Overcurrent breaker S 301N 1P+N C 10 6000 A DX3 series 407740

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

This single-pole circuit breaker with connected neutral pole (1P+N) from the DX3 series is a critical protective element in any electrical installation. Designed to protect circuits with a rated current of 10A, it ensures effective operation during overloads and short circuits. Thanks to its C characteristic, this breaker handles impulse loads—such as motor startups—without unnecessary tripping.

Functionality and safety in one device

The S 301N breaker features a high short-circuit breaking capacity of up to 6 kA at 230 V (compliant with EN 60898) and 10 kA in accordance with IEC 60947-2. This ensures rapid and reliable disconnection during a short circuit, minimizing the risk of damage and fire. The rated impulse withstand voltage of 4 kV further enhances its resistance to sudden voltage surges.

The breaker’s design allows for flush-mounted installation, ensuring a clean and aesthetic installation. Additional accessories can be fitted to tailor the device to specific circuit requirements. The conductor cross-section range is 0.75 mm² to 16 mm² for single-core cables and 0.75 mm² to 10 mm² for multi-core cables, offering great flexibility during installation.

Technical specifications for professionals

The S 301N breaker is designed for easy installation and operation. With a width of just one module (18 mm), it enables optimal space utilization in distribution boards. The IP20 protection rating safeguards against finger contact and ingress of solid objects larger than 12.5 mm. Operation across a wide ambient temperature range (-25°C to +70°C) ensures reliable performance even under harsh conditions. Constructed from high-quality materials, it complies with EN 60898 and IEC 60947-2 standards, confirming its safety and reliability.
