The Siemens 3VA2116-5KP46-0AA0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 4-pole construction and ETU850 electronic trip unit make it a line-protection device with communication capability, suited for main or feeder breakers in distribution panels where selectivity and remote monitoring matter.
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. For a 480 V panel with a 100 kA available fault current, this breaker holds 75.6 kA at 500 V, which covers the 480 V case with headroom. The 690 V figure (3.7 kA) is a reminder that at higher voltages the arc extinction challenge grows; this is not a 690 V main breaker for high-fault installations.
Dimensions are 181 mm high, 140 mm wide, and 86 mm deep — a 4-pole MCCB footprint that fits standard Siemens 3VA2 mounting accessories.
