Isolating switch DPX3-I 160 4P 160A 420199

Isolating switch DPX3-I 160 4P – reliable power disconnection

This four-pole DPX3-I 160A isolating switch is a key element of any electrical installation, providing safe and reliable disconnection of circuits. Designed for use in industry, commercial and residential construction, it offers the versatility and reliability that professionals expect. Its solid construction and high technical parameters guarantee long-lasting and trouble-free operation.

### Functionality and application

The DPX3-I 160A switch is used to safely disconnect electrical circuits during maintenance, repairs or failures. It can function as an emergency switch, a safety switch and a renovation switch. Thanks to the possibility of mounting on a plate or in distribution boards, it can be easily integrated with the existing infrastructure. It has one normally open auxiliary contact and one changeover contact, allowing connection of switch status signaling or remote control. The built-in locking mechanism provides additional safety, preventing accidental switching on of the circuit during maintenance work.

### Key features and benefits

* **High short-circuit capacity:** The rated withstand current Icw is 1.7 kA, which ensures effective protection of the installation against the effects of short circuits.

• Wide voltage range: Designed to operate in circuits with a voltage of 220 to 690 V AC, making it a universal solution for various applications.

• High rated current: The rated continuous current Iu at 160 A allows for protection of circuits with high power consumption.

• Flexible mounting: The possibility of mounting on a plate or in distribution boards facilitates integration with the existing electrical infrastructure.

• Safety of use: The locking mechanism prevents accidental switching on of the circuit during maintenance work.

• Expandability: Optional overvoltage and undervoltage release devices allow the switch to be adapted to specific installation requirements.

• Durable construction: The permanently mounted device guarantees stability and reliable operation for a long time.

• Compliance with standards: Meets safety and quality requirements, ensuring compliance with applicable regulations.

Additionally, the possibility of using optional overvoltage and undervoltage releases increases the functionality of the device, allowing protection against irregularities in the network voltage. The rated operating power for AC-23, 400 V is 64 kW – this is important information when selecting the appropriate protection for specific energy consumers. Screw connection type ensures a secure and durable connection of electrical wires. Protection degree IP30 protects against accidental contact with live parts.
