What this 160 A MCCB delivers
The Siemens 3VA2216-5MN32-0KC0 is a 3-pole SENTRON molded case circuit breaker rated 160 A continuous across the full -25 °C to 70 °C operating range — no derating needed until you push past 70 °C ambient. That 160 A holds steady from 40 °C straight through 70 °C, which simplifies panel thermal budgeting when the enclosure runs hot. 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 4.5 kA at 690 V. That 187 kA at 240 V is the number to check for high-fault utility feeds or transformer secondaries; the 121 kA at 415 V still covers most European industrial distribution boards without upstream fusing. This is a motor-protection-design MCCB — it includes phase failure detection and the adjustable thermal-magnetic trip curve is set for motor starting inrush, not resistive loads. The basic switch variant is 3VA2216-5MN32-0AA0, and the order code adds a shunt trip (STL) plus two HQ auxiliary switches.
Panel fit and wiring
Footprint: 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is the standard 3-pole MCCB slot on a DIN rail or panel-mount plate — it matches the 3VA1 and 3VA2 family grid, so a panel laid out for a 3VA1110 will accept this breaker without drilling new mounting holes or re-cutting the gland plate. Maximum power dissipation is 19.7 W at rated load — account for that in enclosure thermal calculations, especially if the panel is densely packed or NEMA-rated. The shunt trip (STL) and two HQ aux switches are pre-installed; verify the aux contact wiring matches your PLC input voltage before landing the control wires.
