Three-pole circuit breaker DX3 16kA, 80A 409280

Three-pole switch for reliable installation protection

This three-pole circuit breaker from the S 310 series is a key element ensuring safety in every electrical installation. Designed to protect circuits against overloads and short circuits, it guarantees stable operation and long-term reliability. Manufactured by the renowned Legrand, model DX3 80A with characteristic C is a solid solution for both professionals and demanding users.

Functionality and technical parameters

This circuit breaker is characterized by a rated current of 80A and a short-circuit breaking capacity of up to 16kA at 400V, making it an ideal choice for installations with medium and high power. Characteristic C provides delayed tripping during short-term overloads, which is particularly important for devices with motors or other elements generating high starting currents – this avoids unnecessary tripping of the circuit during normal operation. The rated impulse withstand voltage of 4kV further increases resistance to sudden voltage surges.

• Wide range of applications: ideal for protecting lighting circuits, socket outlets and electrical appliances in residential, commercial and industrial buildings.
• Mounting on TH35 rail: enables quick and easy mounting in electrical distribution boards.
• Protection degree IP20: provides protection against accidental contact and dust.
• Wire cross-section: accepts solid wires with a cross-section of 6-70 mm² and stranded wires 6-50 mm², providing great flexibility when selecting wires.
• Operating temperature: trouble-free operation in a wide range of temperatures from -25°C to 70°C.
• Compliance with standards: meets the requirements of EN 60898 and IEC 60947-2 standards, guaranteeing safety and reliability.

Construction and mounting – for professionals

The DX3 circuit breaker is distinguished by its compact design with a width of only 4.5 modules, which allows for efficient use of space in the distribution board. Mounting is done on a standard TH35 rail, and the solid construction ensures durability and resistance to mechanical damage. The possibility of flush mounting further increases the aesthetic appeal of the installation. Additional equipment allows you to adapt the circuit breaker to the specific requirements of a given project. It is worth noting the high quality of materials used in production – they guarantee long-term and trouble-free operation of the device for many years.
