Overcurrent circuit breaker, 4P, C characteristic, 10A, 10kA, AC | S204M-C10 2CDS274001R0104

Overcurrent circuit breaker – reliable protection for electrical installations

This four-pole circuit breaker with C characteristic is a key safety element in every electrical installation. Designed to protect against overloads and short circuits, it ensures safe operation and long-term reliability. Designed for mounting on a DIN rail, it is ideal for both professional installers and end-users who value solid and proven solutions.

Construction and application

This circuit breaker belongs to the S204M series from ABB, characterized by its compact design and high-quality workmanship. The C characteristic means that the circuit breaker reacts more slowly to short-term current surges, which is particularly important for loads with motors or transformers – this prevents the device from unnecessarily switching off during start-up. The rated current of 10A makes it suitable for protecting circuits with medium power consumption. The rated short-circuit breaking capacity of 10kA (AC) guarantees effective protection in the event of serious disturbances in the network.

Key features and benefits

• High short-circuit breaking capacity: 10kA at 400V and 25kA at 230V ensures effective disconnection of the circuit in the event of a failure, minimizing the risk of damage and fire.

• C characteristic: Ideal for circuits with inductive loads (motors, transformers) where short-term inrush currents occur.

• Four-pole design: Provides complete protection for the entire circuit, including the neutral (N) conductor.

• Compact dimensions: A width of 4 modules makes it easy to install in switchboards with limited space.

• Wide operating temperature range: From -25°C to +55°C allows the circuit breaker to be used in various environmental conditions.

• Conductor cross-sections: The ability to connect solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm², provides installation flexibility.

• Safety and compliance with standards: Meets the requirements of EN 60898 and IEC 60947-2 standards, guaranteeing safe use and compliance with applicable regulations. Energy limitation class is 3.

Technical parameters in practice

Rated current: 10 A – determines the maximum current that the circuit breaker can conduct without tripping.

Tripping characteristic: C – defines the response time to overload – the C characteristic is suitable for devices with motors or transformers.

Short-circuit breaking capacity: 10 kA (400V AC) – determines the maximum short-circuit current that the circuit breaker can safely interrupt without damage.

Number of poles: 4 – provides protection for all phase conductors and the neutral (depending on the configuration).

Width: 4 modules – facilitates installation in standard modular switchboards.

The S204M-C10 circuit breaker is a solid and reliable solution for anyone who values safety and durability of electrical installations. Its versatility makes it suitable for use in residential, commercial and industrial buildings.
