Hager SFL125 1-pole, 25A Modular Changeover Switch with Bottom Common Point

Description

The Hager SFL125 1-Pole 25A Changeover Switch is a compact, space-saving solution for switching low-current single-phase circuits. What sets the SFL series apart is its Bottom Common Point configuration. This is particularly useful for electricians who prefer to use a busbar at the bottom of the distribution board or those working in tight enclosures where bottom-up wiring is more efficient. Occupying just 1 module (17.5mm), the SFL125 is the perfect fit for sub-boards in tiny homes, mobile workshops, or specialized industrial control panels.

Rated at 25A, this switch is commonly used for toggling between two different lighting circuits, switching between mains and a small inverter, or managing auxiliary power in caravans and RVs. Despite its small size, it is incredibly durable, boasting a mechanical life of 200,000 cycles. This exceeds the requirements of most residential applications, ensuring that even with frequent use in a commercial or event setting, the switch will perform reliably for years.

Hager has optimized the SFL125 for low power loss (only 0.90W), making it an energy-efficient choice for green building projects or off-grid solar setups where every watt counts. The screw terminals are designed to prevent "bird-nesting" of wires, accepting rigid conductors up to 16mmý for a solid, low-resistance connection.

• Space Efficient: Only 17.5mm wide (1 DIN module).
• Bottom Common Point: Optimized for specific busbar and wiring layouts.
• High Mechanical Life: 200,000 cycles for long-term reliability.
• Low Power Loss: Energy-efficient design for modern installations.
• Versatile Application: Ideal for caravans, RVs, and small sub-boards.
