Siemens SENTRON 3VA2110-5HN36-0JC0 is a 3-pole molded case circuit breaker rated 100 A continuous across the full ambient range from 40 °C to 70 °C — no derate curve to chase. Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. Designed for line protection, it ships with a factory-fitted shunt trip (STL) and two HQ auxiliary switches. Current production part, sourced to order against an RFQ.
What the ratings mean for fit
The 100 A rating holds flat from 40 °C to 70 °C — no thermal derating needed in a hot panel. That matters when the breaker sits near other heat sources or in a non-ventilated enclosure. 187 kA at 240 V is the highest interrupting rating on this frame — sized for high-fault service-entrance or large sub-distribution boards. At 690 V the rating drops to 3.7 kA, so verify the available fault current if this is going into a 690 V system. Shunt trip (STL) is fitted ex-works — remote trip via a control signal is ready to wire. Two HQ auxiliary switches give status feedback for the PLC or indicator lamps.
Panel footprint
Mounts in a standard panel cutout. Dimensions: 181 mm high, 105 mm wide, 86 mm deep. The 3-pole frame with shunt trip and aux switches fits within the standard 3VA2 envelope — no extra width for the accessories.
