Isolating switch DPX3-I 250 3P 250A 420299

DPX3-I isolator switch – reliable power disconnection

The DPX3-I 250 3P power switch is a device designed for safe and reliable disconnection of electrical circuits. It is suitable for both industrial installations and public buildings, providing effective protection against overload and short circuit. The device's construction, compliant with IEC 60947-3 standard, guarantees high reliability and long service life.

Functionality and application

DPX3-I is an isolating switch that can function as a main, safety or maintenance switch. This makes it a versatile element of the electrical installation, allowing for safe performance of maintenance work and emergency power outages. It has one normally open auxiliary contact, one normally closed and one changeover contact, allowing integration with control and signaling systems. The rated continuous current at 250A and the ability to operate at up to 690V AC make it suitable for use in circuits with high power consumption.

Key features and benefits

• Versatility: Can be used as a main, safety or maintenance switch – one device performs many functions.
• Safety: Provides effective isolation of the circuit on the supply side, minimizing the risk of electric shock during maintenance work.
• Durability: Made of high-quality materials, resistant to mechanical damage and environmental conditions.
• Easy installation: Designed for mounting on a plate or in distribution boards, making it easy to integrate with existing infrastructure. Screw connection ensures a secure connection of wires.
• Status indication: The presence of auxiliary contacts allows remote monitoring of the switch status and integration with alarm systems.
• Expansion options: The possibility of using an optional voltage release or motor drive adapts the device to specific installation requirements.
• Locking mechanism: Provides additional safety by preventing accidental switching on of the switch during maintenance work.

The DPX3-I switch is a solid and reliable solution for professionals and end-users looking for a safe and effective way to disconnect power in their electrical installations.
