Overcurrent breaker S 301N 1P+N C 25 6000 A series DX3 407744

Reliable Protection for Electrical Installations – Legrand S 301N Overcurrent Breaker

This single-pole overcurrent breaker with neutral pole, rated at 25A, is a critical component of any safe electrical installation. Designed by the renowned manufacturer Legrand from the DX³ series, it provides effective protection against the consequences of overloads and short circuits. Its compact dimensions (1 module width) enable efficient use of space in the distribution board.

The S 301N breaker features a Type C characteristic, making it ideal for protecting circuits with high inrush current loads—such as motors, transformers, or heating devices. Its delayed response to brief current surges minimizes the risk of unnecessary tripping during equipment startup. The rated short-circuit breaking capacity of 6 kA (per EN 60898) and 10 kA (per IEC 60947-2) ensures rapid and safe intervention in case of fault conditions.

Installation and Application:

The breaker is designed for mounting on a TH35 rail. Its versatility makes it suitable for both residential and commercial installations. It supports connection of single-core conductors with cross-sections from 0.75 mm² to 16 mm², and multi-core conductors from 0.75 mm² to 10 mm², ensuring compatibility with various cable types. The IP20 protection rating prevents accidental contact, enhancing user safety. Additionally, compatibility with accessories from the DX³ series allows customization to meet specific installation requirements.
