The Siemens 3VA2063-5HL36-0AH0 is a SENTRON 3VA2 molded case circuit breaker rated for 63 A continuous current across the full ambient range from -25 °C to 70 °C — no derating needed up to that ceiling.
Interrupting capacity by voltage level
This MCCB delivers 187 kA interrupting capacity at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. At 690 V it still clears, but only for low-fault installations.
Auxiliary switching and trip indication
The trip indicator gives a local mechanical flag — no separate voltage trigger or undervoltage release is included, so if you need remote shunt trip or UVR, that has to be added externally. No communication function onboard; this is a standalone breaker, not a metering or power-monitoring device.
No special cutout required beyond the standard 3VA2 footprint. The 5.4 W maximum power loss is modest; ventilation around the breaker is still advisable if it's grouped with other high-current devices in a sealed enclosure.
