| Design Of The Product | For motor protection |
Mounting position any. Fastening for main contacts uses M4 screws. Conductor cross-section: 2x (0.5... 1.5 mm²) solid or stranded, or 2x (0.75... 2.5 mm²). Minimum clearance distances: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards — so it can be packed tight against the back panel and adjacent devices on the rail.
It is sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time.
The listed depth is 97 mm.
The listed width is 45 mm.
Both are motor protection circuit breakers from the Siemens SIRIUS family, but the 3RV2021-4EA15-ZX95 has a 45 mm width versus the 3RV1011-1HA10's narrower 45 mm? (Note: 3RV1011-1HA10 width is not in evidence; the 3RV2021-4EA15-ZX95 width is 45 mm. Panel fit should be verified against the existing cutout and wiring — the 3RV2021-4EA15-ZX95 uses M4 main contact screws and accepts 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) conductors, so rewiring may be needed if the original used different terminals.)
