Overcurrent circuit breaker, 2P, C characteristic, 2A, 10kA, AC | SU202M-C2 2CDS272337R0024

### Protection of installations and devices – reliable overcurrent switch

This two-pole overcurrent switch with C characteristic is a key element of every safe electrical installation. It provides effective protection of circuits against the effects of overloads and short circuits, minimizing the risk of damage and fires. It is a solution for both professionals and end users who value safety and reliability.

Functionality and application

The switch is designed to protect circuits in TN and IT systems. The C characteristic means that the switch reacts more slowly to short-term current surges, which is particularly important when connecting devices with motors or other loads with high inrush current – it will not unnecessarily disconnect when a refrigerator or washing machine is turned on. The rated current of 2A makes it ideal for protecting circuits with lower loads, such as lighting or sockets in residential premises. This switch finds application in residential, commercial and industrial buildings.

Key features and benefits

• High breaking capacity: Short-circuit capacity up to 15 kA at 400 V (according to IEC 60947-2) guarantees quick and safe disconnection of the circuit in the event of a short circuit. Additionally, the rated short-circuit breaking capacity Icn is 11.2 kA at 400 V (according to EN 60898).
• Wide voltage range: Designed to operate at a rated voltage of 440 V, ensuring compatibility with most electrical installations.
• TH rail mounting: Standard mounting on a TH rail simplifies and speeds up installation in the distribution board.
• Compact dimensions: Width of 2 modules allows for efficient use of space in the distribution board.
• Universal wires: Possibility to connect solid wires with a cross-section of up to 35 mm² and stranded wires up to 25 mm², provides flexibility during installation.
• Safety of use: Protection class IP20 protects against accidental contact, and overvoltage category III provides resistance to interference.
• Durable construction: Made of high-quality materials ensuring long-lasting and reliable operation at temperatures from -25°C to +55°C.
• Expandability: Compatible with additional accessories, allowing you to customize functionality to individual needs.

This switch meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, which confirms its high quality and safety of use. It is a solid and reliable solution for anyone who cares about the safety of their electrical installation.
