DPX3 125 HP+RCD 4P 80 A 50 kA circuit breaker 423677

DPX3 HP+RCD Circuit Breaker – Reliable Protection for Your Installation

The DPX3 125 HP+RCD is a four-pole device combining the functions of an overcurrent and residual current device (RCD). It provides comprehensive protection for electrical circuits against overload, short circuit, and electric shock. This is a critical component for any safe and reliable electrical installation—whether in residential or industrial environments.

Functionality and Applications

This breaker features an exceptional short-circuit breaking capacity of up to 50 kA at 400 V, ensuring effective response during severe network disturbances. Its rated continuous current of 80 A makes it ideal for protecting high-load circuits. The integrated earth fault RCD protection further enhances user safety. With this device, you can be confident your installation is safeguarded against multiple hazards.

The DPX3 is suitable for use in:

• Distribution boards
• Lighting circuits
• Power supply for high-power electrical equipment
• Installations requiring high safety standards

Construction and Key Features

The DPX3 boasts a robust construction with a durable housing designed to resist mechanical damage. Installation is performed via bolted connections of main conductors, ensuring secure and stable electrical contact. An off-state indicator allows quick identification of whether the device has tripped and disconnected the circuit during a fault.

The overload trip setting range is 64 to 80 A, and the short-circuit trip level is 630 A, enabling precise adaptation to the specific requirements of the protected circuit. The absence of DIN rail mounting capability and motorized operation makes this a classic, reliable solution for demanding installers.

As a result, the DPX3 is easy to operate and highly dependable in performance.
