The Helios Fans RS 3+1+2 7.5 is a heavy-duty isolator switch designed for surface-mounted installation, housed in a durable polymer casing. It features a rotary actuator that allows for straightforward operation and secure locking.
This switch includes one auxiliary contact and two additional contacts specifically for connecting to motor protection devices such as TB/TP (TK/KL). The rotary switch can be padlocked in the “0” (OFF) position, offering three padlocking points for reliable protection against unauthorized use or accidental operation. Ideal for ventilation systems requiring enhanced safety and control, especially in setups with integrated motor protection features.
