The Hager SBN425 is a high-quality 4-pole modular switch disconnector engineered for the secure isolation of electrical circuits. Designed for integration into distribution boards, this device provides reliable manual control over power supply, ensuring that circuits can be safely disconnected for maintenance or emergency purposes. With a rated current of 25A and an operating voltage of 400V AC, it serves as a dependable component for managing electrical distribution in various environments.
Advantages
This switch disconnector stands out due to its robust construction and adherence to strict safety standards, which are hallmarks of Hager electrical components. Its modular design allows for seamless installation on standard DIN rails, making it highly compatible with existing distribution board configurations. The device offers a clear and positive switching action, which minimizes the risk of accidental operation and ensures long-term durability even under frequent use. By providing a reliable physical break in the circuit, it enhances the overall safety of the electrical installation.
Suitable for
- Residential electrical distribution boards
- Commercial and industrial power control panels
- Manual isolation of lighting or heating circuits
- Maintenance-related circuit disconnection
This device may not be suitable for applications requiring automatic switching or remote control, as it is designed strictly for manual operation. It is also not intended for use in circuits exceeding its rated current capacity of 25A or voltage rating of 400V AC, as this could lead to equipment failure or safety hazards.
Key specifications
- Number of poles: 4
- Rated current: 25A
- Rated operating voltage: 400V AC
- Mounting type: DIN rail
- Design: Modular
To use the Hager SBN425, ensure it is mounted correctly on a standard DIN rail within a distribution enclosure. The device is operated manually via the front-facing toggle, which allows the user to switch the power supply on or off. Always verify that the electrical load connected to the switch does not exceed the specified 25A rating before commissioning.
What to consider before purchase
- Verify that the 4-pole configuration matches your specific circuit requirements.
- Ensure the 25A current rating is sufficient for the intended load.
- Confirm that the installation space in your distribution board accommodates a modular device.
- Check that the 400V AC rating aligns with your local power supply standards.
Usage recommendations: Installation should only be performed by a qualified electrician in accordance with local electrical regulations. Regularly inspect the switch for any signs of physical damage or loose connections to maintain optimal performance and safety.
