Overcurrent breaker S 301N 1P+N C 16 6000 A series DX3 407742

Reliable protection for electrical installations with the Legrand S 301N circuit breaker

The S 301N overcurrent breaker from the DX³ series is a protective device that effectively safeguards electrical circuits against overloads and short circuits. Designed for use in 230V installations, it ensures user safety and reliable operation. This model, with a rated current of 16A and characteristic C, is ideal for protecting lighting, socket, and electrical appliances with moderate inrush currents.

This single-pole breaker with connected neutral conductor (1P+N) features a compact design—occupying only one module on a TH35 rail. This makes it perfect for installation in space-constrained distribution boards. Its short-circuit breaking capacity of 6kA (per EN 60898) and 10kA (per IEC 60947-2) guarantees effective protection even during high short-circuit currents.

• Versatile application: Ideal for protecting lighting, socket, and electrical appliance circuits.
• Compact size: Occupies only one module on a TH35 rail, simplifying installation in tight distribution boards.
• High short-circuit breaking capacity: Ensures effective protection against the consequences of short circuits.
• Characteristic C: Allows for temporary overloads without unnecessary tripping—especially important for devices with motors or other components generating inrush currents.
• Expandability: Compatible with additional DX³ accessories such as auxiliary contacts or trip units.
• Safety and reliability: Complies with European standards (EN 60898 and IEC 60947-2).

The S 301N breaker is constructed from high-quality materials, ensuring durability and long-term operation. Installation is performed by snapping onto a standard TH35 rail, and conductor connections are made via screw or spring terminals (depending on version). Single-core conductor cross-sections range from 0.75 to 16 mm²; multi-core conductors from 0.75 to 10 mm². The breaker operates in an ambient temperature range of -25°C to +70°C, making it suitable for diverse environmental conditions. The IP20 protection rating ensures protection against accidental contact.
