Circuit breaker S 303 3P C 6A 6000A TX3 403541

Electrical installation protection with Legrand S 303 circuit breaker

The S 303 3P C 6A circuit breaker is a reliable protection for electrical installations against the effects of overloads and short circuits. Designed for both professional installers and end-users, it provides safety and long-lasting functionality. The device is characterized by a compact design, easy mounting on a TH35 rail, and high breaking capacity.

Characteristics and application

The S 303 circuit breaker with characteristic C is particularly recommended for protecting circuits with receivers generating inrush currents during start-up, such as motors, transformers, or heating devices. Characteristic C allows for momentary exceeding of the rated current without unnecessary tripping, which minimizes the risk of false alarms and downtime of devices. The rated current of 6A makes it an ideal solution for circuits with medium power consumption. The three-pole design provides complete protection in three-phase systems.

Key features and benefits

• High breaking capacity: Rated breaking capacity up to 6 kA at 400 V and 10 kA at 230 V guarantees effective protection against the effects of short circuits.
• Flush mounting: Possibility of flush mounting ensures an aesthetic appearance of the installation and saves space.
• Easy installation: Bottom latch and terminal covers facilitate and speed up the installation and connection of wires.
• Compatibility with accessories: Possibility of cooperation with various auxiliary equipment (auxiliary contacts, signaling devices, releases) expands the functionality of the circuit breaker.
• Durable construction: Made of high-quality materials, ensuring long-lasting and reliable operation (mechanical durability: 20000 cycles).
• Safety: Energy limitation class 3 provides adequate protection in the event of an electric arc.
• Wide voltage range: Suitable for operation in networks with a rated voltage of 400 V (voltage range: 240-415 V).
• Versatility: Suitable for protecting various types of circuits in residential, commercial, and industrial buildings.

The S 303 circuit breaker is a solid and effective solution for anyone who values the safety and reliability of their electrical installation. Its versatility makes it suitable for use in many different construction projects.
