Overcurrent circuit breaker, 1P, D characteristic, 4A, 6kA, AC | S201-D4 2CDS251001R0041

Installation protection with D characteristic

The S201-D4 circuit breaker is a compact device used to protect electrical circuits against overloads and short circuits. It is characterized by high reliability and is designed for use in building and industrial installations. Its construction based on ABB technology guarantees long-term and trouble-free operation.

This single-pole circuit breaker with a rated current of 4A is designed for applications requiring a delayed response to short-term current surges. The D characteristic makes it ideal for circuits powering devices with high inrush current, such as motors, transformers or heating devices. This minimizes the risk of unnecessary tripping of the circuit during startup of these devices.

Construction features and application

The S201-D4 circuit breaker offers a rated short-circuit breaking capacity of up to 10kA at 230V and 400V, providing effective protection of the installation in the event of serious disturbances. This capacity is in accordance with IEC 60947-2 standards. Additionally, it has a short-circuit breaking capacity of 6kA according to EN 60898, which confirms its versatility and possibility of use in various types of installations.

• Width 1 module: Allows mounting in tight switchboards, optimizing space utilization.
• Wire cross-section: Supports stranded wires with a cross-section of 0.75 mm² to 25 mm² and solid wires from 0.75 mm² to 35 mm², providing flexibility in wire selection.
• Operating temperature: Adapted to operate in a wide range of ambient temperatures (-25°C to +55°C), allowing its use in various environmental conditions.
• Overvoltage category III: Provides protection against overvoltages in installations of category III, increasing safety of use.
• Protection degree IP20: Protects against touching with fingers and solid objects larger than 12.5 mm, providing a basic level of safety.
