For a 0.2 A motor branch, that level of fault-interrupt capability is overkill on the load side but essential for the line-side short-circuit rating the panel designer needs to pass the SCCR label. Main and auxiliary/control circuits use screw-type terminals. Each pole accepts two solid or stranded conductors in the range 1 to 2.5 mm², plus a second pair for 2.5 to 6 mm² — handy for daisy-chaining the line feed through the breaker without a separate terminal block. AWG equivalents are 2x (14 to 10) for the main contacts. Rated for -20 to +60 °C operating ambient, -50 to +80 °C storage/transport. Shock-tested to 25 g for 11 ms — survives the ride in a panel on a forklift or a conveyor line vibration. Phase-failure detection is built in; ground-fault detection is not. An auxiliary switch can be added via the product extension slot.","metaTitle":"Siemens 3RV1021-0BA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0BA10-ZX95 SIRIUS motor protection circuit breaker, 0.2 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V, IP20 front.
