Product details

The overload release adjusts from 2.8 to 4 A via a dial, and it comes with a built-in transverse auxiliary switch (1 NO + 1 NC) for status feedback.

The adjustable overload range of 2.8…4 A covers small motors in the 0.75–1.5 kW ballpark at 400 V (the part is rated 1500 W at 400 V). The magnetic short-circuit trip responds at 52 A (N release), clearing faults before the contactor welds. Size S00 keeps the footprint compact — 45 mm wide — so it fits neatly on a DIN rail alongside a S00 contactor in a motor starter assembly. The screw-type terminals accept 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid/stranded wire, and the mounting position is unrestricted (any orientation).

Frequently asked questions

What is the trip class of this circuit breaker?

The trip class is CLASS 10, meaning it trips within 10 seconds at 7.2× the set overload current — suitable for standard motor starting profiles.

What mounting does this part require?

It mounts via screw and snap-on onto a 35 mm standard mounting rail per DIN EN 60715, and can be installed in any position.

Will 3RV1011-1EA15-ZI45 drop into a panel specified around 3RV1011-1HA10?

Both are size S00, same DIN-rail footprint and screw-terminal arrangement, so the mechanical fit is identical. The key difference is the current range: this one adjusts 2.8–4 A, while the 1HA10 covers 5.5–8 A. If the motor load falls within 2.8–4 A, it is a direct swap without rewiring.

Where can I buy 3RV1011-1EA15-ZI45?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an inquiry for a firm quote.
