Isolating switch 4P ED2 400/4 004671279

The ED2 400/4 disconnecting switch is a reliable device designed for the safe disconnection of electrical circuits. It is a key element in electrical installations, providing the ability to switch off power for maintenance, repair work, or in emergency situations. The construction of this switch, based on proven ETI POLAM technology, guarantees high functionality and long-term operation.

Characteristics and application

The ED2 400/4 disconnecting switch is a four-pole device designed to operate with a rated voltage of up to 690V AC and 250V DC. A rated current of 400A makes it ideal for use in installations with medium and high power. The possibility of mounting on a plate provides flexibility in choosing the installation location. Therefore, the switch finds application both in industry and in commercial and residential construction – wherever a reliable and safe disconnection of circuits is required.

Screw connection ensures a secure and durable connection of the conductors. The device meets the PN-EN 60947-3 standard, which confirms its compliance with European safety standards. Its construction as a permanently mounted device ensures stability and reliable operation for a long time.

Advantages and technical parameters

The ED2 400/4 disconnecting switch stands out with a number of features that make it an optimal choice for professionals and end-users:

• High short-circuit resistance: The rated conditional short-circuit current Iq is as high as 70 kA, which provides effective protection of the installation against the effects of overvoltage and short circuits.
• Wide voltage range: The ability to operate in a voltage range from 230V to 690V AC and up to 250V DC makes the switch universal and can be used in various applications.
• Expandability: Optional motor drive and voltage release allow for remote control and additional protection of the installation.
• Functionality: It performs the functions of a main, safety, and maintenance disconnecting switch – one device replaces several traditional solutions.
• Safety: The IP20 degree of protection provides basic protection against accidental contact.
• Installation flexibility: Plate mounting facilitates integration with existing electrical infrastructure.

Additionally, it is worth mentioning the possibility of using mechanical locks (sliding MS, cable MLR/MLL or wire MW) to increase safety during maintenance work and the availability of direct or indirect manual drives for more convenient operation of the switch. The power supply can be connected from any side without affecting the technical parameters of the device.
