Product details

It's sized for a 3 kW motor at 400 V AC.

Breaking capacity and fault handling

The 6 000 V rated surge voltage resistance means it can ride through transient spikes common on motor circuits without nuisance tripping.

Mounting position is any — horizontal, vertical, upside-down, whatever the panel layout needs. The IP20 front face means it's finger-safe when installed in a closed panel. Spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. For AWG, that's 2x (24... 14). No torque spec to chase — just strip to 8-10 mm and push in.

Shock rated at 25 g for 11 ms — survives rough handling during shipping. RoHS compliance date is 01.01.2013 — it's been RoHS-compliant since then. The part carries finger-safe touch protection and surge voltage resistance at 6 000 V.

Frequently asked questions

Will 3RV1011-1HA20 drop into a panel specified for 3RV1011-1HA10?

Yes — same 45 mm width, same DIN-rail mounting, same spring-loaded terminal layout. The main difference is the 3RV1011-1HA20 is rated 8 A continuous versus the 1HA10's lower current rating. No rewiring needed if the load current is within the 8 A rating.
