Its headline breaking capacity is 150 kA at 415 V — class L, meaning it handles very high fault currents typical of large industrial distribution or transformer secondary feeds. The continuous current rating In is 40 A, with overload protection Ir adjustable from 16 A to 40 A, and short-circuit protection Ii adjustable from 1.5 to 12 times In. That adjustability lets you fine-tune coordination with downstream breakers without swapping the trip unit. ## Integration Notes The clamp (screwless) terminals accept copper conductors — strip length and torque values per the Siemens mounting sheet. For selectivity studies, the ETU320 LI curve coordinates with downstream 10–25 A breakers in most 415 V networks.","metaTitle":"Siemens 3VA2040-8HL36-0AF0 Circuit Breaker, 150kA @ 415V, 40","metaDescription":"Siemens 3VA2040-8HL36-0AF0 IEC frame 100 circuit breaker, Icu=150kA @ 415V, 40A, ETU320 LI protection, auxiliary & alarm switches.
