Overcurrent circuit breaker, 2P, K characteristic, 8A, 10kA, AC/DC | S202M-K8UC 2CDS272061R0407

Universal protection for AC and DC installations

This two-pole circuit breaker with K characteristic is a reliable solution for protecting electrical circuits. Adapted to work in both alternating current (AC) and direct current (DC) installations, it provides effective protection against overloads and short circuits. The rated current of 8A makes it ideal for securing circuits with medium loads, and the high short-circuit breaking capacity – up to 10 kA – guarantees safety in the event of a failure.

Design and application

The S202M-K8UC circuit breaker belongs to the S200M UC series from ABB, which is highly regarded by professionals. The design based on a DIN rail facilitates mounting in electrical switchboards. The K characteristic means a delayed tripping time of the circuit breaker, which is particularly important in the case of loads with high inrush currents, e.g. electric motors or transformers. This ensures that the circuit breaker does not trip unnecessarily during short-term voltage surges, while still providing effective protection in the event of a real hazard.

Key features and benefits

• Versatility: The ability to use in AC and DC installations increases the range of applications.
• High short-circuit breaking capacity: 10 kA at 400V and 15 kA at 230V ensures the safety of the installation and devices.
• K characteristic: Delayed tripping time protects against false tripping caused by inrush currents.
• Compact dimensions: A width of only 2 modules allows for efficient use of space in the switchboard.
• Solid construction: Ensures long-lasting and reliable operation in various environmental conditions (operating temperature from -25°C to +55°C).
• Safety: Compliance with EN 60898 and IEC 60947-2 standards guarantees a high level of safety.
• Wire cross-sections: Possibility to connect solid wires with a cross-section from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm².
• Degree of protection IP20: Protection against contact with live parts.
