Overcurrent circuit breaker, 2P, K characteristic, 10A, 10kA, AC | SU202M-K10 2CDS272337R0427

Electrical installation protection with ABB SU202M-K10 circuit breaker

This two-pole circuit breaker from ABB, with a rated current of 10A and K characteristic, is a reliable element protecting electrical installations against overloads and short circuits. It provides effective protection of circuits, and its compact dimensions (2 module width) facilitate mounting in distribution boards. This circuit breaker is designed to operate in networks with a voltage of up to 440V and is characterized by a high short-circuit breaking capacity – up to 15 kA at 400V, which guarantees safety even in the event of large current flows.

The SU202M-K10 circuit breaker has been designed with durability and reliability in mind. Its housing is made of high-quality materials, resistant to mechanical damage and external factors. The IP20 degree of protection provides protection against accidental contact. Designed to operate in a wide range of ambient temperatures (-25°C to +55°C), it makes it a universal solution for various applications.

* K characteristic: provides a quick response to overloads and short circuits, but at the same time allows for short-term current surges, which is important when connecting devices with motors or other loads with high inrush current.

* Short-circuit breaking capacity: a high value of 15 kA (at 400V) guarantees the safety of the installation in the event of serious disturbances.

* Mounting: easy mounting on TH35 rail thanks to the standard width of 2 modules.

* Wire cross-sections: possibility of connecting solid wires with a cross-section of up to 35 mm² and stranded wires up to 25 mm², which provides great flexibility when selecting supply wires.

* Overvoltage category III: allows use in installations with a medium level of exposure to overvoltages.

* Power loss: Low power loss of 4.2 W contributes to the energy efficiency of the installation.

The SU202M-K10 circuit breaker is used in electrical installations of residential, commercial and industrial buildings where reliable protection against overloads and short circuits is required. It is ideal for protecting lighting circuits, socket circuits and electrical devices with a power adapted to the rated current of the circuit breaker (10A). Thanks to compliance with IEC 60947-2 and EN 60898 standards, it ensures a high level of safety and meets the requirements of modern electrical installations.
