The Siemens SENTRON 3VA2216-5KQ32-0BB0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across its full ambient temperature range of -25 °C to 70 °C — no derating needed from 40 °C through 70 °C, which simplifies panel sizing in warm environments. Breaking capacity hits 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V. That 187 kA figure at 240 V tells you this breaker is built for high-fault industrial panels where the available fault current is serious — not a light-duty distribution board. Designed for line protection per the product designation, with an undervoltage release (UVR) fitted and two HP auxiliary switches for status feedback to a PLC or remote I/O. Communication function is onboard, so it can talk to a higher-level system for monitoring or load-shedding coordination.
Dimensions and panel fit
Footprint is 105 mm wide by 181 mm tall by 86 mm deep. That 105 mm width is a standard 3-pole MCCB form factor for this SENTRON frame size — check your existing panel's busbar spacing and door cutout before committing the BOM line.
What the ratings mean for your BOM
The 160 A full-scale rating with the adjustable thermal-magnetic trip unit (initial value 32 A, full-scale 160 A) lets you set the continuous pickup to match the downstream load — conveyor motor, pump, or feeder circuit. The 22.2 W maximum power loss at full load is heat that has to be dissipated inside the enclosure; factor it into your panel thermal budget. Storage temperature range of -40 °C to 80 °C covers cold warehouses and hot shipping containers. Operating range -25 °C to 70 °C means it's fine for unheated plant floors in temperate climates, but not for freezer applications below -25 °C.
