## Summary description

The Legrand S304 is a high-quality 4-pole miniature circuit breaker designed for reliable electrical circuit protection. Featuring a C-curve tripping characteristic and a 63A rated current, it offers a 6kA breaking capacity. This device is essential for safeguarding electrical installations against overloads and short circuits in residential and commercial distribution systems.

## Long description

The Legrand S304 is a professional-grade 4-pole miniature circuit breaker engineered to provide robust protection for electrical distribution systems. This device is designed to monitor current flow and automatically disconnect the circuit in the event of an overload or short circuit, ensuring the safety of both the electrical installation and connected equipment. With its reliable construction and precise tripping mechanism, it serves as a critical component in modern residential and commercial electrical panels.
Advantages
This circuit breaker offers high operational reliability and durability, making it an excellent choice for demanding electrical environments. The C-curve tripping characteristic provides a balanced response, allowing for standard inrush currents while maintaining fast protection against faults. Its 4-pole configuration enables the simultaneous disconnection of all phases and the neutral, providing comprehensive isolation for three-phase systems. The compact design ensures efficient use of space within distribution boards, while the high-quality materials used in its manufacturing guarantee long-term performance and safety compliance.
Suitable for
Three-phase residential electrical installations
Commercial building distribution boards
Protection of lighting and power circuits
Industrial control panels with moderate power requirements
This device may not be suitable for applications requiring specific tripping curves, such as D-curve for high-inrush motors or B-curve for highly sensitive electronic equipment. It is also not intended for use in environments exceeding its 6kA breaking capacity or for systems operating outside of its rated 63A current capacity.
Key specifications
Number of poles: 4
Rated current: 63A
Tripping characteristic: C-curve
Breaking capacity: 6kA
Mounting type: DIN rail
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed to be snapped onto a standard DIN rail within an enclosure. Ensure that all wire connections are tightened to the manufacturer's specified torque settings to prevent overheating. Before installation, verify that the circuit load does not exceed the rated capacity of the breaker.
What to consider before purchase
Verify that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point
Ensure the 63A rating matches the requirements of the protected circuit
Confirm that a 4-pole device is required for your specific wiring configuration
Check the available space in your distribution board for a 4-module wide device
For optimal safety and longevity, regularly inspect the circuit breaker for signs of thermal damage or loose connections and ensure the distribution board remains free of dust and moisture.
