Surge Protection
Fundamentals

Hager SPD's protect electric and electronic equipment against transients, originating from lightning and switching transient sources.

The Hager System Approach

Transients can cause anything from the surge aging of
equipment, logic failures and downtime, to the complete
destruction of electrical components and the entire
electrical distribution system. Protection devices are
strongly recommended in sites that are exposed to
lightning, to protect sensitive and expensive electrical
equipment such as TV's, washing machines, Hi-Fi's,
PC's, VCR's, alarms etc...
Advantages
  • Replaceable cartridges for SPN115D/R,
    SPN140D/R & SPN165R,
  • Eliminates the risk of logic failures,
  • Does not disconnect from supply when
    experiencing a transient over voltage.
Plug in cartridges
Available for all discharge current capacities
(65kA, 40kA, 15kA), for surge protective
devices type 2. Plug in cartridges make
replacement of the protection device, without
need to cut off the power supply.

Comprehensive range

For installations with a lightning rod or high risk areas.

For installations with risk from switching transients.

To protect very sensitive electronic equipment.

For the protection of the receiver against transient current surge vehicled by telephone lines.
