SENTRON 3VA1150-5EF32-0HH0 — 50 A MCCB with TM240 Release
Interrupting Capacity and Selectivity Planning
At 240 V the 3VA1150-5EF32-0HH0 clears 187 kA — enough for most transformer-secondaries and large motor-control-center feeds.
Current Derating and Ambient Temperature
Above that, current tapers: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. In a tightly packed panel with multiple breakers, the 70 °C ceiling (maximum operating temperature) means the 50 A frame can still serve a 45 A continuous load at the top of the ambient range. The front face is IP40-rated — adequate for general-purpose indoor enclosures but not washdown zones.
Auxiliary Contacts and Shunt Trip Configuration
This variant ships with two auxiliary switches plus one separate trip-alarm switch (HQ configuration). The integrated shunt trip (STL) release is designed for remote tripping; its order code is 3VA9688-0BL30.
