The Siemens SENTRON 3VA2010-5HN36-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to the top of the enclosure's thermal curve. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, which gives selectivity headroom for most distribution panels without cascading upstream.
Built-in undervoltage release and auxiliary switching
The two auxiliary switches provide position feedback (open/closed) to a PLC or status lamp without an external limit-switch block.
Line protection design, no communication or ground-fault
The 3VA2010-5HN36-0DC0 is configured for line protection — it is not a ground-fault or communication-enabled breaker.
Maximum power loss is 16 W, which is manageable for enclosed panels but should be factored into thermal calculations if the breaker is in a sealed cabinet with other high-current devices.
