The Siemens 3VA2010-5HN32-0HA0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Three poles, with a shunt trip (STL) auxiliary release built in.
Dimensions and panel fit
The 3VA2010-5HN32-0HA0 measures 181 mm high by 105 mm wide by 86 mm deep. That 105 mm width is a standard 3-pole MCCB footprint for this class — it fits existing SENTRON 3VA2 panel cutouts and busbar arrangements without re-drilling. The 86 mm depth leaves clearance for rear-mounted accessories and cable bend radius in a typical distribution board.
Key ratings in context
Rated insulation voltage is 800 V. Power loss maxes at 13.5 W — relevant for thermal budgeting inside a sealed enclosure. The shunt trip release (STL) allows remote tripping via a control signal, common in emergency-stop or undervoltage protection schemes.
