The Siemens 3RV2032-4JA10 is a SIRIUS 3RV2 motor starter protector (circuit breaker for motor protection) in size S2, with a thermal overload release adjustable from 54 … 65 A and a magnetic short-circuit release at 845 A. Per Siemens it suits motors of about 30 kW at 400 V and has a rated short-circuit breaking capacity (Icu) of 100 kA at 400 V.
Siemens describes this unit as: Circuit breaker size S2 for motor protection, CLASS 10 A-release 54…65 A N- release 845 A screw terminal increased switching capacity. Its instantaneous release at 845 A is set well above the motor starting current, so normal starts do not trip it.

Typical applications
- Machine-builder panels where a lockable rotary isolator is required
- Motor branch circuits with full-load currents between 54 … 65 A
- Replacement of a tripped or damaged 3RV2 breaker
- Protection of pumps, fans, conveyors and compressors
Compatibility and replacement
Auxiliary switches for status feedback can be added on the front (transverse, for example 3RV2901-1E) or on the left side (3RV2901-1A). The older 3RV10 series has been replaced by the 3RV20; send us the old order number and we will confirm the matching setting range.
Frequently asked questions
What motor current can it protect?
The overload release is adjustable from 54 … 65 A. Set it to the rated current shown on the motor nameplate.
Can it be locked off?
Yes, the rotary handle can be locked in the OFF position with a padlock, which is required for safe maintenance in many plants.
At what current does it trip instantly?
The magnetic (N) release responds at 845 A, per Siemens.
