Hager SFT440 4-pole, 40A Centre Off Modular Changeover Switch with Top Common Point

Description

The Hager SFT440 4-Pole 40A Changeover Switch is the ultimate modular solution for three-phase power source management. Rated at 40A, this switch is designed for applications where a 63A switch (like the SF463) might be overkill, but where full 4-pole switching is still required for safety and compliance. It is widely used in commercial kitchens, small industrial plants, and for mobile 3-phase power units in the film and event industries.

The Centre Off (I-0-II) function is a non-negotiable for 3-phase machinery. By providing a distinct "0" position, the SFT440 ensures that the magnetic fields in motors have time to collapse before a new power source is connected, preventing mechanical stress and electrical surges. The Top Common Point configuration simplifies the busbar and wiring layout, keeping the panel tidy and maintenance-friendly.

With a 4-module width (70mm), the SFT440 is incredibly compact for a 4-pole changeover switch. This allows it to fit into smaller sub-boards or mobile enclosures where space is at a premium. Like all Hager SFT products, it features high-quality terminals that ensure a vibration-proof connection, which is vital for mining sites and portable equipment that is frequently transported.
