SZ201-C25 overcurrent circuit breaker, 1P, C characteristic, 25A, 6kA, AC 2CDS251025R0254

Overcurrent circuit breaker – reliable protection for electrical installations

This single-pole circuit breaker with C characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and the installation itself. This is particularly important in circuits with receivers with high inrush current, such as motors or transformers. The C characteristic allows it to react more slowly to short current surges, so it tolerates starting such devices well.

The SZ201-C25 circuit breaker is designed to operate in AC systems with a voltage of 230V and a rated current of 25A. Its high short-circuit breaking capacity (6kA) guarantees safety even in the event of serious failures. Mounting on a DIN rail is quick and easy, which will be appreciated by installers. Compact dimensions (1 module width) allow for optimal use of space in the switchgear cabinet.

Design features and application

This circuit breaker is part of the SZ200 series from ABB, known for its reliability and compliance with safety standards. Designed for use in residential and commercial buildings, it is ideal for protecting lighting circuits, socket outlets and electrical appliances. Compliance with EN 60898-1 confirms its high quality and safety of use. The degree of protection IP20 means that it is protected against finger contact, which increases safety during operation.

• Wide connection range: The ability to connect solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm² provides flexibility during installation.
• Withstand to surge voltage: The rated impulse withstand voltage Uimp is as high as 4 kV, which increases resistance to disturbances in the electrical network.
• Wide operating temperature range: The circuit breaker retains its properties at temperatures from -25°C to +55°C, allowing it to be used in various environmental conditions.
• Expandability: Thanks to the possibility of additional equipment, the functionality of the circuit breaker can be adapted to specific installation needs.
• Rated insulation voltage Ui: 440V AC ensures safe operation in various electrical network configurations.
