That 50 mm vertical gap is for the arc-chute exhaust; don't cram it into a tight enclosure without that headroom. Any mounting position works, and the part is rated for -20 to +60 °C operating ambient. If it's in a hot cabinet next to a drive, that 11 W typical power loss adds up — keep ventilation in mind when grouping several units. ## Wiring and connections Main circuit terminals are screw-type, accepting 2 × (0.5…1.5 mm²) solid/stranded or 2 × (0.75…2.5 mm²) finely stranded with ferrules. AWG equivalents: 2 × (16…12) or 2 × (14…8). Torque to 2…2.5 N·m. Auxiliary contacts use the same screw-terminal style with slightly smaller wire ranges (2 × 20…16 AWG or 2 × 18…14 AWG). The auxiliary switch is transverse-mounted, so check your panel layout for actuator clearance.","metaTitle":"Siemens 3RV6021-4EA15 SIRIUS Motor Protection CB, 32 A Class","metaDescription":"Siemens 3RV6021-4EA15 SIRIUS motor protection circuit breaker, 32 A rated, Class 10 trip, 690 V AC-3, S0 frame, DIN rail mount.
