What this MCCB carries and where it lands
The Siemens 3VA2116-7KP32-0AA0 is a SENTRON molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That makes it a fast mover for line-protection duty in distribution panels where the load profile stays under 160 A and the ambient is warm. Breaking capacity hits 330 kA at 240 V AC, 242 kA at 415 V, and still holds 187 kA at 500 V — serious SCCR headroom for high-fault installations. At 690 V it drops to 3.7 kA, so keep that in mind if the line side runs above 500 V. Three-pole construction, front protection IP40, and the ETU850 electronic trip unit with communication function onboard. No undervoltage release or ground-fault monitoring on this variant — if those are needed, you are looking at a different order code in the 3VA2 family.
Panel fit and footprint
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard MCCB footprint for the 160 A frame class. Mounts on a DIN rail or directly to the backplate; the 86 mm depth leaves room for rear-connected busbars without crowding the gland plate. Maximum power loss is 25.5 W at rated load, which factors into enclosure ventilation calcs if the panel is sealed. Storage range from -40 °C to 80 °C; operating range -25 °C to 70 °C.
