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. Three poles, line protection design, and a shunt trip (STL) auxiliary release built in. 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 415 V and 440 V it still holds 121 kA, which covers most industrial distribution panels. At 500 V it drops to 75.6 kA, and at 690 V it's down to 3.7 kA. The 690 V figure is essentially a residual rating; this breaker is not intended for 690 V motor circuits with significant fault current. Match your system's available fault current at the point of installation against the voltage column that matches your line-to-line voltage.
Physical footprint and panel fit
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
Rated insulation voltage is 800 V. Maximum power loss is 25.5 W.
