Reliable protection for electrical installations – Legrand S 301N circuit breaker

This single-pole circuit breaker with neutral pole (1P+N) is part of the DX³ series, designed to protect electrical circuits in residential and commercial buildings. Rated for operation at 230V, it provides effective protection against overloads and short circuits, minimizing the risk of equipment damage and fires. The B characteristic makes this breaker particularly recommended for circuits powering devices with high inrush currents, such as motors or transformers.

The S 301N breaker features a compact design—occupying only one module on a TH35 rail—allowing optimal space utilization in the distribution board. Its rated short-circuit breaking capacity of 6 kA (according to IEC/EN 60898-1) and 10 kA (according to IEC/EN 60947-2) ensures rapid and reliable response in case of hazardous conditions. Additionally, the IP20 protection rating safeguards against accidental contact with live parts.

Installation and Compatibility

The Legrand S 301N breaker is designed for mounting on a TH35 rail. It can be expanded with additional accessories from the DX³ series—such as auxiliary contacts or trip units—enhancing functionality and adapting it to individual installation requirements. The allowable conductor cross-sections range from 0.75 mm² to 16 mm² for single-core cables and from 0.75 mm² to 10 mm² for multi-core cables, ensuring broad compatibility with various wiring types.
