Hager HAE410 4-Pole 100A Isolating Switch with Visible Break

The Hager HAE410 is a high-performance 4-pole isolating switch engineered for the secure disconnection of electrical circuits in demanding environments. With a rated current of 100A and support for 380-415V AC systems, this device provides a robust solution for industrial and commercial power distribution. Its primary design feature is a visible break mechanism, which allows operators to confirm the physical separation of contacts, thereby significantly reducing risks during maintenance and inspection procedures.

Advantages

This isolating switch offers exceptional reliability and safety for electrical infrastructure. The inclusion of a visible break mechanism provides clear visual confirmation of the circuit status, which is essential for meeting strict safety protocols in professional electrical installations. Its 4-pole configuration ensures comprehensive isolation of all phases and the neutral, providing a complete disconnect from the power source. Built with high-quality materials, the Hager HAE410 is designed to withstand the rigors of industrial use while maintaining consistent performance over its operational lifespan.

Suitable for

• Industrial electrical distribution boards
• Commercial building power management systems
• Maintenance isolation for machinery and equipment
• Main power supply disconnection in control panels

This switch may not be suitable for residential applications where space is limited or where the 100A rating exceeds the requirements of the installation. It is also not intended for use in environments with extreme moisture or corrosive atmospheres unless housed within an appropriately rated protective enclosure.

Key specifications

• Number of poles: 4
• Rated operational current: 100A
• Rated operational voltage: 380-415V AC
• Mechanism: Visible break

To use the Hager HAE410, ensure it is installed by a qualified electrician in accordance with local electrical codes. The device should be mounted within a suitable distribution board or enclosure. To isolate a circuit, rotate the handle to the designated off position and verify the physical separation of the contacts through the visible break window before commencing any maintenance work.

What to consider before purchase

• Verify that the 100A rating is appropriate for your specific circuit load
• Ensure the 4-pole configuration matches your electrical system requirements
• Check the dimensions of your enclosure to ensure sufficient space for installation
• Confirm that the voltage rating is compatible with your power supply

Usage recommendations

Always perform a voltage test using a calibrated multimeter after switching the device to the off position to confirm that the circuit is de-energized before touching any electrical components.
