Overcurrent circuit breaker, 2P, B characteristic, 10A, 6kA, AC | S202-B10 2CDS252001R0105

2-Pole Overcurrent Circuit Breaker – Reliable Protection for Electrical Installations

This two-pole overcurrent circuit breaker with B characteristic is a key safety element in any electrical installation. Designed for both domestic and commercial applications, it effectively protects circuits against overload and short circuits. A rated current of 10A and a short-circuit breaking capacity of 6kA guarantee its effectiveness in various operating conditions.

The S200 series circuit breaker from ABB is characterized by its compact design – it occupies only 2 modules on a DIN rail, making it easy to install even in crowded distribution boards. Its versatility stems from its ability to be used in installations with a voltage of 400V and a frequency of 50-60Hz.

Construction and Technical Parameters

The S202-B10 circuit breaker is designed for durability and reliability. The B characteristic ensures a quick response to short circuits, while the delayed thermal release protects against overloads resulting from prolonged load. This minimizes the risk of false tripping caused by short-term current surges, e.g., when starting motors.

The circuit breaker features a fast response to current increases thanks to the B characteristic, protecting wires and devices from damage in the event of an overload. It provides effective disconnection of the circuit during a short circuit thanks to its high short-circuit breaking capacity (6kA), minimizing the risk of fire and equipment damage. Compact dimensions – a width of 2 modules – facilitate installation in tight distribution spaces. A wide operating temperature range allows operation in the range of -25°C to 55°C, making the circuit breaker suitable for various environmental conditions. The ability to connect wires with a cross-section from 0.75 mm² to 35 mm² (solid) and from 0.75 mm² to 25 mm² (stranded) increases installation flexibility. Energy limitation class 3 provides adequate protection in the event of an electric arc.

Application and Compliance with Standards

The S202-B10 circuit breaker is used in a wide range of electrical installations:

• Protection of lighting circuits
• Protection of socket outlets
• Protection of low-power electrical appliances
• Domestic, office and industrial installations

The device meets the requirements of EN 60898-1 and EN 60947-2 standards, guaranteeing its safety and reliability. It also has an IP20 degree of protection, which protects against finger contact and access to hazardous live parts. The rated impulse withstand voltage is as high as 4kV, which further increases safety.
