Overcurrent circuit breaker, 3P, B characteristic, 32A, 6kA, AC | S203-B32 2CDS253001R0325

Reliable protection of electrical installations with ABB S203-B32 circuit breaker

This three-pole circuit breaker with B characteristic is a key element of every safe and reliable electrical installation. Designed by the renowned company ABB, it provides effective protection against overloads and short circuits in circuits with a rated current of 32A. Its compact dimensions (3 module width) make it easy to mount on a DIN rail, and the high short-circuit breaking capacity (6kA) guarantees safety in the event of a failure.

Functionality and application

The S203-B32 circuit breaker, thanks to its B characteristic, is ideal for circuits with devices with high inrush current – such as motors or transformers. The B characteristic means that the circuit breaker reacts faster to overloads, but tolerates short-term current surges during device start-up. This prevents unnecessary tripping of the circuit breaker and ensures continuity of power supply. The rated voltage of 400V and the frequency range of 50-60Hz make it a universal solution for most standard installations.

Key features and benefits

• High short-circuit breaking capacity: 6kA at 400V ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• B characteristic: Optimal for circuits with devices with high inrush current, prevents unnecessary tripping of the circuit breaker.
• Compact dimensions: 3 module width allows for efficient use of space in the switchgear cabinet.
• Compliance with standards: Meets the requirements of EN 60898-1 and EN 60947-2 standards, which guarantees safety and reliability.
• Wide operating temperature range: From -25°C to +55°C allows use in various environmental conditions.
• Possibility of additional equipment: Allows you to adapt the functionality of the circuit breaker to specific installation needs.
• Wire cross-sections: Accepts solid wires with a cross-section of 0.75 - 35 mm² and stranded wires 0.75 - 25 mm², providing flexibility when selecting power cables.

The S203-B32 circuit breaker is a solid and reliable solution for both professional installers and end-users looking for safe protection of their electrical installations. Its high quality workmanship and compliance with applicable standards guarantee long-lasting and trouble-free operation.
