A&T Enclosures are proud to now offer a range of ARC flash detection, protection and mitigation solutions. We are utilising leading manufacturers including Schneider, Arcteq and EE SA.

Incorporated in the manufacturing process or retrofit

At A&T Enclosures, professionalism and attention to detail are at the heart of everything we do — starting from the initial design phase. Our technical expertise enables us to integrate advanced ARC detection and protection into your new designs, while also offering retrofit solutions to upgrade existing equipment to meet the IEC 60947-9-2 standard.
We offer a complimentary design service for retrofit applications, ensuring your equipment can be efficiently brought up to the latest IEC standards. For retrofit projects, we prioritise minimal downtime — with many installations and commissioning processes completed in under an hour.

Key advantages of an ARC Guardian Retrofit:

  •  Vastly increased safety for electrical workers and operators, particularly during isolation and re-energising
  • Drastic reduction in collateral damage following an arc flash incident
  • Enables accurate mandatory Risk Assessments
    - Lowers class of ARC flash PPE requirements
    - Signage giving accurate working energy/incident levels of <8 cals/cm2 (Joules)
    - (Option for <1.2 cals/cm2)
  • Recommendation of class 2 arc flash PPE (Class 1 for <1.2cals/cm2 option)
  • Built-in ARC Flash Detection and Protection
    - An integrated, but independent protection, detection and isolation offering protection of 0.002 seconds plus breaker opening time /- 35-40ms (Conventional protection average 200ms if set correctly, which inevitably causes considerable collateral damage/destruction)
  • Improved resilience and reliability
    - Instantly reset, once fault removed or isolated from remaining g protected circuits Conforms to IEC60947-9-2-
