Specifications
Inverter overload capability:
At 0–30°C:
● 100% < load ≤ 105%: works for a long time
● 105% < load ≤ 110%: transfers to bypass mode after
60 min
● 110% < load ≤ 125%: transfers to bypass mode after
10 min (tolerance ± 0.1 min)
● 125% < load ≤ 150%: transfers to bypass mode after
1 min
● Load > 150% or a short circuit occurs: runs for 200
ms
At 30–40°C:
● 100% < load ≤ 105%: works for a long time
● 105% < load ≤ 110%: transfers to bypass mode after
60 min
● 110% < load ≤ 125%: transfers to bypass mode after
3 min (tolerance ±0.1 min)
● 125% < load ≤ 150%: transfers to bypass mode after
30s
● Load > 150% or a short circuit occurs: runs for 200
ms
Bypass overload capability:
● 30°C environment: works for a long term at 135%
load.
● 40°C environment: works for a long term at 125%
load.
● If the bypass single-phase or three-phase has 150%–
200% load, the bypass can keep working for 5 min.
● If the bypass single-phase or three-phase has more
than 200% load, the bypass can keep working for 1
minute.
● If the load exceeds 1000%, the bypass can keep
working for 100 ms.
● 40 A circuit breaker: 0.75
● 63 A circuit breaker: 0.7
