Breakers and Switchgear - Low Voltage - Below 1 KV

Power circuit breakers should be upgraded with electronic trip units with arc flash safety features.  Power Precision rebuilds and modernizes low voltage power circuit breakers with new solid state trip relays with the following features:

  • LT, ST, INST, GF current trips
  • Voltage alarms and trips
  • Sluggish breaker detection
  • Self test feature with LED indication
  • Time stamping of events
  • Real time metering of A, V, KW, KVA, PF and more
  • Waveform capture
  • Network data communication of meter data and settings for central data collection and settings management
  • USB port for reading of metering data and programming settings without opening cubicle doors (additional door mounted display will also be available soon)
  • External maintenance mode selector for activation of faster trip settings for arc flash energy reduction during maintenance
  • Handheld plug-in trip controller for tripping of breaker from a distance

Arc flash safety can be improved by connecting new breaker trip units to a communication network.  The breakers can then be monitored online for the above metering parameters, breaker status, time stamps, breaker settings, alarms and central management of all breaker settings and maintenance data from a safe, central location.

Remote displays and handheld remote breaker controls can also be used to operate and program the breaker from outside the arc flash boundary.

LV Breaker Arc Flash Safety Features

For arc flash and worker safety, CSA recommends regular testing and maintenace of circuit breakers.  See information from CSA below.
