Circuit breaker S 303 3P C 63A 6000A TX3 403551

Three-pole circuit breaker, from the S 303 TX³ series by Legrand, is a reliable protection for electrical installations against the effects of overloads and short circuits. Designed for easy installation and convenient wiring, thanks to the bottom fixing and terminal shields. The device is characterized by a high short-circuit breaking capacity, amounting to 6 kA at 400 V and 10 kA at 230 V, which ensures effective circuit protection.

Designed to work with various auxiliary equipment, such as auxiliary and signaling contacts, undervoltage and overvoltage release devices, and remote drives. Made in characteristic C, which means it reacts more slowly to short-term current surges – an ideal solution for circuits with receivers generating inrush currents, such as motors. The width of the device is 3 modules, which facilitates its integration with existing switchboards.

• Versatile application: Suitable for both home and commercial installations.
• Easy installation: Bottom fixing and terminal shields simplify the installation and connection process.
• Accessory compatibility: Possibility of expansion with additional functions thanks to compatibility with a wide range of Legrand TX³ accessories.
• High reliability: Compliance with IEC EN 60898-1 standard guarantees safety and performance.
• Durable construction: Mechanical endurance of 20,000 cycles ensures long-term operation.

The S 303 TX³ circuit breaker has a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. Suitable for operation at temperatures from -25°C to +70°C. The cross-section of the connection wires is from 1 to 35 mm², which provides flexibility in choosing the appropriate cables. The device is intended for mounting on a TH35 DIN rail. Characteristic C allows for safe operation of devices generating inrush currents during start-up.
