MA3100 Series
Coordinated IEC 61643 Class I, Class II and Class III surge protection
The MA3100 range offers cost effective surge protection for applications described by IEC 61312, where the AC mains supply can carry
a partial share of the lightning surge current. Class I surge protectors (rated according to IEC 61643) are designed to carry up to 60kA
(10/350μs). Class II surge protectors are characterized by their ability to protect against 8/20μs impulses up to 45kA, possibly resulting
from the operation of a class I device. Finally Class III devices are used to protect individual pieces of equipment. An excellent example of a
class III device is the MA15.

Class III Surge Protection Device
The MA15 Series of surge protection devices has a unique ‘three stage’ combination of protection elements, that suppress conducted
RFI and voltage surges. The current elements are fi rst, surge clipping components to absorb transient surges that may otherwise
damage equipment, second a fi lter to suppress noise in the system and third, ‘ring’ suppression. The third of these prevents surges
causing the fi lter to ‘ring’ (oscillate) under low load conditions -- an effect that actually accentuates interference in most commercially
available fi lters.
The MA15 Series protects electronic equipment and computer networks against the effects of ‘noise pollution’ induced in power
supplies. MA 15 units ‘clean up’ the effects of industrial noise and surges caused by lightning, switching devices, thyristor controls,
transmission system overloads and power-factor correction circuits.
