True RMS three phase voltage sensing on Source 1, Source 2 and Load
Frequency sensing on Source 1 and Source 2
Mechanical (cable) and electrical interlocking to prevent paralleling of sources
Safe manual operation under full load with permanently affixed operating handle
Ambient temperature range: -40°C to 40°C (-40°F to 104°F)
Operating temperature range: -20°C to 70°C (-4°F to 158°F)
Operating humidity: up to 90%
Relative humidity (non-condensing)
Source paralleling duration is limited to 100 msec or less
Source availability indication
Controls And Wiring
All controls relays and industrial grade relays are totally encapsulated to minimize exposure to dust and dirt. Lugs are 90º rated and all control wire is #16 AWG, type XLPE with a 125º temperature rating.
Enclosure
Durable powder-coated steel NEMA 1, 3R or 12 enclosures with three door hinges to ensure proper support of the door and door mounted devices. The hinges have removable hinge pins to facilitate door removal for easy wall mounting or service and are supplied with pad-lockable latches.
