PROTECTION THAT SIMPLY WORKS.
Whether caused by lightning strikes, switching operations in the network, or distant disturbances – surges occur faster than you think. Within microseconds, they can destroy equipment, erase data, or, in the worst case, cause fires.
ELTAKO surge protection devices keep everything safe and sound:
They detect dangerous voltage spikes at an early stage and safely divert them into the earthing system – before any damage can occur. The installation of such protection devices is mandatory in residential buildings. Standard IEC 60364-5-53 specifies exactly how surge protection devices must be professionally installed.
To ensure your installation is optimally protected, three coordinated protection levels are distinguished:
Type 1 – Primary Protection
Mandatory for buildings with external lightning protection or in exposed locations. Safely diverts extremely high lightning currents directly into the earthing system before they can cause damage.
Our products:
Combined arresters Type 1+2 – MUA-30, MUA-50,
MUA-100
Type 2 – Intermediate Protection
The standard level of protection for all buildings (mandatory according to IEC 60364-4-44). Absorbs surges caused by distant lightning strikes or switching operations and keeps the building’s installation clean.
Our products:
Combined arresters Type 1+2 – MUA-30,
MUA-50, MUA-100
Pure Type 2 arrester – MUA-20
Type 3 – Fine Protection
Additional device-level protection for particularly sensitive electronics. Captures any residual surges not fully eliminated by Type 1 or Type 2 devices. Always used as a supplement, never on its own.
CONCLUSION:
Surges happen faster than you think – and can cause considerable damage.
With the right arresters, you’re fully protected: from primary protection (Type 1) to intermediate (Type 2) and fine protection (Type 3) – all tailored to your safety requirements. ELTAKO delivers the complete package – well thought out, compliant with standards, and developed for true professionals.
