, it will perform well in various applications. 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 great flexibility during installation.

Safety and functionality for the end-user

This circuit breaker not only protects the installation from damage but also ensures the safety of household members or employees. In the event of an overload or short circuit, it automatically disconnects the circuit, minimizing the risk of fire or electric shock. Thanks to the IP20 degree of protection, it is resistant to touch and dirt – which increases its durability and reliability. The short-circuit breaking capacity at 230V of 10kA and at 400V of 15kA (Icu) ensures a quick and effective response in the event of a serious failure. Additionally, the rated impulse withstand voltage Uimp of 4kV increases resistance to transient overvoltages.
