Overcurrent circuit breaker, 3P, B characteristic, 10A, 10kA, AC | S203M-B10 2CDS273001R0105

Reliable protection of electrical installations with S200 series circuit breaker

This three-pole circuit breaker with B characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and people. It is indispensable in residential, commercial and industrial buildings where high reliability and safety are required.

This circuit breaker, with a rated current of 10A and a short-circuit breaking capacity of up to 10kA (AC), is designed to operate in installations with a voltage of 400V and a frequency of 50-60Hz. Its compact design – occupying only 3 modules on a DIN rail – allows for efficient use of space in the switchgear cabinet. The B characteristic means that the circuit breaker reacts quickly to an increase in short-circuit current, but at the same time tolerates short-term current surges during the starting of devices such as motors or transformers.

Solid construction and wide application

The circuit breaker is made of high-quality materials, which guarantees its durability and reliability even in difficult working conditions (ambient temperature from -25°C to +55°C). The IP20 degree of protection provides protection against accidental contact. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) or 0.75 mm² to 25 mm² (stranded) provides great flexibility during installation. The rated impulse withstand voltage of 4kV further increases the safety of the installation.

Compliance with EN 60898 and IEC 60947-2 standards confirms the high quality and safety of the product. Energy limitation class 3 and surge category III indicate its suitability for installations exposed to overvoltages. The circuit breaker has a rated short-circuit breaking capacity Icn of 10kA at 400V and Icu of 15kA at 400V, which ensures effective protection in the event of a short circuit.
