Hager SBN240 Modular Switch Disconnector 40A 2P

The Hager SBN240 is a professional-grade modular switch disconnector engineered for precise and reliable circuit control within electrical distribution systems. With a 40A current rating and a 2-pole configuration, this device is specifically designed to handle 400V AC electrical installations, providing a robust solution for both residential and commercial power management needs. Its compact modular design allows for seamless integration into standard distribution boards, ensuring that electrical circuits can be safely isolated for maintenance or emergency shutdown purposes.

Advantages

This switch disconnector offers exceptional reliability and durability, meeting the high standards expected from Hager electrical components. The device ensures secure isolation of electrical circuits, which is essential for protecting personnel during maintenance work. Its modular construction facilitates quick and easy installation on standard DIN rails, saving time and effort during assembly. Furthermore, the high-quality materials used in its construction ensure long-term operational stability and consistent performance under standard load conditions.

Suitable for

• Residential electrical distribution boards
• Commercial building power management systems
• Safe isolation of electrical circuits for maintenance
• Emergency power disconnection in small-scale installations

When it may not be suitable

This device is not intended for use in high-voltage industrial power grids exceeding its rated voltage capacity. It is also not suitable for applications requiring automatic circuit protection, such as overcurrent or short-circuit tripping, as it functions strictly as a manual switch disconnector.

Key specifications

• Rated current: 40A
• Number of poles: 2
• Rated operational voltage: 400V AC
• Mounting type: DIN rail
• Design: Modular

How to use

The Hager SBN240 should be installed by a qualified electrician in accordance with local electrical regulations. The device is designed to be snapped onto a standard DIN rail within a distribution board. Once mounted, the input and output cables should be securely connected to the respective terminals, ensuring that all connections are tightened to the manufacturer's specified torque. The switch is operated manually via the front-facing toggle to open or close the circuit as required.

What to consider before purchase

• Verify that the 40A current rating is sufficient for your specific circuit load.
• Ensure the 2-pole configuration matches your electrical system requirements.
• Confirm that there is adequate space on the DIN rail within your distribution board.
• Check that the 400V AC rating aligns with your installation's voltage.

Usage recommendations

Always ensure the power supply is completely disconnected before attempting to install or perform maintenance on the switch disconnector. Regularly inspect the terminals for tightness to prevent overheating and ensure optimal electrical contact.
