Surge Protection Meets IEC 61312
The MA3100 Series of IEC Class I, II and III surge products meets the standard described by IEC 61312, where the surge protector can carry a partial share of the lightning surge current. Models include the Class I lightning current arrester, Class II surge current arrester, and Class III surge protector, all rated according to IEC 61643.

The MA3100 Series:

• Class I – 60kA (10/350 ï�­s) DIN rail mounting, single pole width 18mm
• Class II – 45kA (8/20 ï�­s) DIN rail mounting, single pole width and multi-pole (single and three phase)
• Class III – RFI/EMI filtering in addition to excellent levels of surge protection, DIN rail mounting.

Class I lightning arresters offer a very high performance able to withstand the impact of a 60kA impulse - levels significantly higher than called for in IEC 61643 for a Class I device. Class II surge current arresters are designed to work both as standalone units and in a cascade coordination with a Class I lightning arrester. Class II devices are available in single width modules for maximum user flexibility, double width for all-mode protection on single phase systems and quad width modules for all-mode protection on 3-phase systems. Many Class II modules have remote monitoring capabilities as a standard feature. Voltage free, normally open, normally closed contacts can be used for a variety of monitoring tasks. Class III devices are used to protect a single instrument. The MA15 is an excellent example of a Class III protector.

The MA3100 Series incorporates a space saving, DIN rail mounted design. Even the powerful single pole module is only 18 mm wide. Each device is simply connected in parallel with the power system via a fused spur.
