Circuit breaker S 301 1P D 10A 6000A TX3 403719

Safety and Reliability in Your Installation

Overcurrent circuit breaker S 301 1P D 10A is a safety element protecting the electrical installation against the effects of overloads and short circuits. Designed by Legrand, a renowned manufacturer of electrical installation solutions, it provides effective protection in both home and commercial installations. Characteristic D makes the breaker cope well with impulse loads, such as starting motors or devices with electronic power supplies.

Design and Installation – Simplicity for Professionals and Users

The S 301 breaker belongs to the TX³ series, which is characterized by a modern design and ease of installation. The lower latch and terminal covers facilitate and speed up the process of connecting wires. Installation is carried out on a standard TH35 rail, ensuring compatibility with most distribution boards. Compact dimensions (width 1 module, depth 44 mm) allow for optimal use of space in the switchgear cabinet.

Key Features and Benefits

• Short-circuit capacity: 6 kA at 230 V and 400 V – a guarantee of effective protection in the event of a short circuit.
• Characteristic D: Delayed response to short-term overloads, ideal for devices with high inrush current (e.g., motors, transformers).
• Rated current: 10 A – suitable for protecting circuits with medium load.
• Versatility: Possibility of cooperation with various auxiliary equipment (auxiliary contacts, release devices).
• Safety: Compliance with EN 60898 and IEC 60947-2 standards ensures a high level of safety.
• Flush mounting: Allows for aesthetic integration of the breaker into the existing electrical infrastructure.
• Degree of protection IP20: Protection against contact with fingers and solid objects larger than 12.5 mm.

The S 301 breaker operates at a rated voltage of 230 V AC (frequency range 50-60 Hz) and an insulation voltage Ui of 500 V. The rated impulse withstand voltage Uimp is 4 kV. The pollution degree is 2, which means that the device is intended for use in environments with a moderate degree of pollution. It is made of a single protected pole (total number of poles: 1) and does not have a simultaneously disconnecting N pole.
