SENTRON 3VA2163-6HN32-0KH0 — 63 A MCCB, line protection, current production
The Siemens SENTRON 3VA2163-6HN32-0KH0 is a 3-pole molded case circuit breaker rated 63 A continuous, designed for line protection in distribution panels. Breaking capacity runs 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 240 V figure is the headline for high-fault commercial services. The breaker carries a shunt trip release (STL) and a 2-auxiliary-switch plus 1-trip-alarm-switch HQ configuration, so it integrates into a monitored feeder or a remote-trip scheme without an add-on module.
Breaking capacity by voltage — where the 242 kA matters
At 240 V the breaker interrupts 242 kA — that is the high-fault rating for a 63 A frame. At 415/440 V it drops to 187 kA, at 500 V to 121 kA, and at 690 V to 3.7 kA. The 690 V figure is low enough that you would check coordination with upstream devices before using this breaker on a 690 V feeder. For a standard 480Y/277 V panel the 187 kA at 440 V is the relevant number, and it gives substantial SCCR headroom over a typical 65 kA or 100 kA rated bus.
Dimensions and panel fit
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 105 mm width is the standard 3-pole MCCB footprint for this SENTRON frame — it occupies three 35 mm DIN-rail positions or the corresponding panel-mount cutout. The 86 mm depth leaves clearance for rear-connected busbars or a standard deadfront enclosure.
