Siemens 3VA2163-5HL32-0CH0 — SENTRON MCCB for Line Protection
Interrupting capacity reaches 187 kA at 240 V AC and 121 kA at 415/440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V. The steep drop at 690 V (3.7 kA) means this frame is not intended for 690 V high-fault installations — if your system runs 690 V with available fault current above a few kA, step up to a higher-rated SENTRON frame.
Auxiliary Switching and Undervoltage Release
The basic switch assembly carries order code 3VA21635HL320AA0. Power loss is rated at 6.5 W maximum — a modest thermal load for a 63 A frame, but worth noting if the breaker is grouped tightly in a non-ventilated enclosure.
