The Siemens SENTRON 3VA1116-4EF36-0HA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. It's designed for line protection in distribution panels, switchgear, and motor control centers where a high interrupting rating is needed — 121 kA at 240 V AC, 75.6 kA at 415 V, and still 11.9 kA at 690 V.
Breaking capacity and thermal performance
The 160 A rating holds flat from 40 °C to 50 °C, then derates to 150 A at 70 °C — useful if the breaker sits in a warm enclosure near transformers or drives.
Form factor and panel fit
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact 3-pole MCCB footprint that mounts on a DIN rail or panel plate. The shunt trip (STL) auxiliary release is factory-installed, so no field retrofit is needed for remote trip capability.
