The CLASS 10 trip characteristic matches standard motor start profiles, allowing the breaker to ride through the inrush without nuisance tripping. ## Breaking capacity and fault clearance Short-circuit breaking capacity is a flat 100 kA across the AC voltage range from 240 V to 690 V (–). The 100 kA rating is the same at 400 V and 690 V, so it holds up even on 690 V industrial grids. Main circuit terminals accept solid conductors from 2x (0.5... 1.5 mm²) to 2x (0.75... 2.5 mm²) and stranded from 2x (1... 2.5 mm²) to 2x (2.5... 6 mm²). Auxiliary and control circuit terminals are also screw-type, so the whole unit is wired with one screwdriver. IP20 front protection is standard for enclosed panels. ## Auxiliary switch and control signals The breaker accepts a transverse auxiliary switch — the product extension is available, meaning you can add a signal contact for remote fault indication or PLC input. The auxiliary contacts are rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V. These ratings are for the control circuit; the main power path handles the motor current.","metaTitle":"Siemens 3RV1021-0EA15-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-0EA15-ZW98 motor protection circuit breaker, 0.4 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.
