Siemens 3VA1032-4ED36-0AE0 — SENTRON MCCB, 32 A, Line Protection
Breaking capacity is the headline number for an MCCB: this unit delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
The 32 A rating holds from 40 °C through 50 °C, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C. Maximum power loss is 10.6 W per pole, so three poles dissipate roughly 32 W total; that heat must be vented or the enclosure must be sized to keep internal ambient below the derating curve.
Auxiliary Switching and Variant Note
This variant ships with provision for up to 4 auxiliary switches (HQ type) — the basic switch supplied is order code 3VA10324ED360AA0. That means the breaker comes with the internal mechanism for auxiliary contacts, but the actual switch modules are ordered separately and snap into the designated slots.
