Description
Built for industrial motor control, the Siemens 3RV1011-1FA10 is a SIRIUS series protector that safeguards three-phase equipment. It offers an adjustable thermal trip range from 3.5 to 5 amps, integrating overload and short-circuit defense into a single device. Designed with an S00 frame, this protector mounts onto standard 35mm DIN rails for streamlined panel assembly. Siemens has replaced this model with the 3RV2011-1FA10, but it remains fully compatible with legacy 3RV1 systems.Specifications

Product FAQs
7 answersWhat is the thermal overload adjustment range for the 3RV1011-1FA10?
The thermal overload release on this motor protection circuit breaker is adjustable from 3.5A to 5A.
What frame size is the 3RV1011-1FA10 motor starter protector?
This device is built on the Siemens SIRIUS Size S00 frame. It is compatible with standard S00 accessories, including auxiliary contacts and lateral link modules.
What is the tripping class for this Siemens motor protection circuit breaker?
The 3RV1011-1FA10 features a Class 10 tripping characteristic, providing reliable overload and short-circuit protection for standard motor applications.
Is the 3RV1011-1FA10 still in active production?
The SIRIUS 3RV1 generation has been phased out by Siemens. The direct successor for this model is the 3RV2011-1FA10, which offers the same 5A rating and S00 frame size in the newer 3RV2 series.
Can this circuit breaker be used as a Type E self-protected combination motor controller?
Yes, it can be applied as a Type E self-protected manual combination starter per UL 508. However, a dedicated Type E terminal block accessory is required to meet the necessary clearance and creepage standards for this installation.
How is the 3RV1011-1FA10 mounted inside an industrial control panel?
It is designed for standard 35mm DIN rail mounting. It can also be integrated into SIRIUS motor control assemblies or group installations where multiple motor starter protectors are fed from a single primary breaker.
Can I mount a contactor directly to this motor starter protector?
Yes, a SIRIUS Size S00 contactor can be mechanically and electrically linked to this unit using a dedicated link module to create a complete fuseless motor starter assembly.
