DPX3-I 125HP+RCD 4P 125 A disconnect switch 423187

DPX3-I Disconnect Switch – Reliable Protection for Electrical Installations

This disconnect switch is a comprehensive solution for protecting electrical circuits, combining the functions of a circuit breaker and a residual current device (RCD). Designed for use in installations with a rated voltage ranging from 220 to 690 V, it provides effective protection against overloads, short circuits, and electric shock. Its four-pole construction and rated current of 125 A make it ideal for safeguarding demanding circuits.

Functionality and Design

The DPX3-I disconnect switch features a built-in residual current device (RCD) protection that further enhances user safety. It includes two changeover auxiliary contacts, enabling integration with control and signaling systems. Main circuit connections are made via bolted connections on the front panel of the device. The IP30 protection rating ensures protection against accidental contact and ingress of solid objects.

• Integrated RCD Protection: Eliminates the risk of electric shock from leakage currents.
• Four Poles: Ensures complete protection of the entire circuit.
• Rated Current 125 A: Enables protection of circuits with higher power demand.
• Two Auxiliary Contacts: Allow connection of additional signaling or control devices.
• Switch with Off Indicator: Quick identification of device status – whether protection has tripped.
• Robust Construction: Device is manufactured as a complete unit in an enclosure, ready for installation.

Application and Installation

The DPX3-I disconnect switch is suitable for a wide range of electrical installations—from commercial buildings to industrial facilities. Its versatility and high reliability make it an ideal choice for both professional installers and end users seeking a safe and efficient solution for protecting their installations. Note that this device is not designed for mounting on TH or DIN TH rails; connections are made via bolted connections on the front panel.
