Modular power switch 4x63A HIM406

Universal power switch for home and industry

This modular HIM406 power switch from Hager is a reliable solution for switching electrical circuits. It is suitable for both home installations and more demanding industrial applications. It allows for safe and convenient switching between different power sources or circuits, which is particularly useful during maintenance, repairs or failures. The 4-pole (3P+N) design provides complete protection and control over the installation.

Functionality and application

The HIM406 switch is designed for mounting on a TH35 rail in distribution boards. Its main function is to manually switch electrical circuits, making it an ideal solution as a safety switch, maintenance switch or main switch. The ability to switch between three positions (I-0-II) increases its versatility. This allows the installer to easily configure it to the specific needs of the customer. It can be used in residential buildings, commercial facilities and industrial plants.

Key features and benefits

• High reliability: The device's construction ensures long-lasting and trouble-free operation.
• Versatility: Can be used as a safety switch, maintenance switch or main switch.
• Safety: Provides effective protection of the circuit against overload and short circuit — as with most circuit breakers in this class.
• Easy installation: Designed for quick mounting on a standard TH35 rail.
• Durability: Made of high-quality materials resistant to mechanical damage and environmental conditions.
• Suitable for working with high currents: Rated continuous current of 63A allows handling loads with significant power (up to 28 kW for AC-23).
• Locking mechanism: Prevents accidental switching on or off of the device during maintenance work.
• Solid connections: Screw connections ensure a secure and durable connection of the wires.

Technical parameters in practice

The HIM406 switch is characterized by a rated operating voltage in the range of 380-415V AC and the ability to withstand short-circuit currents up to 1.5kA. The rated operating power at 400V AC is as high as 41kW, which confirms its ability to handle demanding loads. The switching mechanism used allows for smooth and precise changes in the circuit state, and the compact dimensions (8 modules) facilitate installation even in tight distribution boards. The IP20 degree of protection provides basic protection against accidental contact and the ingress of solid objects larger than 12.5 mm.
