Power switch with thermal-magnetic trip unit DPX3 160 3P 25A 16kA 420001

Power switch for demanding installations

This three-pole power switch from the DPX3 series by Legrand is a reliable element for protecting electrical installations. Designed to protect against overloads and short circuits, it ensures safe use and long-term stability. A rated continuous current of 25A and a short-circuit breaking capacity of 16kA at 400V guarantee effective protection in the event of a failure.

Functionality and installation

The DPX3 160 switch is characterized by its versatile application – it is perfect for both commercial and industrial installations. Mounting on a TH rail is quick and intuitive, which translates into time savings during installation. Equipped with one normally open and one changeover auxiliary contact, it allows integration with control and signaling systems. A built-in undervoltage release further increases safety, protecting against the effects of voltage drops.

Key features and benefits

• High short-circuit breaking capacity (16kA): Ensures a quick response in the event of a short circuit, minimizing the risk of damage to the installation and equipment.
• Overload release setting range (20-25A): Allows precise adjustment to the load characteristics, preventing unnecessary tripping.
• Built-in undervoltage release: Additional protection against the effects of voltage drops, which is particularly important in installations sensitive to these disturbances.
• TH rail mounting: Quick and easy installation, saving time and installation costs.
• Solid construction: Guarantee of long-lasting and trouble-free operation even in difficult operating conditions.
• Protection degree IP30: Protection against contact with external factors, ensuring safe use.
• Expandability: Optional mounting of a motor drive allows remote control of the switch.
• Screw terminals: Provide a secure and durable connection of wires.
