| Design Of The Product | For motor protection |
The breaker also includes phase failure detection, so if one phase drops out, the unit opens the circuit before the motor single-phases and burns.
Depth is 97 mm, so it clears a 100 mm deep enclosure with a few mm to spare for wiring. The M3 main contact screws accept 2× 0.5–2.5 mm² solid or stranded conductors.
This gives you selectivity headroom downstream: you can coordinate with a feeder breaker without worrying about nuisance trips on a bolted fault.
Submit an RFQ through the storefront; the part is sourced to order and pricing is confirmed at quote time.
Both are 45 mm wide SIRIUS breakers on the same DIN rail footprint, so the physical swap is straightforward. The 3RV2011-1JA15-ZX95 carries a higher 100 kA breaking capacity at 400 V versus the 3RV1011-1HA10, so verify the downstream SCCR still coordinates.
The depth is 97 mm, which fits a standard 100 mm deep enclosure with clearance for wiring.
The width is 45 mm, matching the standard modular device footprint for DIN rail panels.
