The Siemens SENTRON 3VA2010-6HN36-0BC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current (Iu) without derating up to 50 °C — above that, it steps down to 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C, so plan your thermal budget if the breaker sits in a hot enclosure. Breaking capacity hits 242 kA at 240 V AC and 187 kA at 415/440 V, then drops to 121 kA at 500 V and 4 kA at 690 V — the 240 V figure is the headline, but the 415 V rating is the one that governs most industrial distribution panels in Europe and Asia.
Panel fit: dimensions and integration
The 86 mm depth leaves room for rear-connected busbars or cable lugs in a shallow enclosure.
Undervoltage release and auxiliary contacts
The 2 HQ auxiliary switches provide independent NO/NC contacts for remote status indication; they're wired separately from the main power path, so the PLC sees the breaker state even if the UVR has already opened it. No voltage trigger or trip indicator on the front face, so you'll rely on the aux contacts or the ETU's local LED for trip indication.
