Power switch with electronic trip unit with measurement function DPX3 250 EL+P 3P 100A 50kA 420465

Power switch – reliable protection of electrical installations

This three-pole DPX3 250 EL+P power switch with a rated current of 100A and a short-circuit breaking capacity of 50kA is a key element of every safe and efficient electrical installation. Designed for both domestic and industrial applications, it provides effective protection against overloads and short circuits, minimizing the risk of equipment damage and fires. An electronic release with measurement function further increases functionality and allows for precise control of operating parameters.

Functionality and application

This switch finds application in a wide range of installations, including heating systems, heat pumps, power tools, and in securing electrical circuits in residential and commercial buildings. The possibility of mounting on a TH rail facilitates installation and integration with existing systems. The built-in undervoltage release increases the safety of installation operation, protecting against voltage drops. The integrated auxiliary contact (1NO + 1NC) allows connection of additional signaling or control devices.

Key features and benefits

• High short-circuit breaking capacity (50kA): Ensures a quick and effective response in the event of a short circuit, protecting equipment from damage.
• Overload release setting range (40-100A): Allows you to adapt the switch characteristics to the specific needs of the installation and load.
• Electronic release with measurement function: Enables monitoring of installation parameters, which translates into greater control and optimization of energy consumption.
• Mounting on TH rail: Facilitates quick and easy installation in electrical switchboards.
• Trip indicator: Allows easy identification of the switch status – whether it has tripped due to overload or short circuit.
• Screw connection type: Provides secure and durable connection of wires.
• Protection class IP30: Protects against finger contact and against the ingress of solid objects with a diameter of more than 2.5 mm – standard protection for devices mounted inside switchboards.
• Expandability: Optional motor drive and additional auxiliary contacts allow you to adapt the switch to more advanced applications.
• Compliance with standards: The product meets stringent safety standards, guaranteeing reliable operation and long service life.

The continuous rated current is 100A, and the short-circuit breaking capacity is 50kA. The overload release setting range is between 40 and 100A.

The DPX3 250 EL+P switch is an investment in the safety and reliability of your electrical installation – both for professional installers and end users.
