FAQ
Why do elevators need surge protection?
Elevators include sensitive controllers and drives that are vulnerable to overvoltages. A surge protection device for elevators prevents damage and downtime.
Where should KYSPD-7T1+2-3+1 be installed?
It should be installed in the distribution board that powers the elevator system.
Does it protect both phase and neutral conductors?
Yes, the 3+1 design makes this surge protection device for elevators effective for both phase-to-neutral and neutral-to-earth protection.
Can it be monitored remotely?
Yes, optional RC contacts allow integration into building management systems for elevator monitoring.
What standards does it meet?
IEC/EN 61643-11 for surge protective devices.
