Overcurrent circuit breaker, 1P, B characteristic, 20A, 10kA, AC/DC | S201M-B20UC 2CDS271061R0205

Reliable protection of electrical installations – ABB S201M-B20UC circuit breaker

This single-pole circuit breaker is a key element of every safe electrical installation. It provides effective protection of circuits against overload and short circuit, minimizing the risk of damage and fire. Characteristic B makes it ideal for protecting circuits with devices with moderate inrush current, such as lighting or sockets.

The S201M-B20UC circuit breaker is distinguished by its compact design – it takes up only one module on a TH35 rail, which makes installation easier even in crowded switchboards. Its high short-circuit breaking capacity (10kA at 230/400V) guarantees safety in the event of serious disturbances in the network. Made of high-quality materials, it ensures long-lasting and reliable operation.

• Fast response to overloads: Characteristic B ensures quick tripping in case of overloads, protecting wires and devices.
• High short-circuit breaking capacity: 10kA at 230V and 400V ensures safety in the event of serious failures.
• Compact dimensions: 1 module width makes it easy to install in tight switchboards.
• Wide range of applications: Ideal for lighting, sockets and other circuits with moderate inrush current.
• Solid construction: Ensures long-lasting and reliable operation in various environmental conditions (operating temperature from -25°C to 55°C).
• Versatility: Possibility of using solid (up to 35 mm²) and stranded (up to 25 mm²) conductors.

This circuit breaker meets the requirements of EN 60898 and IEC 60947-2 standards, which confirms its compliance with the highest safety standards. Energy limitation class 3 and surge category III provide additional protection of the installation against the effects of overvoltage. Protection degree IP20 protects against accidental contact. Power losses of only 2.33W minimize the impact on the energy efficiency of the installation.
