PERGUNTAS FREQUENTES
Where should KYSPD-25T1-2P be installed?
At the service entrance or main distribution board, as the first stage of protection.
Does it support different earthing systems?
Yes, TN-S, TN-C, and TT systems are supported with correct wiring.
What backup fuse is required?
A maximum 315 A gL/gG fuse is recommended.
How do I replace the module?
The cartridge is pluggable. Isolate power, remove the old module, insert the new one, and restore power.
Is remote monitoring available?
Yes, optional RC terminals provide remote status signaling.
What is the ISCCR rating?
The device withstands up to 50 kA short-circuit current.
What happens if the module fails?
