Overcurrent circuit breaker, 2P, K characteristic, 2A, 25kA, AC | S302P-K2 2CDS382001R0277

Protection of installations and devices – reliable ABB circuit breaker

This two-pole circuit breaker from ABB with K characteristic is a key element of protection in every electrical installation. Designed to protect circuits against the effects of overloads and short circuits, it ensures safe use and longer life of connected devices. The K characteristic means that the circuit breaker reacts relatively slowly to short-term current surges, which is particularly important for devices with motors or other elements generating high starting currents. This avoids unnecessary tripping of the circuit during normal operation.

Solid construction and high performance

This circuit breaker is characterized by a high short-circuit breaking capacity – as much as 25 kA at 400V, which guarantees effective protection even in the event of serious disturbances in the network. The rated current of 2A makes it ideal for protecting circuits with lower power consumption, such as lighting or sockets in office spaces. Compact dimensions (width 2 modules, depth 69 mm) allow for easy mounting in standard electrical distribution boards. Made of high-quality materials, it meets stringent safety standards and ensures long-lasting, trouble-free operation.

Key features and applications

• K characteristic: Delayed reaction to short-term overloads – ideal for circuits with motors and other loads generating high inrush currents.
• Short-circuit breaking capacity: 25 kA at 400V – high effectiveness in the event of serious disturbances.
• Wire cross-section: Possibility to connect solid wires with a cross-section of 0.75-35 mm² and stranded wires 0.75-25 mm² – wide range of applications.
• Rated voltage: 415 V – compatible with most electrical installations.
• Protection degree IP20: Protection against finger contact – safe to use.
• Overvoltage category IV: Provides protection in installations with an increased risk of overvoltage.
• Width 2 modules: Compact dimensions facilitate mounting in tight distribution boards.

This circuit breaker is used both in home installations (lighting, sockets) and in commercial and industrial facilities where reliable protection against overloads and short circuits is required. It is a product aimed at both professional installers and end-users looking for a solid and safe solution to protect their electrical installation.
