Fluke CV300, Inspection Window for use with NEMA 12 Enclosure, NEMA 4 Enclosure

The Fluke CV300 is an infrared inspection window designed to provide safe, repeatable access to electrical components housed inside NEMA 12 and NEMA 4 enclosures. It allows technicians to perform thermal inspections without opening panel doors, helping maintain arc-flash boundaries and reducing exposure to energised equipment. The window is developed to withstand routine industrial conditions while preserving enclosure integrity.

Key Construction and Performance Attributes

• Upholds environmental protection.
• Durable frame and secure locking mechanism ensure long-term stability.
• Wide viewing area supports thermal imaging on breakers, bus bars, connections and switchgear components.
• Helps reduce risk by eliminating the need to open energised cabinets during routine checks.

Maintenance and Safety Programs

The CV300 supports safer maintenance practices by allowing infrared surveys to be performed with doors closed and covers intact. This helps technicians stay within defined safety boundaries and reduces the need for extensive PPE during quick visual or thermal checks. Its installation provides a consistent inspection point, improving the repeatability of condition-monitoring programs across equipment cycles.
