For motor or distribution panels on a 400 V supply, that rating covers most industrial fault currents without needing an upstream current-limiting device. ## Protection settings and auxiliary wiring Overload protection is fixed at Ir = 20 A (non-adjustable). Short-circuit protection is set at Ii = 16 x In, or 320 A — a magnetic-only instantaneous pickup that clears hard faults fast. Two HQ auxiliary switches report the main contact position to a PLC or status lamp.","metaTitle":"Siemens 3VA1020-2ED36-0BC0 Circuit Breaker, 20A, 16kA @ 415V","metaDescription":"Siemens 3VA1020-2ED36-0BC0 IEC frame 100 circuit breaker, 3-pole, 20A TM210, Icu=16kA @ 415V, UVR 24V DC, 2 aux switches.
