SENTRON 3VA2 MCCB — 160 A Continuous, 1 600 A Frame
The Siemens SENTRON 3VA2116-5HN36-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 160 A continuous current across the full ambient range from 40 °C to 70 °C with no derating needed. The frame is sized at 1 600 A maximum, giving headroom for high-fault installations. Breaking capacity is 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 — these numbers govern selectivity coordination with downstream breakers in a distribution panel. Power loss is 25.5 W maximum, which factors into panel thermal budgeting when the breaker is enclosed.
Auxiliaries and Releases
This variant ships with a shunt trip (STL) for remote tripping, plus a complement of auxiliary switches: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ design). The basic switch supplied is order code 3VA21165HN360AA0. No undervoltage release, ground-fault monitoring, or communication function is fitted on this order code — those are separate option variants within the 3VA2 family. A voltage trigger and trip indicator are present, aiding fault diagnostics on the panel front.
Physical Fit and Environment
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for DIN-rail or panel-mount installation in a distribution board. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The continuous current rating holds flat across the full operating range, no derating curve to apply.
