The Siemens SENTRON 3VA2010-5HL36-0KH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C, meaning no derating is needed in a warm enclosure — a practical advantage for densely packed panels where heat buildup is a concern. Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V, so it handles high-fault scenarios typical in industrial distribution without cascading upstream. Designed for line protection, it ships with a shunt trip (STL) and two auxiliary switches plus one trip alarm switch (HQ), giving the controls engineer the signals needed for remote trip indication and interlocking without adding separate modules.
Panel integration
The 3VA2010-5HL36-0KH0 mounts on a DIN rail or directly to a backplate via the standard 4-screw pattern. At 105 mm wide and 86 mm deep, it fits a standard 600 mm enclosure without crowding the gland plate. The shunt trip (STL) and auxiliary switches are factory-installed, so no field wiring of add-on modules is required — just terminate the line and load conductors, connect the control voltage for the shunt trip, and wire the auxiliary contacts to the PLC or annunciator.
