The Siemens SENTRON 3VA2116-6HL32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated at 160 A continuous current, designed for line protection in distribution panels. It carries a shunt trip release (STL) for remote tripping — useful in emergency-stop or load-shedding circuits where you need to kill power from a PLC or safety relay without pulling the handle.
Breaking capacity and selectivity
Breaking capacity is the headline number that decides whether this breaker clears a fault without exploding. At 240 V it interrupts 242 kA — enough for a high-capacity transformer secondary. At 415 V and 440 V it holds 187 kA, dropping to 121 kA at 500 V. At 690 V it's still rated 3.7 kA, which covers most motor-circuit faults on a 690 V bus. The 800 V rated insulation voltage (Ui) means the internal clearance is specced for 690 V systems with margin.
Thermal performance and derating
The 160 A continuous rating holds flat from 40 °C up to 70 °C ambient — no derating curve to calculate in a hot panel. Maximum power loss is 25.5 W, which is manageable for a 160 A frame but worth checking against the enclosure's thermal budget if you're packing multiple breakers in a sealed box. Operating range is -25 °C to 70 °C; storage from -40 °C to 80 °C.
Integration and dimensions
Mounts on a standard DIN rail or panel-mount plate. Dimensions: 105 mm wide (4.13 in), 181 mm tall (7.13 in), 86 mm deep (3.39 in). Three-pole footprint matches other SENTRON 3VA frames, so a panel laid out for a 3VA2 will accept this unit without re-drilling. The shunt trip occupies the auxiliary release slot — no undervoltage release (UVR) on this variant. No communication module, no ground-fault monitoring; this is a straight line-protection breaker with remote trip capability.
