— IEC/EN 60947-4-1.
Rated ultimate short circuit breaking capacity I
cu
— IEC/EN 60947-2.
Rated operational short circuit breaking capacity I
cs
— IEC/EN 60947-2.
Table 206. Manual Motor Protector Short Circuit Ratings
No upstream protective device required, as it is the auto-protected range (100/150 kA — Frame B, 150 kA — Frame D).
N = Not required.
XTPR…BC1, XTPT, XTPM — Required back-up fuse if the short circuit current exceeds the rated conditional short circuit current (I
cc
> I
q
);
XTPB, XTPR...DC1 — Fuse (A gG/gL) for enhancing the switching capacity of the motor protective circuit breaker to 100 kA.
