Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) solid or 2x (1…2.5 mm²) stranded — common for panel wiring with ferrule or direct termination. Auxiliary contacts are transverse design; the breaker ships with an auxiliary switch block fitted (0 built-in auxiliary contacts on the base unit, so the switch is an add-on module). ## Environmental limits and mounting Rated for -20 to +60 °C operating ambient, storage down to -50 °C, with shock resistance of 25 g / 11 ms — suitable for machine-mounted panels on presses or conveyors. Mountable in any position, with zero clearance required at the sides or rear — no derating needed for tight panel layouts.","metaTitle":"Siemens 3RV1021-1FA15-ZX95 SIRIUS Motor Circuit Breaker, 5 A","metaDescription":"Siemens 3RV1021-1FA15-ZX95 SIRIUS motor protection circuit breaker, 5 A continuous, Class 10 trip, 100 kA breaking at 400 V.
