Hager SBN432 Modular Switch Disconnector 32A 4P

The Hager SBN432 is a professional-grade 4-pole modular switch disconnector engineered for the secure isolation of electrical circuits. Designed for integration into both industrial and residential distribution boards, this device serves as a reliable manual control point for disconnecting power during maintenance or emergency situations. Its robust construction ensures consistent performance and durability in demanding electrical environments, providing a dependable solution for circuit management.

Advantages

This switch disconnector offers exceptional reliability and safety for electrical installations. Its modular design allows for seamless installation on standard DIN rails, making it highly compatible with existing distribution systems. The device is built to handle frequent manual switching operations while maintaining high electrical integrity, which significantly enhances the safety of maintenance personnel by ensuring a clear and reliable disconnection of the power supply.

Suitable for

• Residential electrical distribution boards
• Industrial power control panels
• Commercial building electrical systems
• Manual isolation of lighting and heating circuits
• Maintenance and repair safety procedures

When it may not be suitable

This device is not intended for use as a circuit breaker or for automatic overload and short-circuit protection. It does not provide thermal or magnetic tripping functions, meaning it cannot replace a standard MCB or RCD in a circuit protection scheme.

Key specifications

• Rated current: 32A
• Number of poles: 4
• Rated operational voltage: 400V AC
• Mounting type: DIN rail
• Switching type: Manual

How to use

The Hager SBN432 should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution board. Once installed, the device is operated manually via the front-facing toggle switch. To isolate a circuit, simply move the switch to the 'OFF' position, which physically disconnects the power supply to the downstream equipment.

What to consider before purchase

• Ensure the rated current of 32A is sufficient for your specific load requirements.
• Verify that the 4-pole configuration matches your circuit wiring needs.
• Confirm that there is adequate space on the DIN rail within your distribution board.
• Check that the device is compatible with the voltage levels of your electrical installation.

Usage recommendations

Always verify that the circuit is de-energized using a voltage tester before performing any maintenance work, even after switching the disconnector to the 'OFF' position.
