Overcurrent circuit breaker, 2P, B characteristic, 2A, 6kA, AC | S202-B2 2CDS252001R0025

Reliable protection of electrical installations – ABB S202-B2 circuit breaker

This two-pole circuit breaker with B characteristic is a key element of every safe electrical installation. Designed by the renowned company ABB, it provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. Its compact size (2 modules) makes it easy to install in distribution boards, and its versatility makes it an ideal choice for both professionals and demanding users.

Functionality and parameters tailored to your needs

The S202-B2 circuit breaker with a rated current of 2A is characterized by a fast response to overvoltages (B characteristic), which is particularly important in circuits with electronic devices sensitive to voltage fluctuations. The rated short-circuit breaking capacity of 6kA (at 400V) guarantees safety in the event of serious disturbances in the network. This capacity reaches even 10kA at 400V and 20kA at 230V according to IEC 60947-2. The circuit breaker is designed to operate at temperatures from -25°C to +55°C, making it suitable for use in various environmental conditions.

Installation and compatibility

Installation is on a DIN rail, which is standard in most electrical distribution boards. The circuit breaker is compatible with wires with a cross-section from 0.75 mm² to 25 mm² (multi-strand) and from 0.75 mm² to 35 mm² (solid). The degree of protection IP20 provides basic protection against accidental contact. The possibility of expansion with additional accessories increases functionality and adaptation to individual installation needs. It meets the requirements of overvoltage category III and pollution degree 3, which confirms its reliability and durability.
