Overcurrent circuit breaker, 1P, K characteristic, 1A, 6kA, AC | S201-K1 2CDS251001R0217

Reliable protection of electrical installations – ABB S201-K1 circuit breaker

This single-pole circuit breaker with K characteristic is a compact and effective solution for protecting electrical circuits. Designed for use in both residential and commercial applications, it provides effective protection against overloads and short circuits. Manufactured by the renowned ABB company, it guarantees high quality and reliable operation.

Functionality and application

The S201-K1 circuit breaker features a delayed thermal mechanism that protects against overloads at a rated current of 1A. Additionally, the electromagnetic release with K characteristic provides a quick response to short circuits, especially in circuits with high peak currents – ideal for protecting devices with motors or other loads generating high inrush currents during start-up. The rated breaking capacity of up to 6kA (at 230V and 400V) and 10kA (according to IEC 60947-2) ensures safety even in difficult working conditions.

Installation and compatibility

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and integration with existing electrical systems. Compact dimensions (width 1 module, depth 69 mm) allow for efficient use of space in the distribution board. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) or 25 mm² (stranded) provides flexibility in choosing the appropriate cables. The IP20 degree of protection protects against accidental contact.

Key features and benefits:

• K characteristic: Delayed tripping time in case of overload – ideal for circuits with motors and other loads generating high inrush currents.
• Breaking capacity: Up to 6kA at 230/400V AC and 10kA according to IEC 60947-2 – high resistance to the effects of short circuits.
• Compact dimensions: Only 1 module wide – saves space in the distribution board.
• Universal application: Residential, commercial and industrial buildings.
• Compliance with standards: Meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, which guarantees safety and reliability.
• Wide operating temperature range: From -25°C to +55°C – possibility of use in various environmental conditions.
• Expandability: Compatible with additional ABB System pro M compact accessories, allowing you to customize functionality to individual needs.
