Circuit breaker DPX3 250 HP EL S1 3P 250 A 70 kA 423243

Three-pole circuit breaker DPX3 250 HP EL S1 – reliable installation protection

This three-pole DPX3 250 HP EL S1 circuit breaker is part of the Legrand compact circuit breaker series, designed to protect electrical circuits with a rated current of up to 250A. Equipped with an S1 characteristic, it provides optimal protection against overloads and short circuits, making it an ideal solution for both industrial and commercial installations. The short-circuit breaking capacity of 70kA at 400V guarantees an effective response in the event of serious disturbances.

Design and functionality

The DPX3 circuit breaker features a solid fixed mounting design. It has two auxiliary contacts, which allow integration with control and signaling systems. Cable connection is made using bolted connections, ensuring a secure and durable connection. The tripping indicator allows for quick identification of the device status. The possibility of mounting a motor drive (optional) increases ease of use, especially in applications requiring remote control. The lack of a built-in short-circuit protection allows for flexible adaptation to the specifics of the installation – additional protection can be used if necessary.

Application and benefits

The DPX3 250 HP EL S1 circuit breaker is used in a wide range of electrical installations, such as:

• Main distribution boards: Provides central protection for the entire installation.
• Floor distribution boards: Protects individual circuits in the building.
• Industrial installations: Protects machines and equipment from damage caused by overloads or short circuits.
• Data centers: Guarantees a reliable power supply for critical equipment.

Using this circuit breaker translates to:

• High safety: Effective protection against overloads and short circuits minimizes the risk of fire and equipment damage.
• Reliability: Solid construction and high quality workmanship ensure long-lasting and trouble-free operation.
• Flexibility: The possibility of mounting a motor drive and the lack of a built-in short-circuit protection allow adaptation to individual needs.
• Ease of use: The tripping indicator facilitates diagnostics and quick identification of problems.
• Wide range of rated voltage: from 230V to 690V ensures compatibility with various power systems.
