PROTEK’s New range of Surge Protection devices (commonly known as Surge Guard) provides protection against surge currents and other instantaneous over voltages. Surge Guard is for use in circuits with a maximum operating voltage of 460v a.c. and operating frequencies of 50/60Hz.

Operation

The Surge Guard unit uses a metal oxide varistor and is designed to protect both the phase and neutral in the event of surge current. The unit offers a high resistance under normal load conditions and it is only when the device detects a high current that it ‘shunts’ the current to earth. This is done within less than 25 ms resulting in no damage to the circuit it is protecting.

Once the fault is cleared the device returns to its normal operation. The display window in the SurgeGuard unit is Green under normal operation and Red under a fault condition. The unit has a finite life and will display RED if the unit is no longer operational. At this point the plug in cartridge (SP1T2) should be replaced.
