SENTRON 3VA2116-5HL32-0HH0 — 160 A MCCB with ETU320
The Siemens 3VA2116-5HL32-0HH0 is a SENTRON molded case circuit breaker rated for 160 A continuous current across a 3-pole line-protection configuration. It carries an ETU320 electronic trip unit and a shunt trip (STL) auxiliary release, plus 2 auxiliary switches and 1 trip alarm switch (HQ). The rated insulation voltage is 800 V, and the interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 4.25 kA at 690 V — numbers that govern the available fault current the breaker can safely clear at the installed voltage level.
Breaking capacity and thermal derating
The 160 A rating holds flat from 40 °C through 50 °C, then steps down to 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. For a panel that runs warm — say, adjacent to drives or transformers — the 55 °C derating to 154 A is the figure to size against, not the 160 A nameplate. The maximum power loss is 25.5 W, which factors into enclosure ventilation planning.
Integration and mounting
The 3VA2116-5HL32-0HH0 measures 105 mm wide, 181 mm high, and 86 mm deep — a 3-pole frame that fits standard SENTRON panel cutouts and busbar systems. The operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. The ETU320 release is field-configurable for line protection; the shunt trip (STL) allows remote tripping, and the auxiliary contact block (2 aux + 1 alarm) provides status feedback to a PLC or annunciator.
