The 2.5 A continuous rating and 0.75 kW at 400 V AC-3 tell you this breaker is sized for a small motor — think a 1 HP pump or a fractional-horsepower conveyor drive. The CLASS 10 trip ensures it clears a locked rotor before the motor winding insulation degrades. No ground-fault detection here — that's handled separately downstream if needed. RoHS compliance date is 01.05.2012, meaning it meets the EU substance restrictions that went fully effective in 2011. No REACH or UL listing is on record here, but the SIRIUS series typically carries UL/CSA certification for North American panels — verify the specific listing against your local code if that's a gate. ## Integration notes Zero clearance at sides and rear means you can abut breakers without spacing — useful when you're filling a 600 mm-wide enclosure and every millimeter counts. Auxiliary switch extension is supported, so you can add a signal contact for remote status or PLC input without rewiring the main circuit. The auxiliary terminals are screw-type, same as the main circuit. Power dissipation is 7.25 W total hot (2.4 W per pole), which matters for thermal rise in a sealed enclosure — factor that into your cabinet cooling calc if you're stacking a row of these.","metaTitle":"Siemens 3RV1021-1CA10-ZW98 SIRIUS Motor Circuit Breaker, 2.5","metaDescription":"Siemens 3RV1021-1CA10-ZW98 SIRIUS motor-protective circuit breaker, 2.5 A continuous, CLASS 10 trip, 100 kA at 400 V, screw terminals, 45 mm wide, current production.
