Typical application scenarios

Industrial machinery:
Protection for main shaft motors or auxiliary motors of equipment such as lathes, milling machines, conveyor belts, packaging machinery, and textile machinery.
Material transportation:
Protection for drive motors of fluid machinery and solid material transportation equipment such as pumps, fans, compressors, and crushers.
Automated production lines:
In automated equipment such as assembly lines and inspection lines, Siemens 3RV6011-1KA15 provides reliable protection and control for motors at each workstation.

Comprehensive motor protection

1. With the adjustable bimetallic thermal trip unit, the setting range is 9 - 12.5A, effectively preventing the motor from being damaged due to long-term overloading.
2. With the electromagnetic short-circuit trip unit, set at 156A, it can instantly cut off the short-circuit current, protecting the motor and the circuit.
3. Siemens 3RV6011-1KA15 has a phase loss detection function. A loss of current will trigger the trip, preventing the motor from burning out due to phase loss operation.

High reliability and long lifespan

Mechanical life: Up to 100,000 operation cycles.
Electrical life: Up to 100,000 operation cycles.
High breaking capacity:
Capable of handling severe short-circuit faults in industrial sites, with a rated short-circuit breaking capacity of up to 100kA.
Compact design and easy installation:
Uses screw terminal blocks, belonging to the S00 frame size, with a compact volume.
Standard DIN rail installation, convenient and quick.
Auxiliary functions:
Includes 1 normally open (NO) and 1 normally closed (NC) auxiliary contacts, used for remote signal indication, control interlock or alarm.
Can it be directly substituted for the thermal relay?
Sure. It also provides overload protection and short-circuit protection, and its protection range is more comprehensive than using a thermal relay alone.
How to correctly adjust the overload protection current?
There is a calibrated adjustment knob on the front of the circuit breaker. Using a flat-head screwdriver, align the indicator arrow on the knob with the required value, which should be between 9 A and 12.5 A.
Can the circuit breaker be used for single-phase motors or pure lighting/resistance loads?
Not recommended. The Siemens 3RV6011-1KA15 is specifically designed for three-phase motors. The internal phase-break protection function and the thermal bimetallic strip are set for the startup and operation curves of three-phase motors. For single-phase loads, a single-phase circuit breaker or a regular miniature circuit breaker should be selected.
Does it have auxiliary contacts?
Yes, it is configured with 1NO + 1NC auxiliary contacts, which can be used for status feedback, PLC signal input, and alarm control.
