63 A MCCB with full interrupting range
The Siemens SENTRON 3VA2163-7HN32-0DL0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity reaches 330 kA at 240 V, dropping to 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V. That 330 kA figure at 240 V covers high-fault scenarios common in industrial distribution — large transformers or parallel-fed busways — where a standard MCCB would cascade failure upstream.
Line protection with undervoltage release
The auxiliary switch block carries two auxiliary switches plus one trip alarm and one electrical alarm switch (HQ type), giving status feedback for PLC or SCADA inputs. No communication function or ground-fault monitoring is integrated; those are separate order-code branches.
