The breaker includes phase failure detection as standard, which trips the circuit if one phase drops out, protecting three-phase motors from single-phasing damage.
This MCCB delivers 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V.
Power loss and auxiliary wiring
Maximum power dissipation is 37.5 W at rated load — factor that into the enclosure thermal budget, especially in a multi-breaker lineup. The auxiliary switch block includes two form-C auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ), giving plenty of feedback points for remote monitoring. The basic switch core is order code 3VA2325-5MN32-0AA0, which is the internal switching mechanism; the -0HL0 suffix adds the shunt trip and the specific auxiliary configuration.
