Overcurrent circuit breaker, 3P, B characteristic, 80A, 6kA, AC | S203-B80 2CDS253001R0805

Reliable overcurrent protection for installation and device safety – ABB circuit breaker

This three-pole circuit breaker from ABB’s S203 series is a key element ensuring safety in any electrical installation. Designed to protect against the effects of overloads and short circuits, it guarantees uninterrupted power supply and minimizes the risk of damage. Characteristic B means the circuit breaker reacts quickly to current increases, which is particularly important in circuits with high-power devices or sensitive electronics. A rated current of 80A makes it ideal for protecting circuits with higher loads.

Construction and application – solidity and versatility

This circuit breaker is characterized by high quality and durability. Mounting on a TH35 rail allows for quick and easy installation in a distribution board. A rated short-circuit breaking capacity of 6kA at 400V and 10kA at 230V provides effective protection in the event of serious disturbances in the network. Designed for operation in AC installations with a voltage of 400V and a frequency of 50-60Hz, it will work in both residential and commercial buildings. A width of 3 modules allows for efficient use of space in the distribution board.

Key features and benefits for professionals and users

• Characteristic B: Ensures a quick response to current increases, protecting sensitive electronics and high-power devices. This is important for installers designing security systems tailored to specific customer needs.
• Short-circuit breaking capacity: 6kA at 400V and 10kA at 230V guarantees effective protection against the effects of short circuits, minimizing the risk of damage to the installation and devices. For the installer, this means confidence that the system meets the required safety standards.
• Mounting on TH35 rail: Enables quick and easy installation in a distribution board, saving time during installation.
• Width of 3 modules: Optimal use of space in the distribution board – important when designing compact solutions.
• Wire cross-section: Accepts solid wires with a cross-section of 2.5…50 mm² and stranded wires 4…35 mm², providing flexibility when selecting wires for the load.
• Overvoltage category III: Provides resistance to overvoltages occurring in the power grid, increasing system reliability.
• Degree of protection IP20: Protection against touching with fingers and solid objects larger than 12.5 mm – standard protection for devices mounted inside distribution boards.
• Ambient temperature: Operation in a temperature range of 0 to 55°C allows the circuit breaker to be used in various environmental conditions.
• Power loss: Low power loss of only 24.3W translates into energy savings during operation of the electrical installation.

The ABB S203-B80 circuit breaker is an investment in the safety and reliability of your electrical installation – both for professionals performing installations and for end-users who value peace of mind.
