Overcurrent circuit breaker, 1P, B characteristic, 6A, 25kA, AC | S301P-B6 2CDS381001R0065

Installation protection and safety of use

This single-pole circuit breaker from ABB's S301P-B6 series is a key element of electrical protection in every circuit. Designed to protect against the effects of overloads and short circuits, it provides reliable operation and long-lasting protection of the electrical installation. Characteristic B makes it ideal for circuits with loads with moderate inrush current, such as lighting or sockets. The rated short-circuit breaking capacity of 25kA guarantees effective disconnection of the circuit in the event of a serious failure.

Construction and application

This circuit breaker is used in AC/DC installations with a rated voltage of 240V. Its compact size – only 1 module wide – allows for efficient use of space in the distribution board. Mounting is on a TH35 rail, which simplifies and speeds up installation. The cross-section of the wires that can be connected to the circuit breaker is from 0.75 mm² to 25 mm² for multi-strand wires and from 0.75 mm² to 35 mm² for solid wires, which provides great flexibility when selecting wires. The IP20 degree of protection provides protection against accidental contact.

Key features and benefits

• Characteristic B: Provides fast tripping in case of overloads, protecting the installation from damage caused by long-term load.
• Short-circuit breaking capacity 25kA: Guarantees safe disconnection of the circuit in the event of a short circuit, minimizing the risk of fire and equipment damage.
• Compact dimensions (1 module): Allows for efficient use of space in the electrical distribution board.
• Wide range of wire cross-sections: Allows you to connect wires of different thicknesses, adapting to the needs of a specific installation.
• Rated voltage 240V: Compatible with most standard electrical installations.
• Operating temperature 0-70°C: Possibility of use in various environmental conditions.
• Rated switching capacity Icu: up to 100 kA at 230 V - additional protection of the installation
• Power loss at 1W: Reducing energy consumption by the circuit breaker itself.
