Three-pole circuit breaker DX3 16kA, 125A 409282

Reliable protection of electrical installations – Legrand DX3 three-pole circuit breaker

This three-pole overcurrent circuit breaker from the DX3 series by Legrand is a key element ensuring safety and reliability in every electrical installation. Designed for both home and professional use, it offers effective protection against overloads and short circuits. It is characterized by a high breaking capacity, which minimizes the risk of damage and ensures continuity of supply.

This circuit breaker, with a rated current of 125A and characteristic C, is ideal for circuits requiring protection against short-term current surges, such as those occurring when starting motors or devices with heating elements. The rated breaking capacity of 16kA at 400V and 32kA at 230V guarantees a quick and reliable response in the event of a failure. Mounting on a TH35 rail simplifies installation and integration with the existing system.

Solid construction and a wide range of applications

The DX3 circuit breaker is distinguished by its solid construction and high quality of workmanship. Its housing with a width of 4.5 modules provides compact dimensions, and the IP20 degree of protection protects against accidental contact. Adapted to work at temperatures from -25°C to 70°C, it will perform well in various environmental conditions. The possibility of connecting wires with a cross-section from 6mm² to 50mm² (multi-stranded) or 6mm² to 70mm² (solid) provides flexibility during installation.

• High breaking capacity: 16kA at 400V and 32kA at 230V – a guarantee of safety in the event of short circuits.
• Characteristic C: Optimal protection for circuits with devices generating surge currents (e.g. motors, transformers).
• Mounting on TH35 rail: Quick and easy mounting in the distribution board.
• Wide operating temperature range: From -25°C to 70°C – reliability in various conditions.
• Expandability: Compatible with additional Legrand accessories, allowing adaptation to individual installation needs.
• Compliance with standards: Meets the requirements of EN 60898 and IEC 60947-2 standards, ensuring safety and compliance with regulations.
• Mechanical durability: Provides more than 20,000 switching cycles, which translates into a long device life.
• Insulation voltage: Withstands insulation voltage up to 500V AC, which increases safety of use.

This circuit breaker is not only a protective element, but also an investment in the long-term and trouble-free operation of the entire electrical installation. Its solid construction and compliance with applicable standards make it an ideal choice for both professional installers and demanding end users.
