The Siemens 3VA2116-5HL36-0JA0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current across its full ambient temperature range of -25 °C to 70 °C — no derating needed up to the 70 °C ceiling. This is the variant that carries a voltage trigger but no undervoltage release and no ground-fault monitoring.
Breaking capacity — what the voltage columns mean for your fault level
The interrupting rating is given at five system voltages, and the spread tells you where this breaker is comfortable and where it isn't. At 240 V it clears 187 kA — that's a very high fault-current capability for a 160 A frame, typical of a high-end MCCB on a low-voltage transformer secondary. At 500 V it drops to 75.6 kA, and at 690 V it's down to 3.7 kA.
Dimensions are 181 mm high by 105 mm wide by 86 mm deep (7.13 × 4.13 × 3.39 in). The 105 mm width is standard for a 3-pole 160 A frame in the SENTRON 3VA2 family — it occupies three 35 mm DIN-rail module positions, though this breaker is likely bolt-on or plug-in base mounted rather than snap-on. Confirm the mounting base (3VA21165HL360AA0 is the supplied basic switch) before panel layout.
Auxiliary release — shunt trip (STL)
The shunt trip release (STL) is factory-installed. It allows remote tripping by applying a control voltage to the release coil — standard for emergency-stop circuits, fire-safety interlocks, or PLC-driven disconnect sequences. No undervoltage release is present on this variant; if UVR is needed for your safety circuit, this is not the right order code.
Rated insulation voltage and power loss
Maximum power loss is 25.5 W.
