Short-circuit stability and protection
(1) Maximum instantaneous start-up current (maximum operating current of the compressor + fan current + locked rotor current of the compressor).
(2) Power input, compressor and fan, at the unit operating limits (saturated suction temperature 10 °C, saturated condensing temperature 65 °C) and nominal voltage of
400V (data given on the unit nameplate).
(3) Standardised Eurovent conditions: evaporator entering/leaving water temperature 40 °C/45 °C, outside air temperature db/wb = 7 °C/6 °C.
(4) Maximum unit operating current at maximum unit power input and 400 V (values given on the unit nameplate).
*
Maximum unit operating current at maximum unit power input and 360 V.

Value without upstream protection
Short-term current at 1 s - Icw - kA rms
Admissible peak current - Ipk - kA pk
Maximum value with upstream protection by circuit

Conditional short-circuit current Icc - kA rms
Circuit breaker - Compact range
Reference number
(2)
Value with upstream protection (fuses)
Conditional short-circuit current Icc - kA rms
Fuse (gL/gG)
(1) Earthing system type
(2) If another current limitation protection system is used, its time-current and thermal constraints (l²t) trip characteristics must be at least equivalent to those of the
recommended circuit breaker.
The short circuit stability current values above are suitable with TN system.
