DPX3 circuit breaker 250 HP 4P 80 A 100 kA 423172

Reliable Protection for Electrical Installations – DPX3 250 HP Circuit Breaker

The DPX3 250 HP circuit breaker is an advanced solution providing effective protection for electrical circuits. Designed for demanding applications, it offers high reliability and operational safety. Its four-pole construction and rated current of 80 A make it an ideal choice for both commercial and industrial installations. A short-circuit breaking capacity of 100 kA ensures rapid response during faults, minimizing the risk of damage and downtime.

Functionality and Applications

This breaker is designed to protect against overloads and short circuits in circuits with a rated voltage range of 230 to 690 V. The trip characteristic allows precise adjustment to suit specific installation requirements: the overload setting range is 63–80 A, and the short-circuit setting range is 400–800 A. Equipped with an off-position indicator, it simplifies device status identification and fault localization. The breaker features bolted connections for main contacts, ensuring secure and durable wiring connections.

Key Features and Benefits

• High short-circuit breaking capacity (100 kA): Ensures fast and effective response during faults, protecting equipment and installations from damage.
• Adjustable trip settings: Enables precise tuning of the trip characteristic to match circuit specifics, optimizing protection performance.
• Four-pole design: Ideal for protecting three-phase power circuits.
• Off-position indicator: Facilitates diagnostics and rapid identification of the cause of tripping, reducing repair time.
• Robust construction: Fixed mounting ensures long-term stability and reliable operation.
• Optional motorized drive: Enables remote control of the breaker (available as a separate accessory).
• IP30 protection rating: Protection against contact and ingress of solid objects larger than 2.5 mm, enhancing user safety.
