Work safer around live switchgear with the Teledyne Flir IR Inspection Window (IRW-3C). It lets you inspect energised equipment while panels stay shut, and it helps reduce arc flash risk. Moreover, the broadband crystal passes short, mid and longwave IR, so one window suits many cameras.

Safety and compliance

You keep compliance in mind, and this window helps. It supports NFPA 70E work practices, so checks stay within safe limits. As a result, you can plan routes better, and you can finish more surveys in less time.

Construction and optics

The anodised aluminium frame resists corrosion, and the stainless steel option helps when mixed metals may react. The PIRma-Lock locknut holds the ring in place, and you do not need extra screws during install. In addition, illumination can pass through the window, and that aids aiming and focus.

Fit the 3-inch window through a 3.5-inch cut-out, and mount it on indoor or outdoor enclosures rated to NEMA 4/12. The lens handles service up to 500°F (260°C), and the 2 mm thickness adds strength in a slim profile. Therefore, the Teledyne Flir IR Inspection Window (IRW-3C) gives you a simple, robust path to faster, safer inspections. It keeps your process steady, and it keeps your team confident.

Key features
  • Closed-panel inspections for energised gear
  • Helps reduce arc flash risk on site
  • Supports NFPA 70E safe work methods
  • Works with short, mid and longwave IR
  • Allows visible light for targeting aid
  • PIRma-Lock locknut secures the assembly
  • No extra screws needed during install
  • Anodised aluminium frame resists corrosion
  • Stainless option avoids mixed metal issues
  • Simple fit for routine condition checks
  • Smooth action promotes fast survey flow
  • Suits indoor and outdoor enclosure use
