Overcurrent circuit breaker S 301 1P D 63A 6000A TX3 403727

Reliable protection of electrical installations with S 301 TX³ circuit breaker.

This single-pole circuit breaker from the TX³ series by Legrand is a key element ensuring safety in every electrical installation. Designed to protect against the effects of overloads and short circuits, it guarantees stable and safe operation of circuits. It is characterized by high reliability and ease of installation, making it an ideal choice for both professional installers and end users.

### Functionality and technical parameters

The S 301 1P D 63A circuit breaker features a D characteristic, which means a delayed response to short-term current surges. This is particularly important when protecting circuits with devices with high inrush current, such as motors or transformers. The rated current of 63A and the breaking capacity of 6 kA (at 230V and 400V) ensure effective protection in the event of a failure. Additionally, the rated voltage of 230V and the impulse voltage withstand of 4 kV guarantee safety in various operating conditions.

* **Rated current:** 63 A – provides adequate protection for circuits with higher power demand.

* **Characteristic D:** delayed response to short-term overloads, ideal for devices with high inrush current.

* **Breaking capacity:** 6 kA at 230V / 400V – effectively interrupts the circuit in the event of a short circuit, minimizing the risk of damage.

* **Mounting:** TH35 rail – standard mounting simplifies installation in electrical distribution boards.

* **Protection degree IP20:** protection against touching with a finger and solid objects with a diameter greater than 12.5 mm.

### Design and advantages of the TX³ series

The TX³ series is a modern solution from Legrand, characterized by high quality workmanship and thoughtful design. These circuit breakers have a lower clip and terminal covers, which significantly facilitate installation and connection of wires. The possibility of additional equipment, such as auxiliary contacts or undervoltage releases, allows you to adapt the circuit breaker to individual installation needs. Compact dimensions (width 1 module, embedding depth 44 mm) allow for efficient use of space in the distribution board. Made of high-quality materials, it ensures the durability and reliability of the device for a long time.
