DPX3 125 HP 3P 80 A 50 kA circuit breaker 423647

The DPX3 125 HP breaker is a three-pole device designed to protect electrical circuits with a rated current of 80 A. It provides effective protection against overloads and short circuits, while its high breaking capacity—up to 50 kA at 400 V—ensures installation safety in the event of a fault.

This DPX3 series breaker is particularly suitable for installations requiring high reliability and resistance to disturbances. Thanks to adjustable settings for the thermal overload trip (64–80 A) and magnetic short-circuit trip (640–960 A), it can be precisely tuned to match the load characteristics. It features two auxiliary contacts, enabling connection of status signaling or control of other devices.

• Robust construction: The device is manufactured from high-quality materials, ensuring durability and reliability under demanding operating conditions.
• Versatile application: Suitable for protecting circuits in residential, commercial, and industrial installations.
• Safety: A rated short-circuit breaking capacity of 50 kA minimizes the risk of damage to the installation and equipment during a short circuit.
• Flexibility: Adjustable trip settings allow precise customization to the specific requirements of the protected circuit.
• Trip indicator: Enables rapid identification of the breaker’s status and potential fault causes.
• Easy installation: Equipped with screw terminals for straightforward wiring and mounting.

The DPX3 125 HP breaker has an IP30 protection rating, providing protection against finger contact and ingress of solid objects larger than 2.5 mm. Its design features a fixed-mount configuration; it does not support DIN rail or TH rail mounting, making it intended for specific applications requiring stable, permanent installation. Compliance with relevant standards ensures safe operation and reliable performance under varying working conditions. Note that the device is supplied with built-in protection—ready for immediate use after installation.
