V125 Arc Flash Relay

Basic Arc Fault detection for MV and LV power distribution

Schneider Electric’s arc flash detection units are versatile and independently operating devices for bay-based protection. They offer optimized and cost-effective solutions for panel builders and OEMs. Underlying this range is the knowledge, innovation, and reputation gained over nearly three decades. These fast and reliable devices reduce damage and protect installations.

V125 Arc Flash Relay
  • Features

    An arc flash is a mass of heat and pressure caused by a switchgear fault. Not only does it cause power outages, but it can also result in loss of business, extensive material damage, and can seriously jeopardize the safety of operational staff. Should a fault occur, arc flash protection minimizes burning time by quickly tripping the circuit breaker, cutting off the current feeding the arc. Short arc burning times are critical, especially when the arc develops during maintenance work on the switchgear, causing property damages. The unique arc fault functionality adds a new dimension to the total protection and reliability of the power distribution installation.

    Schneider Electric’s active arc flash protection units can detect arc flash faults and send a trip command to the circuit breakers within 1 ms to distinguish the fault.

    Benefits

    • Low investment costs and fast installation
      The pre-designed and documented protection schemes are cost-effective, fast to install and commission, and require low investment. One successful operation of the arc protection system provides an immediate return on the investment. 
    • Reduced loss of production
      The faster that arc protection operates, the less damage is caused by the arc fault, reducing the possible outage of the power supply. 
    • Easy installation in existing switchgear
      The product’s design allows for easy installation in existing switchgear. A number of accessories simplify and speed up installation in existing switchgear and electrical panels thanks to its compact design and installation kits. 
    • Reduced insurance costs
      The faster and better the protection system, the more generous the insurance terms and lower the cost should be.
