The SENTRON 3VA2010-5HN36-0HA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, with a shunt trip release (STL) for remote tripping. It's designed for line protection in distribution panels, sized at 86 mm deep by 105 mm wide by 181 mm tall — a standard footprint that fits most 3-pole MCCB mounting slots without re-drilling the backplate.
Interrupting capacity and selectivity
Rated interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. That 187 kA at 240 V means this breaker can clear a bolted fault on a 240 V secondary bus without upstream fuses needing to open — useful for high-fault panels near large transformers. The 100 A frame holds its rating flat from 40 °C through 70 °C ambient, so no derating curve to calculate in a warm enclosure.
Shunt trip and auxiliary release
The shunt trip (STL) release allows a remote signal — from an E-stop, fire alarm relay, or PLC digital output — to trip the breaker without an operator at the panel. No undervoltage release on this variant, so it won't drop out on a brownout; the shunt trip is a separate voltage-trigger input that needs a sustained signal to hold the trip coil energized.
