It breaks up to 100 kA at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V AC — the 100 kA SCCR means it safely interrupts fault currents up to that level without cascading upstream, critical for panel coordination. ## Mounting and wiring — DIN rail, screw terminals, clearances Zero clearance required at the back and sides — 0 mm backwards, 0 mm at the side — so it packs tight in a panel. Main circuit terminals are screw-type, accepting solid conductors 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), and stranded 2x (1…2.5 mm²) and 2x (2.5…6 mm²). The auxiliary switch is transverse design; the breaker accepts zero factory-fitted auxiliary contacts (0 for auxiliary contacts), but an add-on block can be wired in. Mechanical endurance of the main contacts is 100,000 operations typical.","metaTitle":"Siemens 3RV1021-1GA15-ZW97 SIRIUS Motor Protection CB, 6.3 A","metaDescription":"Siemens 3RV1021-1GA15-ZW97 SIRIUS motor protection circuit breaker, 6.3 A continuous, CLASS 10 trip, 100 kA SCCR at 400 V.
