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
This MCCB ships with an integrated undervoltage release (UVR) and two auxiliary switches (HQ design). The UVR trips the breaker when control voltage drops below the dropout threshold — standard for safety interlocks, emergency-stop circuits, or generator-transfer schemes where loss of control power must open the main feeder. 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. There is no integrated ground-fault monitoring and no communication function, so it is a straightforward thermal-magnetic or electronic-trip MCCB for feeder or branch-circuit protection where remote monitoring is handled externally.
Panel fit and environmental limits
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a standard SENTRON 3VA frame that fits existing DIN-rail or panel-mount cutouts for the series. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. 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.
