## Long description

The Hager SBN399 is a professional-grade 3-pole modular switch disconnector engineered for the secure isolation of electrical circuits. Designed to handle a rated current of 125A and a voltage of 400V AC, this device serves as a critical component in both industrial and residential electrical distribution systems. It facilitates manual switching operations, allowing for the safe disconnection of power during maintenance or emergency situations, thereby ensuring the protection of personnel and equipment.
Advantages
This switch disconnector stands out due to its robust construction and high operational reliability, which are hallmarks of Hager engineering. Its modular design allows for seamless integration into standard DIN-rail distribution boards, saving space and simplifying the installation process. The device is built to withstand demanding electrical environments, providing consistent performance and long-term durability. By offering a clear visual indication of the contact position, it enhances safety during routine inspections and system servicing.
Suitable for
Industrial power distribution boards
Residential electrical panels
Commercial building energy management systems
Manual isolation of electrical circuits for maintenance
This device may not be suitable for applications requiring automatic circuit protection, such as overcurrent or short-circuit tripping, as it functions strictly as a manual switch disconnector. It is also not intended for use in high-voltage transmission networks or environments exceeding its specified voltage and current ratings.
Key specifications
Number of poles: 3
Rated operational current: 125A
Rated operational voltage: 400V AC
Mounting type: DIN rail
Switching type: Manual
To use the Hager SBN399, mount the device onto a standard DIN rail within your distribution board. Ensure that all electrical connections are tightened to the manufacturer's specified torque settings to prevent overheating or poor contact. Once installed, the switch can be operated manually using the front-facing toggle to connect or disconnect the power supply to the downstream circuit.
What to consider before purchase
Verify that the 125A rating is sufficient for your total circuit load
Ensure the 3-pole configuration matches your electrical system requirements
Confirm available space on the DIN rail within your distribution board
Check that the operating voltage of 400V AC is compatible with your installation
Always ensure that the power supply is disconnected before performing any installation or maintenance work on the switch disconnector. Regular inspections of the terminal connections are recommended to maintain optimal performance and safety.
