Isolating switch DPX3-I 250 4P 250A 420300

Isolator – safety and reliability in your installation

DPX3-I 250 isolator is a key element of any electrical installation, providing safe disconnection of circuits and enabling maintenance work. This device, manufactured by Legrand, is characterized by high reliability and durability, making it an ideal choice for both professional installers and end users. The design of this isolator has been created with ease of installation and intuitive operation in mind.

Functionality and application

DPX3-I 250 is a four-pole isolator, designed to operate in circuits with a voltage of 220-690V and a rated current of 250A. It can function as a main, safety and maintenance isolator, as well as an emergency switch. Thanks to the presence of auxiliary contacts (normally open, normally closed and changeover), it is possible to connect additional signaling or control devices. The rated operating power for AC-23 at 400V is 100kW, allowing its use in demanding industrial and commercial applications. Screw connection ensures a secure and durable connection of wires.

Characteristics and benefits

• Versatility: Ability to function as a main, safety, maintenance isolator and emergency switch – one device meets many needs.
• High short-circuit capacity: Rated short-time withstand current Icw at 1.7kA guarantees effective protection of the installation against the effects of short circuits.
• Safety: It has a locking mechanism that prevents accidental switching on of the isolator during maintenance work. The IP30 degree of protection provides protection against contact and ingress of solid objects.
• Flexibility: Option of mounting on a plate or in distribution boards increases the range of applications. The possibility of connecting an optional overvoltage release allows adaptation of the characteristics to specific installation requirements.
• Durability: Solid construction of the permanently mounted device ensures long-term trouble-free operation.
• Status indication: The presence of auxiliary contacts enables remote monitoring of the isolator status.
• Compatibility: Designed for installation in distribution boards, which facilitates integration with existing electrical infrastructure.

This isolator is not only a protective element, but also an investment in the long-term and safe operation of the entire electrical installation. Its solid construction and wide range of functions make it an ideal choice for both demanding installers and conscious end users looking for a reliable solution.
