Modular switch I-O-II 4P 125A HI406R

Modular switch for demanding applications

The 4-pole modular switch with a rated current of 125A is a reliable solution for switching circuits in electrical installations. Designed for use in both commercial and industrial buildings, it offers versatility and safety. Its construction allows for flexible use in various electrical network configurations.

Functionality and application

In addition to the functions of a safety switch and a maintenance switch, this switch also serves as a changeover switch – allowing you to change the power source or disconnect the receiver from the network. This makes it ideal for applications requiring frequent circuit switching, e.g. when servicing equipment or changing the power configuration. The ability to be used as a main disconnect switch further increases its versatility. Designed for mounting in distribution boards, it provides easy access and convenient operation. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

Key features and benefits

• High switching capacity: The rated operating power for AC-3 is 63 kW at 400 V, allowing it to handle even demanding loads.
• Safety: It has a rated short-time withstand current Icw of 2.5 kA and a rated conditional short-circuit current Iq of 50 kA, providing effective protection of the installation against the effects of short circuits.
• Flexible mounting: The ability to mount on a plate and in distribution boards makes it easy to integrate with existing electrical infrastructure.
• Durability and reliability: The solid construction of the permanently mounted device and the locking mechanism guarantee stable operation for a long time.
• Convenient operation: The short rotating handle provides comfortable and intuitive operation of the switch.
• Versatility: The function of a changeover switch, safety switch and main switch makes it a multifunctional device that can be used in various applications.
• Safety: Protection class IP20 provides basic protection against accidental contact with live parts.
• Screw connections: Ensure a secure and durable connection of wires to the switch.

This switch is characterized by a rated operating voltage in the range of 380-690 V and a rated continuous current Iu of 125 A. It also offers a high switching capacity – a rated operating power for AC-3 of 63 kW at 400 V and the ability to withstand a short-circuit current Icw of 2.5 kA and a conditional short-circuit current Iq of 50 kA. The device has 4 poles.

The HI406R switch is the optimal choice for installers looking for a reliable and versatile solution for switching electrical circuits and for end users who value safety and ease of use.
