Hager SBN325 Modular Switch Disconnector 25A 3P

The Hager SBN325 is a professional-grade 3-pole modular switch disconnector engineered for the secure control and isolation of electrical circuits. Designed for integration into distribution boards, this device provides a reliable means to disconnect electrical loads, ensuring safety during maintenance or system reconfiguration. With a robust construction typical of Hager components, it is built to withstand the demands of both residential and industrial power distribution environments, offering consistent performance and long-term operational stability.

Advantages

This switch disconnector stands out due to its high build quality and adherence to strict safety standards, which are essential for modern electrical installations. Its modular design allows for seamless installation on standard DIN rails, making it highly compatible with existing distribution board layouts. The device is specifically optimized for efficient load switching, minimizing energy loss and ensuring that electrical systems remain protected and manageable under various operational conditions.

Suitable for

• Residential electrical distribution boards
• Industrial power control systems
• Commercial building electrical infrastructure
• Isolation of electrical circuits for maintenance

This device may not be suitable for applications requiring higher current ratings exceeding 25A or for systems operating outside the specified 400V AC voltage range. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.

Key specifications

• Number of poles: 3
• Rated current: 25A
• Rated input voltage: 400V AC
• Mounting type: DIN rail

To use the Hager SBN325, it must be installed by a qualified electrician into a compatible distribution board. The device snaps onto a standard DIN rail, and electrical conductors are connected to the clearly marked terminals. Once installed, the manual toggle switch allows for the physical disconnection of the circuit, providing a visible and secure way to isolate power to downstream equipment.

What to consider before purchase

• Verify that the 25A rating is sufficient for your specific load requirements
• Ensure the 3-pole configuration matches your circuit design
• Confirm that your distribution board has sufficient space for a modular component

Usage recommendations

Always ensure the power supply is completely isolated before performing any maintenance or installation work on the electrical system. Regularly inspect the switch for any signs of wear or damage to maintain optimal safety standards.
