Overcurrent circuit breaker, 2P, K characteristic, 25A, 50kA, AC | S802S-K25 2CCS862001R0517

Overcurrent circuit breaker – reliable installation protection

This two-pole overcurrent circuit breaker with K characteristic is a solid solution for securing electrical circuits. Designed for demanding applications, it offers a high short-circuit breaking capacity, providing effective protection against overloads and short circuits. It is suitable for both building installations and more demanding industrial environments or renewable energy systems.

Features and application

The S802S-K25 circuit breaker is characterized by a rated current of 25A and a short-circuit breaking capacity of up to 50kA at 400V. The K characteristic means that the circuit breaker reacts more slowly to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high starting currents – this avoids unnecessary tripping of the circuit. A width of 3 modules makes it easy to mount in standard distribution boards. Protection class IP20 provides basic protection against contact and ingress of solid objects.

• Application: Ideal for protecting circuits with greater resistance to interference, such as lighting, sockets, heating devices or motors.
• Mounting: Designed for mounting on DIN rail – a standard solution in most electrical distribution boards.
• Breaking capacity: High short-circuit breaking capacity (50kA at 400V) guarantees the safety of the installation even in the event of serious failures.
• K characteristic: Ensures stable operation with devices generating high starting currents, minimizing the risk of false tripping.
• Versatility: Suitable for use in residential, commercial and industrial applications.

Parameters and construction

The circuit breaker has been designed with durability and reliability in mind. Its construction provides resistance to environmental conditions in the temperature range from -25°C to 60°C. Made of high-quality materials, it meets safety standards and has a rated insulation voltage Ui of 690V and a rated impulse withstand voltage Uimp of 8kV. The energy limitation class is 3 and the surge category is 4, which proves its high resistance to network disturbances. Power losses are 6.4W at a rated voltage of 400V and a frequency of 50-60Hz. The possibility of additional equipment allows you to adapt the circuit breaker to specific installation needs.
