The Siemens 3VA2110-5HN36-0HA0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C through 70 °C ambient, meaning no derating across the typical panel temperature range. It is a 3-pole device designed for line protection, with an integrated shunt trip (STL) auxiliary release for remote tripping.
Breaking capacity and fault clearance
This MCCB delivers 187 kA breaking capacity at 240 VAC, 121 kA at 415 VAC and 440 VAC, 75.6 kA at 500 VAC, and 3.7 kA at 690 VAC. The steep drop at 690 V means this breaker is sized for 480 V and below systems — at 690 V the interrupting rating falls to 3.7 kA, which is below most industrial fault-current levels at that voltage. For 690 V applications, a higher-rated 3VA2 variant would be needed.
Physical fit and panel integration
Dimensions are 181 mm height, 105 mm width, 86 mm depth. The 105 mm width is the standard 3-pole MCCB footprint for the 3VA2 frame — it occupies the same panel cutout as other 3VA2 3-pole units. The 86 mm depth includes the shunt trip projection; verify clearance to the enclosure door or deadfront.
Key ratings and design
Rated insulation voltage is 800 V. Maximum power loss is 10 W. The shunt trip (STL) allows remote tripping. The base switch is 3VA21105HN360AA0.
