Overcurrent circuit breaker, 2P, B characteristic, 63A, 6kA, AC | S202-B63 2CDS252001R0635

Reliable protection of electrical installations – ABB S202 series circuit breaker

This two-pole circuit breaker from ABB’s S202 series is a key element in protecting every electrical installation. Designed to protect against overloads and short circuits, it ensures safety and reliable operation. It is characterized by a high short-circuit breaking capacity – up to 6kA at 400V, making it an ideal choice for both home and commercial installations.

This circuit breaker has a B characteristic, which means it is particularly well suited for protecting circuits with receivers with high inrush currents, such as motors or transformers. This avoids unnecessary tripping when starting devices, while effectively responding to real threats.

Construction and practical application

Made of high-quality materials, the S202 circuit breaker is characterized by durability and resistance to environmental conditions. Its compact size – only 2 modules wide – allows for easy installation in electrical switchboards with limited space. The wire cross-section from 0.75 mm² to 35 mm² (solid) and 0.75 mm² to 25 mm² (stranded) ensures compatibility with various types of wires used in electrical installations.

This circuit breaker finds application in a wide range of installations:

• Lighting installations: Protection against overloads caused by too many connected light points.
• Electrical outlets: Protection against short circuits resulting from damage to devices connected to the outlets.
• Heating circuits: Protection against overloads caused by prolonged operation of heating devices.
• Electric motors: Thanks to the B characteristic, it provides protection against overloads during motor start-up.
• **Installations in residential, commercial and industrial buildings.

Key features and parameters for professionals

The S202-B63 circuit breaker meets stringent safety standards (overvoltage category III, limitation energy class III, pollution degree 3) and has a rated short-circuit breaking capacity Icn of 6kA at 400V and Icu of 10kA at 400V (according to IEC 60947-2). The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV. Power losses are 9.6W at a rated current of 63A and a frequency of 50 to 60 Hz. The IP20 degree of protection provides basic protection against accidental contact. The possibility of additional equipment allows the circuit breaker to be adapted to the specific requirements of a given installation.
