What this 3VA2216-7MN32-0DC0 is and what it does
This is a Siemens SENTRON 3VA2216-7MN32-0DC0 molded case circuit breaker (MCCB) designed specifically for motor protection. It carries a continuous current rating of 160 A at 40 °C — flat across the full ambient range up to 70 °C, so no derating headache in a hot panel (–). Three poles, phase failure detection built in, and it ships with an undervoltage release (UVR) plus two HQ auxiliary switches. The supplied basic switch variant is 3VA2216-7MN32-0AA0. If your BOM calls for motor branch circuit protection with UVR and aux contacts pre-installed, this saves you a separate order and wiring step.
Interrupting capacity — what the numbers mean for your panel
The 3VA2216-7MN32-0DC0 delivers 330 kA interrupting capacity at 240 V AC, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. That 330 kA at 240 V is high — typical for large transformer-fed services or industrial distribution where fault current is substantial. At 690 V the 4.5 kA figure is lower, so verify your system voltage and available fault current before committing this breaker to a 690 V feeder. For most 400 V class motor circuits, the 242 kA rating gives plenty of headroom.
Panel fit — dimensions and mounting
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep (–, –). That 105 mm width is a standard 3-pole MCCB footprint for this class — it'll drop into a panel cutout or mounting base sized for a SENTRON 3VA fixed breaker. Depth of 86 mm (3.39 in) leaves room for rear bus connections or cable routing behind the panel door.
