What the ratings mean for your panel
The Siemens SENTRON 3VA2010-6HL32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full operating temperature range from -25 °C to 70 °C — no derating needed up to 70 °C ambient. That 100 A holds at every 5 °C step from 40 °C through 70 °C, so it's a straight drop-in for a 100 A bus without recalculating thermal headroom. Breaking capacity is where this breaker earns its place in high-fault panels: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. At 240 V it handles the highest available fault current from a typical 1500 kVA transformer secondary — you can coordinate it upstream without worrying about series ratings. Rated insulation voltage is 800 V, so it's suitable for 480/277 V and 600 V systems with margin. The 3-pole design covers three-phase line protection per the product designation.
Sourcing and lifecycle
For BOM freeze or PCN watch, the SENTRON 3VA series is Siemens' current-generation MCCB platform — replacements and upgrades within the family are documented through normal product change notices. We source this exact order code to order; submit an RFQ for current pricing and availability.
Panel fit and dimensions
Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — a standard MCCB footprint that fits most 3-pole breaker slots in switchboards and panelboards. The 105 mm width matches the typical 4.13-inch pole spacing for three-phase distribution. Maximum power loss is 13.5 W, which keeps heat rise manageable in enclosed panels. No undervoltage release, no trip indicator, and no communication function on this variant — it's a straight line-protection breaker with 4 HQ auxiliary switches.
