Circuit breaker S 301 1P B 10A 6000A TX3 403355

TX³ series circuit breaker – reliable installation protection

The S 301 1P B 10A 6kA circuit breaker from the TX³ series is an electrical protection device that protects the installation and devices from the effects of overloads and short circuits. Thanks to its compact size and ease of installation, this device is suitable for both home and industrial installations. It is one of the basic devices ensuring the safety of electrical energy use.

Product features and application

The S 301 TX³ circuit breaker is characterized by a B characteristic, which means it is designed to protect circuits with low inrush current loads – e.g. lighting, sockets. Its single-pole design makes it ideal for protecting individual circuits. Mounting on a TH35 rail is quick and intuitive, and the ability to connect wires using screw terminals or comb busbars provides flexibility during installation. This circuit breaker works with additional auxiliary equipment, such as auxiliary contacts or undervoltage releases, which allows for expanding the functionality of the protection system.

• Overload protection: Protects wires and devices from damage caused by excessive current draw.
• Short-circuit protection: Immediately interrupts the circuit in the event of a short circuit, minimizing the risk of fire and failure.
• Compact size: 1 module width (17.8 mm) allows for efficient use of space in the distribution board.
• Easy installation: Quick mounting on a TH35 rail facilitates and speeds up installation work.
• Compatibility with accessories: Possibility of expanding functionality by mounting additional modules (auxiliary contacts, releases).
• Durable construction: Made of high-quality materials ensuring long life and reliable operation.

Technical parameters and compliance with standards

The S 301 TX³ circuit breaker meets the requirements of European standards EN 60898 and EN 60947-2, which guarantees its safety and effectiveness. It has a rated short-circuit breaking capacity (Icn) of 6 kA at 230 V and 6 kA at 400 V. Its rated voltage is 230 V, and the insulation voltage is 500 V. The energy limitation class is 3, which indicates its ability to suppress short-circuit energy. The IP20 protection degree provides protection against finger contact and the ingress of solid objects with a diameter of more than 12.5 mm.

This circuit breaker features a rated current of 10 A and a B tripping characteristic. The width of the device is 1 module, the rated voltage is 230 V, and the insulation voltage is 500 V. The energy limitation class is 3, and the IP20 protection degree provides basic protection against touch and the ingress of solid objects.

This circuit breaker is made of self-extinguishing materials with a flammability class of VO according to UL94, which further increases the level of safety.
