Surge protection

MTL MA3100 Type 2 surge protector

The Crouse-Hinds series MTL MA3100 surge protectors are used for applications described by IEC 61312 where the surge protector could carry a partial share of the lightning surge current. The Class I devices, rated for 50kA (10/350µs), are deployed at the service entrance, followed by Class II rated devices at key power panels. Sensitive systems can then be locally protected by a Class III surge protector (such as an MTL MA15).
