Inlet Voltage and Current
•
All models 120/208 Vac, 50/60 Hz, three-phase wye
•
All models 24 A continuous load / 30 A maximum
Overload Protection (standard)
•
All models include a four-pole main circuit breaker
wired with all three phases and neutral passing
through the breaker.
•
All branch breakers are UL 489, 16 A continuous load
(20 A maximum)
•
Based on NEC regulations, traditional load ratings
are de-rated to 80% for continuous duty. For example,
a traditional 30 A maximum rating is now interpreted
and labeled as a 24 A continuous duty rating. Optima
current ratings are shown with continuous/maximum
rating values.
Surge Suppression (standard)
•
All models include a thermally protected varistor on
each phase with a single-pulse energy rating of 120
joules.
•
All models have a peak surge current rating of
10,000 A for a single pulse 8x20µs wave.
Environment
•
Operating Temperature: 32°F to 122°F
•
Maximum Altitude: 6,562 feet
•
Relative Humidity: 5% to 85% non-condensing
EMI Filter (standard)
•
All models have < 1.0 mA leakage.
