Hager SH363S 3-Pole Electrical Switch 63A 400V

The Hager SH363S 3-Pole Electrical Switch is a professional-grade component engineered for secure power distribution and manual circuit control in various electrical systems. Designed to handle a nominal current of 63A and an operating voltage of 400V, this switch provides a reliable solution for disconnecting power in both residential and industrial environments. Its durable construction and clear visual design ensure long-term performance and ease of operation during routine maintenance or emergency shutdowns.

Advantages

This switch offers exceptional reliability due to its robust build quality, which is characteristic of Hager electrical components. The 3-pole configuration allows for the simultaneous disconnection of three phases, ensuring comprehensive safety during maintenance tasks. Its ergonomic design facilitates smooth manual operation, while the distinct blue and grey color scheme allows for quick identification within a distribution board. The device is built to withstand standard electrical loads, providing a stable and secure connection that minimizes the risk of power interruptions.

Suitable for

• Industrial power distribution panels
• Residential electrical installations
• Manual circuit disconnection for maintenance
• Control of three-phase electrical equipment

When it may not be suitable

This switch is not intended for use in environments where automatic circuit protection, such as overcurrent or short-circuit tripping, is required, as it functions strictly as a manual disconnect device. It is also not suitable for outdoor installations unless housed within an appropriately rated weather-proof enclosure.

Key specifications

• Number of poles: 3
• Nominal current: 63A
• Rated voltage: 400V
• Frequency: 50-60 Hz
• Color: Blue and grey

How to use

The Hager SH363S should be installed by a qualified electrician into a standard distribution board or enclosure. Ensure that the power supply is completely isolated before beginning the installation process. Mount the switch onto the DIN rail, ensuring a firm connection. Connect the input and output cables to the corresponding terminals, verifying that all connections are tightened to the manufacturer's specified torque settings. Once installed, the switch can be operated manually by toggling the handle to the desired position to connect or disconnect the circuit.

What to consider before purchase

• Verify that the 63A current rating is sufficient for your specific electrical load.
• Ensure the installation space is compatible with a 3-pole switch configuration.
• Confirm that the 400V voltage rating matches your system requirements.

Usage recommendations

Always perform a functional test after installation to ensure the switch operates smoothly and effectively disconnects the power supply. Regularly inspect the terminals for any signs of heat or loose connections to maintain optimal safety and performance.
