The interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V.
Motor protection specifics and built-in releases
This MCCB is engineered for motor protection, meaning the trip curve is shaped to handle motor inrush without nuisance tripping, yet still clear a locked-rotor or phase-loss fault. Phase failure detection is included — that's a key feature for a motor circuit: if one phase drops out, the breaker opens before the motor single-phases and cooks the winding. The UVR means the breaker drops out if control voltage is lost — common in safety circuits or remote emergency-stop chains. The auxiliary and alarm contacts let a PLC or SCADA system know the breaker state without adding external relays. A trip indicator is present, so a quick glance at the panel tells you whether the breaker tripped on fault or was manually opened. The basic switch module is order code 3VA2216-5MN32-0AA0 — useful if you ever need to swap just the switch body and keep the existing release and aux block.
That 86 mm depth is the panel depth behind the mounting surface — check your enclosure depth if you're retrofitting into a shallow gland-plate area.
