According to the short-circuit resistance diagram of UL508
RiLine's short-circuit resistance has been tested in all aspects. Short circuit resistance
The degree shall be evaluated according to the effective value of short circuit current (IRMS) which lasts for at least 3 cycles (60ms) according to UL standard.
During the test, the detection equipment is set to their respective effective values (IRMS).
The short-circuit impulse current Ip generated here is shown by the following short-circuit resistance diagram.
Bus support
For feeder circuit 700A, 3-pole
60mm bus center distance for bus 15x5 – 30x10mm
explain:
SV9340.050 and E-Cu30x5/10mm
The standby fuse can achieve the following short circuit values:
– Bracket spacing: 350mm
– Fuse: ClassL800A
–IRMS:50kA
Set value IRMS (Ieff.) of detection equipment, without standby fuse:
Bus support
For feed circuit
700A (PLS800)/1400A (PLS1600), 3-pole
60mm bus center distance for PLS special bus
explain:
SV9342.050(PLS1600)
The standby fuse can realize the following short circuit values:
– Bracket spacing: 250mm
– Fuse: ClassL1400A
–IRMS:65kA
