Current Guard 3 & Current Guard Plus 3

The powerful Current Guard 3 and Current Guard Plus 3 help protect against utility power anomalies and lightning-induced transient surge events. Their compact and advanced design features thermally protected MOVs to eliminate overvoltage, safeguarding your equipment and capital investments.

Key benefits

  • Safeguard your capital investments - Help reduce operational downtime and maintenance costs
  • Absolute protection - CG3 and CGP3 protect sensitive equipment from failure by clamping transient voltage events as close as possible to nominal and redirecting them safely away from connected equipment
  • Enhanced safety - Thermal protection adds an additional level of protection by taking the SPD offline when reaching a certain temperature
  • Reliable performance- Single surge testing has been validated by an independent third party laboratory

 

Key features

  • Thermally protected MOVs
  • Multiple enclosure options
  • Compact and light-weight design
  • Dry relay contacts report SPD status remotely
  • Mounting kit to allow surface mounted or flush mounted (metal enclosure)
  • Audible and silence alarm indicate SPD status
  • Tri-color LED lights indicate SPDs operational status per phase.
  • Model CGP3 comes standard with surge event counter
  • Current Guard series is available in polycarbonate, powder-coated steel, and stainless-steel enclosure.

 

Technical specifications

  • 200kAIC short circuit rating for most available voltage configurations
  • Maximum surge current rating 50 kA to 200kA per mode
  • Nominal discharge current rating (I-n) 20kA for most available configurations
  • Operating frequency 47–63Hz (higher, larger caps?)
  • Connection method parallel to the electrical distribution system
  • Modes of protection All Modes (L-N, L-G, N-G, L-L)
  • Type 1 SPD with fault current rating (SCCR) 200kAIC – no upstream over-current protection device (breaker or fuse) required

 

Certification and standards

  • UL Listed 1449 4th edition for Type 1 and Type 2 SPD applications
  • Type 1 SPDs meet requirements for UL 96A
  • UL 1283 for Type 2 applications
  • IEEE C62.41.1, .2, C62.45
  • ROHs compliant
