The Siemens 3RV2032-4XA10 is a SIRIUS 3RV2 motor starter protector (circuit breaker for motor protection) in size S2, with a thermal overload release adjustable from 49 … 59 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.
Set the overload dial to the full-load current on the motor rating plate. If the breaker trips repeatedly, check the motor, the mechanical load and the supply phases before raising the setting.

Typical applications
- Machine-builder panels where a lockable rotary isolator is required
- Replacement of a tripped or damaged 3RV2 breaker
- Protection of pumps, fans, conveyors and compressors
- Transformer and control circuit protection where a motor-type characteristic is acceptable
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). Choose the setting range so that the motor full-load current sits roughly in the middle of the dial; this leaves room for adjustment.
Frequently asked questions
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.
Can it replace a fuse and overload relay?
Yes. A motor starter protector provides both short-circuit and overload protection, so in a typical starter it replaces the fuses and the separate overload relay.
Which contactors can it be combined with?
Per Siemens: contactor sizes S2.
