Design Of The ProductFor starter combinations

Product details

Backup fuse coordination is specified as gL/gG 32 A at 400 V and 500 V, and 25 A at 690 V. That means the upstream fuse must be sized to those limits to guarantee the breaker clears a fault inside its envelope — skip the fuse and you lose the SCCR rating.

Dimensions are 97 mm deep, 45 mm wide, and 97 mm tall — a 45 mm wide footprint on the DIN rail, so it occupies one standard 45 mm module slot. Terminal screws for the main contacts are M3, accepting 2x (0.75 to 2.5 mm²) solid or stranded, or 2x 4 mm². No ground-fault or phase-failure detection built in — that's handled by the contactor or an external relay in the starter combination.

Frequently asked questions

What is the closest second-source to 3RV2311-1EC10?

The 3RV2311-1CC10 is a close sibling in the same SIRIUS series, sharing the same 45 mm width and DIN-rail mount. The key difference is the SCCR and backup fuse coordination — verify your fault current requirements before swapping. No rewiring needed if the terminal assignments match.
