An auxiliary switch is included, giving the integrator a status contact to wire back into a PLC input or indicator without sourcing a side-mounted aux block; zero auxiliary contacts are listed in the auxiliary-circuit count field, so the integral switch is the only one on the device. Operating ambient is -20 to +60 °C, transport and storage are -50 to +80 °C, maximum installation altitude is 2 000 m, and shock resistance is 25g / 11 ms — a robust industrial envelope that does not need derating in a normal factory-floor panel. ## Panel-side mounting and wiring The breaker snaps onto a 35 mm standard mounting rail per DIN EN 50022 with screw support, mounts in any position, and measures 45 mm wide, 96 mm deep, and 97 mm tall — a slim vertical profile that keeps DIN-rail real estate tight in multi-starter panels; front-of-panel touch protection is IP20. Main current terminals are screw-type and accept 2x (1... 2.5 mm²) plus 2x (2.5... 6 mm²) for solid, stranded, and finely stranded with ferrule conductors, with the AWG range of 2x (14... 10) covering the equivalent North American wire sizes. ## Thermal budget inside the enclosure Total power dissipation is 5.5 W in the hot operating state, or 1.8 W per pole, which enclosure thermal sizing must absorb per installed breaker. ## Sourcing posture","metaTitle":"Siemens 3RV1021-0BA10-0FJ0 circuit breaker, 0.2 A, 690 V","metaDescription":"Siemens SIRIUS 3RV1021-0BA10-0FJ0 motor protection circuit breaker, 0.2 A continuous, 690 V AC-3, CLASS 10 trip, 100 kA SCCR, auxiliary switch.
