The Hager HAC308 is a professional-grade 3-pole isolator switch engineered for the secure disconnection of electrical circuits. Designed to handle a rated current of 80A, this device is compatible with AC input voltages ranging from 380V to 415V. It serves as a critical component in power distribution systems, providing a reliable means of isolating electrical loads for maintenance, repair, or emergency shutdown procedures in both industrial and commercial environments.
Advantages
This isolator switch offers exceptional durability and operational reliability, meeting the rigorous standards required for professional electrical installations. Its robust construction ensures consistent performance under demanding conditions, while the 3-pole configuration allows for effective phase disconnection. By integrating this device into your electrical network, you enhance the safety of your infrastructure, facilitating quick and secure power isolation when necessary.
Suitable for
- Industrial power distribution panels
- Commercial building electrical systems
- Emergency shutdown control circuits
- Maintenance isolation for heavy machinery
This device is not intended for residential applications where lower current ratings are standard, nor is it suitable for direct current (DC) applications. It should not be used as a substitute for a circuit breaker or residual current device, as it does not provide overcurrent or short-circuit protection.
Key specifications
- Number of poles: 3
- Rated current: 80A
- Rated operational voltage: 380-415V AC
- Application: Industrial and commercial power distribution
To use the Hager HAC308, it must be installed within a suitable electrical enclosure by a qualified electrician. The device is typically mounted on a standard DIN rail or panel, depending on the specific installation requirements. Once installed, the switch is operated manually via the front-facing toggle to disconnect or reconnect the power supply to the downstream circuit.
What to consider before purchase
- Verify that the 80A rating matches your circuit requirements
- Ensure the voltage range is compatible with your power supply
- Confirm that the installation space meets the physical dimensions of the switch
- Check local electrical regulations regarding the use of isolator switches
Ensure that the isolator switch is clearly labeled to indicate which equipment it controls. Regular inspection of the terminal connections is recommended to maintain optimal electrical contact and prevent overheating.
