The Siemens SENTRON 3VA1096-3ED32-0HC0 is a 3-pole molded case circuit breaker (MCCB) rated 16 A at 40 °C, designed for line protection in distribution panels. Breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that govern its fault-interrupting capability at the point of common coupling. Rated insulation voltage is 800 V, and maximum power loss is 10.6 W.
Breaking capacity and thermal derating
Breaking capacity drops with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. This is the SCCR the breaker can clear without welding or venting — match it to the available fault current at the installation point. Thermal rating holds at 16 A from 40 °C through 55 °C, then derates to 15 A at 60 °C through 70 °C. Operating ambient range is -25 °C to 70 °C; storage from -40 °C to 80 °C.
Auxiliaries and integration
This MCCB ships with 2 auxiliary switches (HQ type) and a shunt trip (STL) for remote tripping. No undervoltage release, no ground-fault monitoring, no communication module — it is a standalone line-protection device. Panel cutout dimensions: 130 mm height, 76.2 mm width, 70 mm depth. The supplied basic switch order code is 3VA10963ED320AA0.
