Overcurrent circuit breaker, 2P, B characteristic, 20A, 25kA, AC | S302P-B20 2CDS382001R0205

Electrical installation protection with ABB S302P-B20 circuit breaker

This two-pole ABB S302P series overcurrent circuit breaker is a reliable protection for your electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe use and longer life of connected devices. Characteristic B makes it ideal for circuits with devices with moderate inrush current, such as lighting or sockets.

This circuit breaker is characterized by a high short-circuit breaking capacity – up to 25kA at 400V, which guarantees an effective response in emergency situations. Designed for operation in AC/DC installations, it offers versatility of application. A width of 2 modules allows for efficient use of space in the switchgear cabinet. Installation is simple and intuitive, and the solid construction ensures long-lasting and trouble-free operation.

#### Key features and benefits

* **Protection against overload and short circuit:** protects the circuit against damage caused by excessive load or short circuit – just like any standard circuit breaker.

* **Characteristic B:** provides a quick response to short-circuit currents, but allows for short-term overloads, which is important when starting some devices (e.g., motors).

* **High short-circuit breaking capacity (25kA):** guarantees effective disconnection of the circuit in the event of a serious failure.

* **Universal voltage (AC/DC):** possibility of use in both alternating and direct current installations.

* **Compact dimensions (2 modules):** saves space in the electrical switchgear cabinet.

* **Wide range of connectable conductors:** allows connection of conductors with a cross-section from 0.75 mm² to 25 mm² (stranded) and from 0.75 mm² to 35 mm² (solid).

* **Safety:** meets the requirements of IEC 60947-2 and EN 60898 standards, ensuring a high level of safety.

* **Durable construction:** made of high-quality materials, which translates into a long service life and reliable operation.

#### User parameters

The S302P-B20 circuit breaker has been designed with the requirements of both professional installers and end users in mind. Its rated current is 20A, and the rated insulation voltage Ui is 500V. Designed to operate in an ambient temperature from 0°C to 70°C, it will work in various environmental conditions. The IP20 degree of protection provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm – a standard for devices mounted inside switchgear cabinets. The rated impulse withstand voltage Uimp is as high as 6kV, which increases resistance to transient overvoltages occurring in the electrical network.
