Surge protection devices
Surges generated by lightning and disturbances on the grid causing even more damages to various types of electrical equipment, both in industry, offices and homes. Electronic components are the foundation for most modern devices, not just in the obvious - computers, control systems - but also in equipment where the use of electronics is not obvious.
Increased use of electronics increases vulnerability to power surges. The most common causes of surges are
- Direct lightning strike - even when there is a lightning rod
- Indirect lightning strike within a distance of up to 2 km from the point of impact
- Temporary surges in the grid caused by the example by closing/disconnecting large loads - transient
Over voltage surges causing damage to electronic components that cannot be repaired. The damage is not always visible and may be difficult to find. Replacement cost is usually high, in addition to the cost of lost production and downtime.
Cooper Bussmann offers surge protection for five application areas
- Surge protection devices for IEC applications
- Surge protection devices for photovoltaic applications
- Surge protection devices for wind power applications
- Surge protection devices for telecom applications
- Surge protection devices according to UL 1449 (introduced at the end of 2011)
All surge protection devices are designed on the same basic concept, a base unit with replaceable protection modules. The protection module is equipped with Easy-Id visual indicator that shows when the module needs to be replaced. Surge protective devices can be ordered with alarm contacts. The devices meet IP 20 ingress protection and are installed on 35 mm DIN rail.
