Three poles, rated 63 A continuous at up to 70 °C ambient without derating (– confirm the full 63 A holds across the 40–70 °C range), so no temperature correction factor needed in a warm enclosure. The adjustable thermal-magnetic trip unit covers 189 A minimum to 945 A maximum — that's a 5:1 adjustment band, giving flexibility to match the motor full-load current without swapping the breaker. Breaking capacity is the headline number for a panel builder doing fault coordination: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Auxiliary and control wiring
The trip alarm switch changes state only when the breaker trips on fault (not on manual off), which is useful for remote fault annunciation. No undervoltage release fitted, so if you need UVR for a safety circuit, that's a field-add option. No communication module or phase-failure detection onboard — this is a straight electromechanical MCCB, not a smart breaker. If you need power monitoring or remote reset, you'd add the 3VA communication module externally. The basic switch variant is 3VA2163-7MS36-0AA0 — the -0HH0 suffix adds the shunt trip and auxiliary switches.
