Hotspots in electrical cabinets can be quickly pinpointed while circuits are energized and under load, using Mikron’s SpyGlass™ Lens and economical ViewPorts.
The unique design of the Viewport uses only a 0.62˝ aperture, maintaining the integrity and safety rating of the cabinet, without the need for a metal screen barrier which can skew thermal readings, or break and compromise safety. The Viewport is unaffected by moisture, dirt, UV and corrosive environments – it never needs cleaning or replacement glass. When used with the plastic-tipped SpyGlass™ lens, there is no “path to ground” through the camera, enhancing operator safety.
These patented viewports have received a UL approval number of NITW2.E228318 for use in the United States and a UL approval number of NITW8.E228318 for use in Canada. These UL approved viewports are designed for use with NEMA Type 1, 2, 3, 3R, 4, 5, 12, 12K, and 13 enclosures. They are available in three styles, with a list price starting under $50.
When used in conjunction with Mikron’s SpyGlass Lens this patented and UL approved method raises the safety and convenience standard for thermal inspections by encouraging frequent examinations of electrical switchgear without having to open cabinet doors or de-energize circuits.
