Overcurrent circuit breaker, 3P, B characteristic, 25A, 10kA, AC | S203M-B25 2CDS273001R0255

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. Manufactured by the renowned ABB, it guarantees high quality and reliable operation.

This circuit breaker, with a rated current of 25A and a short-circuit interrupting capacity of up to 10kA (AC), is perfect for protecting circuits with medium loads. The B characteristic means that the circuit breaker reacts quickly to short circuits, but is more tolerant to short-term current surges – which is particularly important when connecting devices with motors or other elements generating surge currents.

• Versatile application: ideal for protecting lighting, socket outlets and other electrical devices in residential and commercial buildings.
• DIN rail mounting: thanks to its width of 3 modules, it is easy to mount in a distribution board.
• Safety confirmed by standards: meets the requirements of overvoltage category III and pollution degree 3, ensuring protection in difficult environmental conditions.
• Solid construction: the housing with a protection degree of IP20 protects against touch and ensures the durability of the device.

This circuit breaker allows connection of conductors with a cross-section from 0.75 mm² to 35 mm², providing great flexibility when choosing the appropriate cable. Designed to operate at temperatures from -25°C to 55°C, it will perform well in various climatic conditions. Additionally, the possibility of expanding with accessories allows you to adapt the functionality of the circuit breaker to individual installation needs. The rated short-circuit interrupting capacity Icn is 10kA at 400V and 230V, and Icu reaches even 15kA at 400V and 25kA at 230V (according to IEC 60947-2), which guarantees a high level of safety in the event of a failure.
