Hager SFT240 2-pole, 40A Centre Off Modular Changeover Switch with Top Common Point

Description

Stepping up in power, the Hager SFT240 2-Pole 40A Changeover Switch is designed for higher-demand single-phase circuits. With a 40A rating, this switch is the ideal choice for tradies installing manual transfer systems for large residential backup generators or for industrial equipment such as coffee roasters and commercial ovens. The Centre Off position (I-0-II) is essential for these applications, providing a physical and electrical break that protects sensitive electronic controllers from source-to-source transients.

The SFT240 follows the Top Common Point layout, ensuring it fits naturally into Australian wiring standards where the common connection is typically at the top of the device. Despite its higher amperage, it maintains a compact 2-module width (35mm), allowing for significant current-handling capacity without requiring a massive footprint in the distribution board. This makes it an excellent choice for retrofitting backup power capabilities into existing boards with limited space.

Durability is at the core of the SFT240. It is rated for 25,000 electrical cycles at its full 40A load, ensuring it can handle the startup currents of heavy machinery or large motors. Compliant with AS/NZS 60947 standards, it provides the reliability and safety certification that professional electricians and mine site managers demand.

• High 40A Capacity: Suitable for larger single-phase loads and generator backups.
• Double Pole Protection: Switches Active and Neutral for total source isolation.
• Centre Off Position: Critical for protecting equipment during manual transfers.
• Industry Standard Layout: Top common point for ease of installation.
• Robust Performance: High electrical durability under full load.
