Product details

At 400 V, the maximum fuse backup rating is gL/gG 50 A; at 500 V it drops to 40 A, and at 690 V to 35 A — so if you are using this in a high-fault installation, the upstream fuse must be sized to these limits to maintain the rated breaking capacity. Motor horsepower ratings are listed per voltage: 2 hp at 200/208 V, 5 hp at 460/480 V and 575/600 V, and 1 hp at 230 V — these are the NEMA-equivalent loads the breaker can handle in AC-3 duty.

Dimensions: 45 mm wide, 106 mm high, 97 mm deep — the width is a single modular unit, so it occupies one slot on the DIN rail.

Lifecycle stage is current production.

Frequently asked questions

Will the 3RV2311-1HC20 drop into a panel built for the 3RV2021-1GA25?

The 3RV2311-1HC20 is a SIRIUS circuit breaker for starter combinations, same DIN-rail footprint (45 mm wide), but the 3RV2021-1GA25 is a different frame size — check the physical dimensions and terminal layout against your panel drawing before assuming a drop-in fit.
