The Siemens 3VA2116-5HL36-0KC0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 3-pole design and line-protection characteristic make it a straight choice for feeder or main breaker duty in a distribution panel where you need a single interrupting device that holds its rating in a warm enclosure.
Breaking capacity across the voltage range
This MCCB delivers 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. Those figures tell you the available fault current the breaker can safely interrupt at each voltage level — critical for coordination studies and verifying SCCR compliance of the downstream panel. At typical 400 V class distribution voltages the 121 kA rating covers most industrial service entrances without needing a current-limiting fuse upstream.
Integrated accessories
Factory-fitted with a shunt trip (STL) for remote tripping and two auxiliary switches (HQ) for status feedback to a PLC or indication lamp. No undervoltage release, no ground-fault module, no communication function — this is a clean line-protection breaker with the most common add-ons already built in. The shunt trip lets a safety circuit or emergency-stop button open the breaker remotely without needing a separate contactor.
