NEO STS (1-2 Pole)

STATIC TRANSFER SWITCH / 32-120 A (1-2 Pole)


With Neo STS Static transfer switch loads are protected against critical environmental situations and mains power interference. Microprocessor control and the use of
thyristor static switches ensure continuous monitoring of the power supply sources and reduced switching times between the two sources in the event of a fault. The constant monitoring of the output current allows for the rapid identification of any short circuit currents in the consumers, preventing short
circuits from propagating to other loads. NEO STS  is equipped with thermal-magnetic protection for the two sources, ensuring rapid intervention in the event of faults .
NEO STS ensures switching times between the two power sources of less that a quarter of a cycle, both in the event of manual switching and in the event automatic switching triggered by a fault in the power source.
