Overcurrent circuit breaker, 1P, D characteristic, 25A, 6kA, AC | S201-D25 2CDS251001R0251

ABB Standard series overcurrent circuit breaker is a reliable protection for electrical installations, designed for both home use and commercial or industrial facilities. Model S201-D25, with a rated current of 25A and a short-circuit interrupting capacity of 6kA, effectively protects circuits against overloads and short circuits. Characteristic D provides delayed tripping, which is particularly important for loads with high inrush current, such as motors or transformers.

This single-pole circuit breaker with a width of 1 module, mounted on a TH35 rail, is used in installations with a voltage of 230V. Its compact dimensions (installation depth 69 mm) make it easy to install even in limited space. The rated short-circuit capacity Icn is 6kA at 230V and 10kA at 400V, which guarantees effective protection under various conditions. The circuit breaker meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, ensuring safety and compliance with applicable regulations.

Construction features and application

The S201-D25 circuit breaker is made of high-quality materials, which translates to its durability and reliability. The degree of protection IP20 means protection against finger contact, which increases safety. The cross-section of the connecting wires can range from 0.75 mm² to 25 mm² for multi-wire cables and from 0.75 mm² to 35 mm² for single-wire cables – this provides flexibility when choosing the appropriate cables for the installation. Power losses are only 3.1W, which translates to energy savings. Surge category III and rated impulse withstand voltage Uimp at 4kV provide resistance to interference and overvoltages in the electrical network. The ambient temperature in operating conditions is in the range of -25°C to +55°C, which allows it to be used in various environmental conditions.
