Siemens 3VA2063-5HN32-0AC0 — 63 A SENTRON MCCB, 187 kA SCCR
The Siemens 3VA2063-5HN32-0AC0 is a SENTRON 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C through 70 °C with no derating across that band — the full 63 A holds all the way to 70 °C ambient. Its interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415/440 V, and 75.6 kA at 500 V; at 690 V it still clears 3 kA. That 187 kA figure at 240 V means it can be placed upstream of a high-fault panel without needing a current-limiting fuse ahead of it — the breaker itself handles the full available fault current at that voltage level. Rated insulation voltage is 800 V, and the unit is designed for line protection — not motor protection or ground-fault monitoring. It ships with the basic switch 3VA20635HN320AA0 and carries two HQ auxiliary switches. No undervoltage release, no voltage trip, no communication function. This is a straightforward, high-interrupting MCCB for distribution panels where selectivity and fault-clearing headroom are the priorities.
Panel Fit & Mounting
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. The 105 mm width is the standard 4-module footprint for SENTRON 3VA breakers — it drops into the same DIN-rail or panel-mount cutout as other 3VA 3-pole units. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Maximum power loss is 5.4 W.
Compliance & Approvals
As a SENTRON MCCB, the 3VA2063-5HN32-0AC0 carries the standard Siemens compliance documentation for the series — RoHS, REACH, UL, and IEC certifications are part of the product's regulatory package. Specific certificate numbers and declaration files are available with the datasheet set.
