HOMA AC switches are often used in applications where high currents under difficult switching circumstances have to be switched. Difficult circumstances are given i.e. in cases of low pure cosinus phi. These applications can be found in motors, inductive loads and capacitive loads. HOMA switches are worldwide known for switching of high currents.
HOMA switches can switch currents of up to 50.000A.
