Circuit breaker S 301 1P B 20A 6000A TX3 403358

Reliable protection of electrical installations – Legrand S 301 TX³ circuit breaker

This single-pole circuit breaker with B characteristic is a key element of protection in every electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe use and long-term reliability. The S 301 TX³ model with a rated current of 20A and a breaking capacity of 6kA is a proven choice for both professionals and end users.

Functionality and installation

The TX³ series circuit breaker is distinguished by a well-thought-out design that simplifies installation and wiring. The lower latch and terminal covers significantly simplify the installation process, saving time and minimizing the risk of errors. Compact dimensions (width 1 module, installation depth 44 mm) allow for efficient use of space in the distribution board. Mounting is done on a standard TH35 rail.

• Easy installation: Thanks to the lower latch and terminal covers, installation is quick and intuitive.
• Compact dimensions: Occupies only 1 module in the distribution board, saving space.
• Versatility: Possibility of connection using comb or pin busbars increases installation flexibility.
• Expandability: Compatible with additional DX³ series auxiliary equipment, such as auxiliary contacts or release units.

Characteristics and technical parameters

The S 301 TX³ circuit breaker is characterized by a B characteristic, which means it is ideal for protecting circuits with receivers with high inrush current – e.g. electric motors or transformers. It provides a quick response to short circuits, while tolerating short-term current surges during device start-up. The rated short-circuit breaking capacity (Icn) is 6kA at 230/400V, which guarantees effective protection against damage to the installation.

• Rated current: 20 A – suitable for most standard circuits in residential and commercial buildings.
• B characteristic: Provides optimal protection for devices with high inrush current.
• Breaking capacity: 6 kA at 230/400 V – high effectiveness in the event of a short circuit.
• Rated voltage: 230 V AC – standard voltage in most electrical installations.
• Protection class: IP20 – protection against contact with fingers and against solid objects with a diameter of more than 12.5 mm.
• Insulation voltage: 500 V - ensures safe use in various environmental conditions.

This circuit breaker is a solid solution for anyone who values the safety and reliability of their electrical installation.
