Circuit breaker S 303 3P B 10A 6000A TX3 403400

Three-pole circuit breaker series S 303 TX³

This circuit breaker, with a rated current of 10A and B characteristic, is a key element in protecting electrical installations from the effects of overloads and short circuits. Designed to work with devices with high inrush current, the B characteristic reacts with a delay to short-term current surges, preventing unnecessary tripping during the starting of motors or other loads. The rated short-circuit breaking capacity of 6kA at 400V ensures effective circuit protection.

Construction and mounting

The S 303 TX³ circuit breaker is designed for easy and quick installation. The possibility of flush mounting and mounting on a TH35 rail makes it perfectly suited to different types of installations. The compact width of 3 modules allows for optimal use of space in the distribution board. Terminal covers facilitate safe and convenient wiring. Additionally, the circuit breaker is compatible with a wide range of auxiliary accessories, such as auxiliary and signaling contacts, overcurrent and undervoltage releases, and remote drives – which increases its functionality and adaptation to individual needs.

Parameters and application

This circuit breaker is characterized by a rated voltage of 400V AC and an insulation voltage of 500V. Energy limitation class 3 provides adequate protection in the event of an electric arc. The degree of protection IP20 protects against finger contact, increasing safety. It will find application in residential and commercial building installations where reliable protection against overloads and short circuits is required. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. The rated impulse withstand voltage Uimp is 4kV, which confirms its resistance to overvoltages.
