Bussmann Rating
LPJ-21/2SP 2.5 A, 600 V
Table 10.12 D1h–D8h Space Heater Fuse Recommendation
If the drive is not supplied with a mains disconnect, contactor, or circuit breaker, the short circuit current rating (SCCR) of
the drives is 100000 A at all voltages (380–690 V).
If the drive is supplied with a mains disconnect, the SCCR of the drive is 100000 amps at all voltages (380–690 V).
If the drive is supplied with a circuit breaker, the SCCR depends on the voltage. See Table 10.13.
