Product details

That high SCCR simplifies panel coordination — no need for a larger upstream fuse just to protect this branch. Terminals are spring-loaded on both the main and auxiliary circuits, accepting 2x (0.25... 2.5 mm²) solid or 2x (24... 14) AWG stranded. Mounting position is any. IP20 on the front face keeps fingers out.

The integrated auxiliary switch is rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V. That covers PLC-level control signals and contactor coils in most panels. The transverse design means the contact block sits alongside the main body — no extra depth beyond the 81 mm listed.

Shock rated at 25g / 11 ms. RoHS compliance date is 01.01.2013 — the part meets EU substance restrictions. Power loss in hot operating state is 5.5 W.

Frequently asked questions

What is 3RV1011-0JA25 used for?

It is a motor protection circuit breaker for a 0.25 kW motor at 400 V, with 1 A continuous rating and CLASS 10 trip. Use it to protect three-phase induction motors against overload and phase failure.

What is the breaking capacity of 3RV1011-0JA25?

100 kA at 240 V, 400 V, 500 V, and 690 V AC. That is a high short-circuit current rating for a 1 A breaker — it can clear a bolted fault without upstream coordination.

Will 3RV1011-0JA25 drop into a panel specified around 3RV1011-0HA10?

Both share the same 45 mm width, 90 mm height, and 35 mm DIN-rail mounting with zero side/back clearance. The terminal type and wire range are the same spring-loaded design. Mechanical fit is identical; verify the trip current rating matches your motor FLA.

Where can I buy 3RV1011-0JA25?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
