Circuit breaker S 303 3P C 10A 6000A TX3 403543

Overcurrent circuit breaker from the S 303 series is an element used to protect electrical installations from the effects of overloads and short circuits. It is a three-pole device designed to work with circuits with a rated voltage of 400V. Characteristic C makes this circuit breaker perform well with loads with moderate inrush currents – typical for motors, transformers or certain types of lighting.

The breaking capacity of 6kA at 400V and 10kA at 230V ensures effective disconnection of the circuit in the event of a failure. Mounting is done on a standard TH35 rail, and the compact dimensions – only 3 modules wide – allow for optimal use of space in the switchgear cabinet. The gray (RAL 7035) finish blends in with the aesthetics of most installations.

This particular model, with a rated current of 10A, is a universal solution for both installers and end users. Simple installation and the ability to expand with DX³ series accessories (auxiliary contacts, release units) increase the functionality of the device. Protection class IP20 protects against accidental contact with live parts.

• Overload and short circuit protection: basic function ensuring the safety of the installation and connected devices.
• Characteristic C: ideal for circuits with receivers with moderate inrush currents – does not cause unnecessary tripping during short-term current surges.
• Compact dimensions: saving space in the switchgear cabinet thanks to a width of only 3 modules.
• Easy installation: quick and intuitive mounting on the TH35 rail.
• Expandability: compatibility with DX³ series accessories allows you to adapt the protective functions to individual needs.
• Compliance with standards: meets the requirements of IEC 60898-1 and IEC 60947-2 standards, guaranteeing a high level of safety and reliability.

This circuit breaker is made of high-quality materials, which ensures its durability and resistance to environmental conditions. It is a solid and reliable device that will last a long time, ensuring the safety of the electrical installation.
