Overcurrent circuit breaker, 1P, B characteristic, 2A, 6kA, AC | S201-B2 2CDS251001R0025

Installation and device protection – ABB S201-B2 circuit breaker

This single-pole circuit breaker from the ABB S200 series is a reliable protection for your electrical installation. Designed to protect against overloads and short circuits, it ensures safe use and longer life of connected devices. Characteristic B makes it ideal for circuits with inductive or capacitive loads, where short-term current surges occur – for example, in lighting circuits or sockets powering household appliances.

The S201-B2 circuit breaker combines compact size (only one module wide) with high performance. Mounting on a DIN rail is quick and intuitive, which will be appreciated by both professional installers and people performing electrical work themselves. The rated short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

Key features and applications

• Characteristic B: provides a quick response to overloads and short circuits, while allowing for short-term current surges – ideal for circuits with motors, transformers or fluorescent lamps.
• Rated current 2A: precisely matched to protect circuits with lower current consumption, e.g. lighting or sockets in office rooms.
• Short-circuit breaking capacity: high short-circuit breaking capacity (6kA at 230V, 10kA at 400V) ensures effective protection of the installation in the event of a failure.
• DIN rail mounting: standard mounting simplifies installation and replacement of the circuit breaker in existing distribution boards.
• Compact dimensions: one module width saves space in the distribution board.
• Wide operating temperature range: from -25°C to +55°C enables the use of the circuit breaker in various environmental conditions.
• Compliance with standards: meets the requirements of EN 60898-1 and EN 60947-2 standards, which guarantees safety and reliability.

This circuit breaker is used in electrical installations of residential, commercial and industrial buildings, where effective protection against overloads and short circuits is required. Its versatility makes it an ideal choice for both new installations and modernization of existing electrical systems. The wire cross-section from 0.75 mm² to 25 mm² allows connection of a wide range of wires of various types.
