That flat thermal curve simplifies panel sizing when the breaker sits near other heat sources. Its interrupting capacity hits 187 kA at 240 V AC and still delivers 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V. For a line-protection MCCB with integrated ground-fault monitoring (summation-current method on L+N), those numbers give you selectivity headroom downstream without cascading an expensive upstream breaker. The 3VA2116-5JQ42-0AA0 occupies 140 mm width, 181 mm height, and 86 mm depth on the DIN rail or panel-mount footprint. Its communication function (protocol not specified in this data) allows integration into a plant-wide monitoring scheme — useful for a brownfield retrofit where you want breaker status on the SCADA without adding a separate I/O module. ## Ground-fault and protection architecture This breaker includes ground-fault monitoring via summation current formation on the L+N conductor — a common approach for solidly-grounded systems where you want to detect leakage without a separate GFCI module. The trip indicator is absent, so fault events are signaled through the communication interface rather than a local flag.","metaTitle":"Siemens 3VA2116-5JQ42-0AA0 SENTRON MCCB, 160 A, 4-Pole, 187","metaDescription":"Siemens 3VA2116-5JQ42-0AA0 SENTRON molded case circuit breaker. 160 A continuous, 4-pole, 187 kA breaking at 240 V.
