DPX3-I Disconnect Switch – Reliable Protection for Electrical Installations

The DPX3-I 125 A is a four-pole device designed for effective protection of electrical circuits with a rated current up to 125A. Manufactured by the renowned company Legrand, it ensures safe and efficient disconnection of power in case of overloads or short circuits. Its robust construction and high manufacturing quality guarantee long-term, fault-free operation in both industrial and commercial installations.

Functionality and Applications

This device is designed for DIN rail mounting (mounting rail not included) and offers versatility thanks to its rated voltage range of 220 to 690V. Equipped with two auxiliary changeover contacts, the disconnect switch can be integrated into remote control and circuit status signaling systems. It is suitable for use in public utility buildings, industrial facilities, and installations requiring frequent load disconnection. The complete enclosure design provides additional safety and protection against mechanical damage.

Key Features and Benefits

• High Current Rating: A continuous rated current of 125A enables protection of circuits with significant power demand.
• Wide Voltage Range: Operation from 220V to 690V enhances device versatility.
• Disconnection Indicator: Signals the open state of the circuit, facilitating fault identification and rapid power restoration.
• Robust Connections: Bolted connections ensure secure and durable wiring.
• Safe Operation: Lack of integrated earth fault protection requires additional protective measures, but provides greater control over the overall protection system.
• Two Auxiliary Changeover Contacts: Enable integration with automation and control systems, particularly beneficial in complex installations.
• IP30 Protection Rating: Protects against finger contact and ingress of solid objects larger than 2.5 mm – standard protection for devices installed in enclosures.

The DPX3-I disconnect switch is not only a protective element but also a critical component in ensuring the continuous operation of electrical installations. Its reliability and functionality translate into enhanced user safety and minimized risk of failure.
