Overcurrent circuit breaker, 2P, K characteristic, 3A, 10kA, AC/DC | S202M-K3UC 2CDS272061R0317

Electrical installation protection with ABB S202M-K3UC circuit breaker

This two-pole circuit breaker from ABB with K characteristic is a reliable protection for your electrical installation. Designed to protect circuits against overload and short circuit, it ensures safe operation and minimizes the risk of failure. It is characterized by a high short-circuit breaking capacity, reaching 10kA at 230V and 15kA at 400V, which guarantees an effective response in emergency situations.

This circuit breaker is ideal for both domestic and commercial and industrial applications. Its compact size (2 modules wide) makes it easy to install in standard distribution boards. Adapted to work in AC/DC circuits, it offers versatility and flexibility of application. The K characteristic means that the circuit breaker reacts a little slower to short-term current surges, which is particularly important when connecting devices with motors or other loads with high inrush current – this prevents unnecessary tripping.

Construction features and operating parameters

The S202M-K3UC circuit breaker has been designed with durability and reliability in mind. The IP20 degree of protection provides protection against accidental contact, and the ambient temperature range from 0 to 55°C allows operation in various environmental conditions. The rated impulse withstand voltage of 4kV guarantees resistance to overvoltages. The possibility of mounting additional equipment expands the functionality of the circuit breaker, adapting it to the individual needs of the installation. The cross-section of the wires that can be connected to the circuit breaker is from 0.75 mm² to 25 mm² for multi-strand wires and from 0.75 mm² to 35 mm² for single-strand wires. The energy limitation class is 3, which means a high ability to suppress short-circuit energy. Power losses are 2.48W. The rated insulation voltage Ui is 440V.
