160 A MCCB with 2 auxiliary switches and shunt trip
The Siemens SENTRON 3VA2116-5HL32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in distribution panels. Its interrupting capacity hits 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 — that 187 kA figure at 240 V covers high-fault utility feeds and transformer secondaries where fault currents can spike. The breaker ships with a shunt trip (STL) for remote opening and 2 HQ auxiliary switches for status feedback to a PLC or annunciator. The 160 A rating holds flat across the full operating temperature range from 40 °C through 70 °C — no derating needed in a warm panel. That simplifies panel thermal budgeting: you can load it to 160 A even in a 70 °C enclosure without recalculating.
Mounting and integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — fits standard MCCB panel cutouts and bus-bar spacing. The 86 mm depth means it clears most gland plates and back-panel wiring troughs without interference. Max power loss is 25.5 W, which helps when sizing enclosure ventilation or forced cooling for a multi-breaker lineup.
