Modular switch I-O-II 4P 63A HI403R

Modular switch for distribution boards – reliable circuit switching

This four-pole modular switch HI403R from Hager is a solid solution for switching electrical circuits in building and industrial installations. Designed for mounting on a DIN rail or mounting plate, it provides safe and convenient power switching. Its design allows operation in I-O-II systems, meaning the ability to switch between two circuits and disconnect the power.

### Functionality and application

The HI403R switch finds wide application in electrical distribution boards, where it serves as a main switch, safety switch, or maintenance switch. Thanks to the ability to switch between two circuits, it is ideal for applications where flexible power management is required. It can be used to switch power between the grid and a generator, or to isolate part of the installation for maintenance work. The locking mechanism increases safety by preventing accidental circuit disconnection.

### Key features and benefits

* **Versatility:** Changeover switch function (I-O-II) enables flexible power management.

* **Safety:** Acts as a safety and maintenance switch, providing protection during maintenance and emergency work.

* **Durability:** Rated continuous current of 63A and the ability to withstand short-circuit currents up to 2.5kA guarantee reliable operation even in harsh conditions.

* **Easy installation:** Designed for mounting on a DIN rail or mounting plate, making it easy to integrate with existing infrastructure.

* **Wide voltage range:** Ability to operate in networks with a voltage from 380 to 690V ensures compatibility with various electrical installations.

* **Solid connections:** Screw connection of the main contacts ensures a secure and durable connection of the wires.

* **Compliance with standards:** Meets the required safety standards, guaranteeing safe operation.

* **High connection capacity:** Connection capacity at 400V is as high as 41 kW, allowing operation of high-power loads.

### Technical parameters in practice

The HI403R switch is characterized by high technical parameters, which translate into its reliability and efficiency. The rated continuous current of 63A allows for safe power supply to devices with significant power. The ability to withstand short-circuit currents (2.5kA) protects the installation from damage in the event of a failure. In addition, the ability to operate in a wide voltage range (380-690V) makes the switch a universal solution for different types of electrical installations. The locking mechanism provides additional safety during use, minimizing the risk of accidental circuit disconnection during work or maintenance.
